B4J: ABMaterial 3.20 Public/3.50 Donators Released!

ABMB4JABMaterial 3.50 for B4J introduces Drag & Drop of ABMContainers between Cells! This new feature took a couple of weeks to implement, but I’m proud of the result.
It opens up a whole new range of possibilities for Web Apps.

Not many bug fixing needed in this release. Proves ABMaterial is really stable and truly production ready! (Happy face)

ABMGoogleMap also adds the possibility to use marker clusters, which cleans up your google map if you have many markers in one map.

B4X: ABMaterial 3.03 Public/3.20 Donators released

A lot of internal changes were made in the ABMaterial 3.20 ‘Chipmunk’ release.  For example, ABMContainer has been rewritten from the ground-up, but with minimal impact to your existing projects.  It allows adding them as array components, and has much shorter ID tags in the generated HTML.

Mindful and Stanmiller had another go on the cache issues.  They came up with a very nice solution (I had tears in my eyes) and both have done extensive testing on this subject. A big thanks again!  ABM 3.20 is backwards compatible with the previous 3.0.3 Cache System, but I would advice you to make the changes whenever you have the chance.

A nice new feature for mobile devices is the New Debug feature using a modified version of Conzole!

New Debug at work:

Using this new feature is very simple in B4J:

First, you have to enable the console in BuildPage():

' params are: open on load, width
page.DebugConsoleEnable(True, 300)

Two methods can be used to show or hide the console programmaticaly. Can be handy as a buid-in tool in your apps where the user enters a code on his device and you can then check the console.

page.DebugConsoleShow
page.DebugConsoleHide

Now you can start doing some cool stuff 🙂 Some examples:

Show some text, or a server value (note: strings must be between single quotes!)

page.DebugConsoleLog("'Server click at: " & DateTime.Time(DateTime.Now) & "'") ' shows the text

Now I generated an error on purpose, so the demo can show it catches the error:

page.DebugConsoleLog("'value: ' + $('#pi002-r2c1').html();") ' generates an error, the ; at the end is wrong

Same code, but with the correct javascript syntax, showing the html() value of the tag:

page.DebugConsoleLog("'value: ' + $('#pi002-r2c1').html()") ' generates the html value of the pi002-r2c1 tag

It works also on the desktop, although you probably will use the Chrome console as you can do more.

But there is more. You can also redirect all browser console message directly into the B4J log window!  You can use the following commands anywhere in your own code to start/stop receiving the browser console messages.

page.DebugConsoleB4JStart
page.DebugConsoleB4JStop

This is a very powerful feature if you develop Webapps for mobile devices.  It can be done otherwise, but it is a pain in the a$$ to set it up. Now, you can easily debug it on your iPhone, iPad, Android or any other device.

ABMaterial 3.20 has over 20 new features and bug fixes.  Following the same philosophy as B4X, the quick release cycle has proven to work very well for ABMaterial and its many users.  Donators will receive their download mail shortly.  The public version 3.03 can be downloaded from this blog too.

I’m also glad that with these releases, now everyone can work with ‘Chipmunk‘, and this does also mean the development cycle for ‘Butterfly‘  has ended.

I would like to take this opportunity to thank everyone for the support, hourless testing and inventive ideas you came up with in the last few years. You’ve made ABMaterial one hell of a WebApp Development Tool!

ThankYou

But we are not at the end! Far from it as I already have big ideas for the next releases.

Until then, happy programming!

B4A: ABFlicB4A library for Flic buttons

cute-as-a-button-1

You probably have seen these nifty little IoT Flic buttons around. They are a fun and relative cheap BLE button that allows you to do something when the button is clicked, doubleclicked or hold.

I decided to write a wrapper for the Android SDK to use with B4A.

How to use:
1. Install the Flic app from the Google Play.
2. On their developer page, create a new app: you get a key and a secret.
3. Copy the ABFlicB4A library jar and xml to your library folder and select it in B4A

Here is a small video demonstrating the library.  You can the use the full power of B4A to do about, well, everything…

Example usage code:

Sub Process_Globals

End Sub

Sub Globals
   Private flic As ABFlic
   Private Button2 As Button
   Private Button3 As Button
   Private Button4 As Button
   Private Label1 As Label
   Private Button1 As Button

   Private MyFlicID As String

   Private FlicResults As List
End Sub

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("1")
   FlicResults.Initialize
   FlicResults.Add("RESULTACTION_HOLD")
   FlicResults.Add("RESULTACTION_SINGLECLICK")
   FlicResults.Add("RESULTACTION_DOUBLECLICK")
End Sub

