B4X: Important upgrade to ABMaterial 4.03 for everyone!

ABMDragonfly4.00

As you probably already have noticed, the B4J IDE Project Explorer has received a major upgrade. And it is GREAT! However, ABMaterial had some trouble with the new file format, so last night I’ve been working non-stop on a fix to be compatible.

If you are using B4J 6.00+, you MUST download 4.03 or higher.  For that reason, EVERYONE (donator or not), can upgrade to the new version.

You can download the latest version of ABMaterial Dragonfly here.

Until next time!

B4X: Lightweight charts in ABMaterial

Frappe3a

The official charts library inABMaterial is Chartist, but because of its many features it is also a rather slow rendering js/css library and not always that easy to implement. On the B4X forum, Mashiane has created a nice ABMCustomComponent wrapper for the JQPlot plugin and there are many examples in the forum on how to implement Google Charts in ABM, like this post from Harris.

So why yet another one? Well the main focus on this wrapper is being fast AND easy to implement. Of course this also means less tunable features but I have found that maybe for 95% of our needs having some basic stuff like a tooltip and being clickable is actually enough.

I came accross the Frappé charts javascript library. It has tooltips, some interactions and animations. And it is bloody fast! 🙂

I only had to make a couple of CSS changes to make it ABM compatible and the ABMCustomComponent wrapper was very easy to write.

Usage:

Create your chart variables in Class_globals:

Dim FrappeChart1 As FrappeChart
Dim FrappeChart2 As FrappeChart
Dim FrappeChart3 As FrappeChart
Dim FrappeChart4 As FrappeChart
Dim FrappeChart5 As FrappeChart
Dim FrappeChart6 As FrappeChart
Dim FrappeChart7 As FrappeChart

In Page_Connect(), make your charts (you immidately can see the simplicity of the code):

FrappeChart1.Initialize(page, "FrappeChart1", "bar", "My Awesome Chart", 250)
FrappeChart1.FrappeLabels.AddAll(Array As String("12am-3am", "3am-6am", "6am-9am", "9am-12pm","12pm-3pm", "3pm-6pm", "6pm-9pm", "9pm-12am"))
FrappeChart1.AddDataSet("Some data", "light-blue", Array As Int(25, 40, 30, 35, 8, 52, 17, -4), Array As String())
FrappeChart1.AddDataSet("Another set", "violet", Array As Int(25, 50, -10, 15, 18, 32, 27, 14), Array As String())
FrappeChart1.AddDataSet("Yet Another", "blue", Array As Int(15, 20, -3, -15, 58, 12, -17, 37), Array As String())
page.Cell(1,1).AddComponent(FrappeChart1.ABMComp)

FrappeChart2.Initialize(page, "FrappeChart2", "line", "My Awesome Chart", 250)
FrappeChart2.FrappeLabels.AddAll(Array As String("12am-3am", "3am-6am", "6am-9am", "9am-12pm","12pm-3pm", "3pm-6pm", "6pm-9pm", "9pm-12am"))
FrappeChart2.AddDataSet("Some data", "light-blue", Array As Int(25, 40, 30, 35, 8, 52, 17, -4), Array As String())
FrappeChart2.AddDataSet("Another set", "violet", Array As Int(25, 50, -10, 15, 18, 32, 27, 14), Array As String())
FrappeChart2.AddDataSet("Yet Another", "blue", Array As Int(15, 20, -3, -15, 58, 12, -17, 37), Array As String())
page.Cell(1,1).AddComponent(FrappeChart2.ABMComp)

FrappeChart3.Initialize(page, "FrappeChart3", "scatter", "My Awesome Chart", 250)
FrappeChart3.FrappeLabels.AddAll(Array As String("12am-3am", "3am-6am", "6am-9am", "9am-12pm","12pm-3pm", "3pm-6pm", "6pm-9pm", "9pm-12am"))
FrappeChart3.AddDataSet("Some data", "light-blue", Array As Int(25, 40, 30, 35, 8, 52, 17, -4), Array As String())
FrappeChart3.AddDataSet("Another set", "violet", Array As Int(25, 50, -10, 15, 18, 32, 27, 14), Array As String())
FrappeChart3.AddDataSet("Yet Another", "blue", Array As Int(15, 20, -3, -15, 58, 12, -17, 37), Array As String())
page.Cell(1,1).AddComponent(FrappeChart3.ABMComp)

FrappeChart4.Initialize(page, "FrappeChart4", "pie", "My Awesome Chart", 250)
FrappeChart4.FrappeLabels.AddAll(Array As String("12am-3am", "3am-6am", "6am-9am", "9am-12pm","12pm-3pm", "3pm-6pm", "6pm-9pm", "9pm-12am"))
FrappeChart4.AddDataSet("Some data", "light-blue", Array As Int(25, 40, 30, 35, 8, 52, 17, -4), Array As String())
FrappeChart4.AddDataSet("Another set", "violet", Array As Int(25, 50, -10, 15, 18, 32, 27, 14), Array As String())
FrappeChart4.AddDataSet("Yet Another", "blue", Array As Int(15, 20, -3, -15, 58, 12, -17, 37), Array As String())
page.Cell(1,1).AddComponent(FrappeChart4.ABMComp)

FrappeChart5.Initialize(page, "FrappeChart5", "percentage", "My Awesome Chart", 250)
FrappeChart5.FrappeLabels.AddAll(Array As String("12am-3am", "3am-6am", "6am-9am", "9am-12pm","12pm-3pm", "3pm-6pm", "6pm-9pm", "9pm-12am"))
FrappeChart5.AddDataSet("Some data", "light-blue", Array As Int(25, 40, 30, 35, 8, 52, 17, -4), Array As String())
FrappeChart5.AddDataSet("Another set", "violet", Array As Int(25, 50, -10, 15, 18, 32, 27, 14), Array As String())
FrappeChart5.AddDataSet("Yet Another", "blue", Array As Int(15, 20, -3, -15, 58, 12, -17, 37), Array As String())
page.Cell(1,1).AddComponent(FrappeChart5.ABMComp)