Sub Activity_Resume
   ' your key and secret
   flic.Initialize("Flic", "d60d36a0-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", "db5c2b3d-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX", "ABFlicTest")
End Sub

Sub Button1_Click
   flic.ForgetButton(MyFlicID)
End Sub

Sub Button2_Click
   flic.GrabButton
End Sub

Sub Button3_Click
   flic.StartListening
End Sub

Sub Button4_Click
   flic.StopListening
End Sub

Sub flic_Added(buttonID As String, Name As String)
   MyFlicID = buttonID
   Log("Added: " & buttonID)
   Label1.Text = "Added: " & buttonID & CRLF & Label1.Text
End Sub

Sub flic_Clicked(buttonID As String, wasQueued As Boolean, timeDiff As Int)
   MyFlicID = buttonID
   Log("Clicked: " & buttonID)
   Label1.Text = "Clicked: " & buttonID & CRLF & Label1.Text
End Sub

Sub flic_DoubleClicked(buttonID As String, wasQueued As Boolean, timeDiff As Int)
   MyFlicID = buttonID
   Log("DoubleClicked: " & buttonID)
   Label1.Text = "DoubleClicked: " & buttonID & CRLF & Label1.Text
End Sub

Sub flic_Holded(buttonID As String, wasQueued As Boolean, timeDiff As Int)
   MyFlicID = buttonID
   Log("Holded: " & buttonID)
   Label1.Text = "Holded: " & buttonID & CRLF & Label1.Text
End Sub

Sub flic_Removed(buttonID As String)
   MyFlicID = ""
   Log("Removed: " & buttonID)
   Label1.Text = "Removed: " & buttonID & CRLF & Label1.Text
End Sub

Sub flic_Error(err As Int)
   Log("Error: " & err)
   Label1.Text = "Error: " & err & CRLF & Label1.Text
End Sub

I’m currently working on a Desktop/Raspberry Pi version of this library, which I will share in the B4J forum later.

The library can be found at the B4A forum.

Happy programming!

B4J: New ABMChat component for ABMaterial 2.50

abmchat

ABMChat is a new cool looking ABMaterial component to create a Web based chat program. The inner workings are very much like Erels ChatRoom, but with a slick interface. This can be a useful control if for example you want to give chat-like support within you own B4J webapp.

Some features:
– Balloon/Bubble-like chat
– Support for some ASCII emoji
– IsTyping ballon

Coding this with B4J and ABMaterial is very easy:

Code ChatShared module:

Sub Process_Globals
   Public AvoidDuplicates As Map
   Private connections As Map
   Public LastMessages As List
   Private IsTypingMap As Map
End Sub

public Sub Init
   AvoidDuplicates = Main.srvr.CreateThreadSafeMap
   connections.Initialize
   LastMessages.Initialize
   IsTypingMap.Initialize
End Sub

public Sub NewConnection(page As ChatPage, pageID As String)
   DateTime.TimeFormat = "HH:mm"

   Dim IdentifyBubble As ABMChatBubble
   IdentifyBubble.Initialize("Server", page.ChatName & " has joined the chat...", "Server " & DateTime.Time(DateTime.Now), "server", "server")
   JoinLeftMessage(pageID, IdentifyBubble)
   connections.Put(pageID, page)
   CallSubDelayed2(page, "CurrentConversation", LastMessages)
End Sub

public Sub NewMessage(pageID As String, Message As ABMChatBubble)
   LastMessages.Add(Message)
   For Each page As ChatPage In connections.Values
     CallSubDelayed2(page, "NewMessage", Message)
   Next
End Sub

public Sub JoinLeftMessage(pageID As String, Message As ABMChatBubble)
   For Each page As ChatPage In connections.Values
     CallSubDelayed2(page, "NewMessage", Message)
   Next
End Sub

public Sub IsTyping(pageID As String, Value As String)
   Dim typeBool As Boolean
   If Value = "" Then
     IsTypingMap.Remove(pageID.ToLowerCase)
   Else
     IsTypingMap.put(pageID.ToLowerCase, "true")
   End If
   If IsTypingMap.Size > 0 Then
     typeBool = True
   End If
   For Each page As ChatPage In connections.Values
     CallSubDelayed3(page, "IsTyping", pageID, typeBool)
   Next
End Sub

public Sub Disconnected(page As ChatPage, pageID As String)
   If connections.ContainsKey(pageID) = False Or connections.Get(pageID) <> page Then Return
   Dim LeaveBubble As ABMChatBubble
   LeaveBubble.Initialize("Server", page.ChatName & " has left the chat...", "Server " & DateTime.Time(DateTime.Now), "server","server")
   JoinLeftMessage(pageID, LeaveBubble)
   connections.Remove(pageID)
   AvoidDuplicates.Remove(pageID.ToLowerCase)
End Sub

Public Sub HasIdentified(pageID As String) As Boolean
   Return connections.ContainsKey(pageID)
End Sub

Relevant Code ChatPage class:

Private Sub WebSocket_Disconnected
   Log("Disconnected")
   If ABMPageId <> "" Then CallSubDelayed3(ChatShared, "Disconnected", Me, ABMPageId)
End Sub

public Sub BuildTheme()
   ' start with the base theme defined in ABMShared
   theme.Initialize("pagetheme")
   theme.AddABMTheme(ABMShared.MyTheme)

   ' add additional themes specific for this page
   theme.AddChatTheme("myChat")
   theme.Chat("myChat").AddBubble("server")
   theme.Chat("myChat").Bubble("server").Color = ABM.COLOR_BLACK
   theme.Chat("myChat").Bubble("server").TextColor = ABM.COLOR_WHITE

   theme.Chat("myChat").AddBubble("me")
   theme.Chat("myChat").Bubble("me").Color = ABM.COLOR_LIGHTBLUE
   theme.Chat("myChat").Bubble("me").TextColor = ABM.COLOR_WHITE

   theme.Chat("myChat").AddBubble("them")
   theme.Chat("myChat").Bubble("them").Color = ABM.COLOR_GREY
   theme.Chat("myChat").Bubble("them").ColorIntensity = ABM.INTENSITY_LIGHTEN2
   theme.Chat("myChat").Bubble("them").TextColor = ABM.COLOR_BLACK
End Sub

public Sub ConnectPage()
'   connecting the navigation bar    

'   init all your own variables (like a List, Map) and add your components
   Dim chat As ABMChat
   chat.Initialize(page, "conversation",600, 450, 255, "mychat")
   chat.AddBubble("Server", "I'm Server, what is your name?", "The Server", "server", "server")

   page.Cell(1,1).AddComponent(chat)

   Dim ChatInput As ABMInput
   ChatInput.Initialize(page, "ChatInput", ABM.INPUT_TEXT, "", False, "")
   ChatInput.PlaceHolderText = "Type your message here...."
   ChatInput.RaiseChangedEvent = True
   page.Cell(2,1).AddComponent(ChatInput)

   ' refresh the page
   page.Refresh
   ' Tell the browser we finished loading
   page.FinishedLoading
   ' restoring the navigation bar position
   page.RestoreNavigationBarPosition
End Sub

Sub ChatInput_Changed(value As String)
   If ChatShared.HasIdentified(ABMPageId) Then
     CallSubDelayed3(ChatShared, "IsTyping", ABMPageId, value)
   End If
End Sub

Sub ChatInput_EnterPressed(value As String)
   DateTime.TimeFormat = "HH:mm"

   If ChatShared.HasIdentified(ABMPageId) Then
     Dim bubble As ABMChatBubble
     bubble.Initialize(ChatName, value, ChatName & " " & DateTime.Time(DateTime.Now), "me", "them")
     CallSubDelayed3(ChatShared, "NewMessage", ABMPageId, bubble)
     CallSubDelayed3(ChatShared, "IsTyping", ABMPageId, "")
   Else
     If value = "" Then Return
     If ChatShared.AvoidDuplicates.ContainsKey(value.ToLowerCase) Then
       Dim chat As ABMChat = page.Component("conversation")
       chat.AddBubble("Server", "Sorry, but " & value & " is already taken!", "The Server", "server", "server")
       chat.Refresh
     Else
       ChatName = value
       ChatShared.AvoidDuplicates.Put(value.ToLowerCase, value)
       Dim chat As ABMChat = page.Component("conversation")
       chat.SetMyFrom(ChatName)
       chat.AddBubble("Server", "Welcome to ABMChat " & ChatName & "!", "The Server", "server", "server")
       chat.Refresh
       CallSubDelayed3(ChatShared, "NewConnection", Me, ABMPageId)
     End If
   End If