FrappeChart6.Initialize(page, "FrappeChart6", "bar", "My Awesome Chart", 250)
FrappeChart6.FrappeLabels.AddAll(Array As String("Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"))
FrappeChart6.AddDataSet("Some data", "purple", Array As Int(25, 40, 30, 35, 8, 52, 17), Array As String())
FrappeChart6.AddDataSet("Another set", "orange", Array As Int(25, 50, -10, 15, 18, 32, 27), Array As String())
FrappeChart6.FrappeShowSums = True
FrappeChart6.FrappeShowAverages = True
page.Cell(1,1).AddComponent(FrappeChart6.ABMComp)

FrappeChart7.Initialize(page, "FrappeChart7", "bar", "My Awesome Chart", 300)
FrappeChart7.FrappeLabels.AddAll(Array As String("Ganymede", "Callisto", "Io", "Europa"))
FrappeChart7.AddDataSet("Distances", "grey", Array As Int(1070.412, 1882.709, 421.700, 671.034), Array As String("1.070.412km", "1.882.709km", "421.700km", "671.034km"))
FrappeChart7.FrappeIsNavigable = True
FrappeChart7.FrappeRaiseEventOnClick = True
page.Cell(2,1).AddComponent(FrappeChart7.ABMComp)

An example of the Click event on Chart7:

Sub FrappeChart7_Clicked(index As Int)
   Dim img As ABMImage = page.Component("img")
   Dim lbl As ABMLabel = page.Component("lbl")
   Select Case index
     Case 0
       img.Source = "../images/ganymede.jpg"
       lbl.Text = "{B}Ganymede{/B}{BR}{BR}Semi-major-axis: 1070412 km{BR}{BR}Mass: 14819000 x 10^16 kg{BR}Diameter: 5262.4 km"
     Case 1
       img.Source = "../images/callisto.jpg"
       lbl.Text = "{B}Callisto{/B}{BR}{BR}Semi-major-axis: 1882709 km{BR}{BR}Mass: 10759000 x 10^16 kg{BR}Diameter: 4820.6 km"
     Case 2
       img.Source = "../images/io.jpg"
       lbl.Text = "{B}Io{/B}{BR}{BR}Semi-major-axis: 421700 km{BR}{BR}Mass: 8931900 x 10^16 kg{BR}Diameter: 3637.4 km"
     Case 3
       img.Source = "../images/europa.jpg"
       lbl.Text = "{B}Europa{/B}{BR}{BR}Semi-major-axis: 671034 km{BR}{BR}Mass: 4800000 x 10^16 kg{BR}Diameter: 3121.6 km"
   End Select
   img.Refresh
   lbl.Refresh
End Sub

B4X: ABMaterial 3.75 Public/4.00 Donators released

ABMDragonfly4.00

ABMaterial Dragonfly (4.00) for B4X is available. Yes, it has a new name! What started as version 3.81 got upgraded to a new major version, especially since it uses a new cache control system.

ABMaterial has always been one of the fastest RADs from its start, now over 2 years ago.  But with 4.00, we’ll take it to a whole new level!

Mindful and I have spend 5 days (and nights) checking out how we could cache ABMaterial to the extreme without losing any of its functionality.  The results are just ridiculous…

Finish times are less than 10% of the time on the second and next loads. So on 3G, on the users next visit(s), the WebApp is almost just as fast as on high speed cable!

And this system not only works with the same page. Once one page has been loaded, all the other pages can take gain of this system. Even when the user revisits your app much later.

Furthermore there is the new debug feature to check how your apps work on different device sizes.  See it at work here:

Add this snippet to you main module, AFTER starting the server:

#If DEBUG
' in debug mode, start the browser and open the app on all devices (DOES NOT WORK IF EDGE IS YOUR DEFAULT BROWSER!)
ABM.ViewerOpenAllDevices("http://localhost:" & port & "/" & ABMShared.AppName & "/", 100)

' or open a specific device as default (DOES NOT WORK IF EDGE IS YOUR DEFAULT BROWSER!)
'ABM.ViewerOpenDevice("http://localhost:" & port & "/" & ABMShared.AppName & "/", 300, ABM.VIEWER_TABLET)

' or just open de browser, no multiple devices (should work in Edge)
'ABM.ViewerOpen("http://localhost:" & port & "/" & ABMShared.AppName & "/")
#End If

Lots of new theme properties! Check out the demo on how to use  them in the new Dragonfly theme.  As winter is coming and days are getting shorter (at least here in the northern hemisphere), I went for a ‘Night’ theme this time.

ABMaterial DragonFly is now available on 750+ locations worldwide on CDN!  If you use the CDN, you do not need to upload the css/js/fonts folders to your own server anymore!

This means only your own assets (images etc) from the www folder have to be available on your server. De demo running on abmaterial.com for example is working like this.

Usage:

ABM.ActivateUseCDN("DONATORKEY", "https://cdn.jsdelivr.net/gh/RealAlwaysbusy/ABMaterial@v4.03/")

The over 20 new fixes and fulfilled wishes make ABMaterial 4.00 very stable, just like its ‘parent’ programming language: B4X.  It is a real joy knowing one can depend on a strong, bug free environment.  Erel from Anywhere Software rulez!

Happy programming!