   Dim ChatInput As ABMInput = page.Component("ChatInput")
   ChatInput.Text = ""
   ChatInput.Refresh
End Sub

public Sub NewMessage(bubble As ABMChatBubble)
   Dim chat As ABMChat = page.Component("conversation")
   chat.AddBubble2(bubble)
   chat.Refresh
   chat.ScrollToBottom   ' scroll to the end of the chat
End Sub

public Sub IsTyping(pageID As String, typeBool As Boolean)
   Dim chat As ABMChat = page.Component("conversation")
   If pageID <> ABMPageId Then
     If typeBool = False Then
       chat.ThemAreTyping(False, "") 'hide the 'is typing' bubble
     Else
       chat.ThemAreTyping(True, "") ' show the 'is typing' bubble if not yet shown
     End If
     chat.Refresh
     chat.ScrollToBottom   ' scroll to the end of the chat
   End If
End Sub

public Sub CurrentConversation(LastMessages As List)
   If LastMessages.Size > 0 Then
     Dim chat As ABMChat = page.Component("conversation")
     chat.SetConversation(LastMessages)
     chat.Refresh
     chat.ScrollToBottom   ' scroll to the end of the chat
   End If
End Sub

So, there you have it. A complete modern looking multichat webapp that runs on all platforms in just about 150 lines of code!

B4J: ABMaterial Public 1.22/Donators 2.00 now released

It has been a long night to get everything ready, but I’m happy to release the new version(s) of ABMaterial for B4J!

2.00 is a major release.  Lots of new stuff and some changes that were really needed in preparation of the upcoming (ABMaterial Abstract Desinger) ABMAD tool.

Highlights of the releases:

1.22: New component ABMPatternLock

ABMPatternLock is yet another authentication method you can use based on the popular Pattern Lock you see in e.g. Android.

patternlock

1.22: ABMContainer can collapse

ABMContainer can be initialized as a collapsable component.  As a collapsable has a header and a body and clicking on the header will collapse/expand the body.  This can be used as an alternative for an ABMCard so you can build your own.

1.22: Support for Font-Awesome icons

If you set: page.UseFontAwesome = true then you can, next to the material icons, also use the Font Awesome Icon library (634 icons in used version Font Awesome 4.6.3)
See fontawesome.io for a list of icons.

fontawesome

2.00: New component ABMChronologylist

The ABMChronologyList is a vertical timeline component. Useful to give an overview of a limited period. It is device aware so e.g. on a phone, all items will be one under each other.

chronology

2.00: New helper ABMSideBar

In ABMaterial 2.00, you will be able to define multiple side bars (sliding in from the right). I’ve tried to mimic the usage of ABMSideBar as much of the existing Side Navigation menu. The tricky part was making it work well with the NavigationBar, on all screensizes.

Check out the online demo abmaterial.com or download your free copy from the B4J website.  Make sure you read the included README.TXT files.  It contains some important info and shows some tips and tricks.

That’s it for now.  Next big release will be all about ABMAD. Until next time!

B4J: ABMaterial Public 1.12/Donators 1.20 now released

So, what happened to 1.09, 1.10 and 1.11?
Version 1.09 does not exist. I’ve changed it to 1.10 so I can use the major number as the main release update and the minor number for maintenance releases. e.g. maintenance releases for 1.10 are 1.11,1.12, etc… The next big release is 1.20.

Highlights of the releases:

All components are fully dynamic

In a ‘static’ page, all the components are written in the .html file. In a ‘dynamic’ page they are not. Only when you connect as a user, the components are inserted in their browser.

This seems trivial, but this actually means we can ‘write’ components (html, css and javascript) at run-time, depending on e.g. the user that logged in. Some user is allowed to see one chart, another user another chart. Or one may be able to delete a record from your database, another is not. Or showing a certain modal sheet depending on the user without having to add all possibilities in the HTML. Or show the page in different languages depending on who logged in!

New component ABMTimeLine

ABMTimeline is a component to present a time line of events. Using the ABMTimeLineElement you can create events, with some assets like images.

abmaterial-abmtimeline

New component ABMFlexWall

ABMFlexWall is a simple galarie component for images.  Together with the IsMaterialBoxed=true setting, it creates an easy to use image wall.

abmaterial-flexwall

Speed, the need for speed…

Following all the guidelines of Google, ABMaterial is one of the fastest framesworks around.  Not only in time of development, but this is certainly the case for the user experience. And all done in the background for you!

googletest

Firebase Auth and Storage support (1.20)

ABMaterial is always on top of new technologies.  Latest in line is support of Googles Firebase API. You can use Firebase Auth to login to your ABMaterial (1.20) WebApp and with Storage, you can upload/download files with ease. Together with B4X Firebase support, you can build the most powerful apps ever.

New components ABMSVGSurface, ABMFileInput, ABMTableMutable and ABMPatternLock (1.20)

Always on the move, new components are introduced with every release.  Donators can find more info on these new components in their mail.  More on this blog when 1.20 is released to the public.

So check out the online demo abmaterial.com or download your free copy from the B4J website

Until next time!
