B4X: Responsive containers in ABMaterial 4.25

ABMDragonfly4.00

Next to the normal responsive page behaviour, in ABMaterial 4.25 for B4J, you will be able to do this with containers too!

Let’s watch it at work first:

This may not sound super special, but it’s a biggie! There are very few frameworks out there that can do this, so I’m very proud of this one.

Nice but that must ask for a lot of control code, no?“, I hear you ask.
Well, here it is:

gridContainer.IsResponsiveContainer = True

Done! 🙂

Just by setting gridContainer.IsResponsiveContainer = True, you just made the ABMContainer device responsive just like a page. This means you can from now on actually create controls that behave differently depending on the device you are on.

For example, setting this grid on a container, the last 5 cells will wrap differently on a phone, tablet or desktop:

gridContainer.AddRows(1,True,"").AddCells12(1,"")
gridContainer.AddRows(1,True,"").AddCells12(1,"")
gridContainer.AddRows(1,True,"").AddCellsOSMP(5,0,0,0,12,6,4,0,0,0,0,"")

I also added some powerful tools to adjust the layout of your WebApp according to the device you are on:

Page.GetCurrentPageSize:
Returns the current page size (phone, tablet, desktop). You can use this method e.g. in ConnectPage to determine the state of the current page size and act accordingly.

public Sub ConnectPage()
   Log("Current page size: " & page.GetCurrentPageSize)
   ...
End Sub

An event Page_SizeChanged will return the same value in the ‘current’ parameter if the user changes the window size. (It also returns the ‘previous’ state).

Note that this event is NOT raised at load time! Use Page.GetCurrentPageSize to check that.

Sub Page_SizeChanged(previous As String, current As String)
   Log(previous & " -> " & current)
   Select Case current
       Case "phone"
           gridContainer.MarginLeft = "0px"
           gridContainer.SetFixedWidth("100%")
       Case "tablet"
           gridContainer.MarginLeft = "210px"
           gridContainer.SetFixedWidth("calc(100% - 210px)")
       Case "desktop"
           gridContainer.MarginLeft = "210px"
           gridContainer.SetFixedWidth("calc(100% - 610px)")
   End Select
   gridContainer.Refresh
End Sub

Containers on a fixed position:
Next to setting a fixed with and height of an ABMContainer, you can now also set a fixed position. This can be handy to create ‘floating’ sidebars for example.

compContainer.SetFixedPosition("0px", "", "56px", "")

Params: left, right, top,bottom

Set a parameter to empty string when you don not want to set it.

These 3 new features used together give you an immense power over how your WebApp should behave depending on the device it is running on, with very little effort.

Another year has passed:

2017 has been a great year for B4X and ABMaterial!

B4X has grown to be a very powerful player in develop land.  The already productive RAD IDE has received a couple of very innovative features to help you even more with your app development. Anywhere Software is always right on top of all the new stuff Android, iOS and all the other supported platforms throw at us.  And being stable and reliable makes this a unique environment. The growth of the forum and the quality of the messages/responses are the real proof of this.  Thanks a lot Erel for this beautiful tool.  It is without a doubt the best cross-platform tool one can use for the moment!

And ABMaterial is lucky to be able to stand on the shoulders of this giant.  ABM has surpassed my biggest expectations this year.  It is great to see a lot of you are using it to make amazing webapps and even can make a living out of it.  This was definitely the ‘year of speed‘.  Very few frameworks can match ABM when it comes to develop and execution time. And there is a lot more in the pipeline for the upcoming months!

Thank you all for following my blog!  You inspire me every day to push the limits of the tools and frameworks I make.

Rest me only to wish you all the very best and I hope to see you back in 2018!

B4X: Custom Icons in ABMaterial 4.25

customicons

A much asked feature has been to integrate custom icons in ABMaterial for B4J. In version 4.25, this will be possible!

Couple of notes first:
1. The already build-in font icons (font awesome, google icons) are a lot faster to load, so consider them first
2. Some basic CSS knowledge will be needed (margins, padding, fill)
3. Custom icons MUST be named starting with abm-

There are three ways to load custom icons in ABM:

1. SVG
These type of icons MUST be loaded in BuildPage. This is because, when used, they link to the SVG tags (contrary to embedded SVG, see further). If used multiple times, it will make your HTML code smaller as the SVG code is only included once in the HTML.

page.AddSVGIcon("abm-si-maki-basketball-11", $"<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" style="width:0;height:0;position:absolute;overflow:hidden;">
     <defs><symbol viewBox="0 0 11 10.54083251953125" aria-labelledby="basi-maki-basketball-11-title" id="abm-si-maki-basketball-11"><title id="basi-maki-basketball-11-title">icon basketball-11</title><path d="M11 1a1 1 0 1 1-2 0 1 1 0 0 1 2 0zM4.5 3a1.5 1.5 0 1 0 0-3 1.5 1.5 0 0 0 0 3zm3.89 6.69L6 6.59V4.5h.5a.49.49 0 0 0 .41-.23l1.5-2A.49.49 0 0 0 8.5 2a.5.5 0 0 0-.86-.34L6.25 3.5H2.5a.5.5 0 0 0-.36.16l-2 2.54a.49.49 0 0 0-.14.3.5.5 0 0 0 .5.5.49.49 0 0 0 .41-.23L2.74 4.5H3v2.09L.61 9.69a.5.5 0 0 0 .39.81.49.49 0 0 0 .41-.23L3.94 7h1.12l2.52 3.27A.5.5 0 0 0 8.5 10a.49.49 0 0 0-.11-.3v-.01z"/></symbol> </defs>
   </svg>"$, 24,24,"margin-top: 12px;fill: black")

As you can see, in here we have also to declare a margin-top and a fill color in CSS. The name for our icon is ‘abm-si-maki-basketball-11′.

Icons like this typically have an SVG tag looking like this (hidden, width & height = 0, ALL properties are required!):

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" style="width:0;height:0;position:absolute;overflow:hidden;">...</svg>

10000+ icopns of this type can be found here: https://leungwensen.github.io/svg-icon/

2. Embedded SVG
These type of icons can be loaded at runtime (e.g. in ConnectPage) as the SVG tag code will be included in the html. This also means if you use the same icon multiple times, the full SVG code will be added multiple times too!

page.AddEmbeddedSVGIcon("abm-aardbei", $"<svg xmlns="http://www.w3.org/2000/svg" height="32" width="26" viewBox="0 0 116.76708 149.28999" style="margin-top: 8px;fill: red">

  </g>
</svg>"$)

Here too, some CSS has to be used + setting the width & height too.

A typical svg tag looks like this:

<svg xmlns="http://www.w3.org/2000/svg" width="32" height="32" viewBox="0 0 1024 1024" style="margin-top: 14px;fill: black">...</svg>

Such svg tags are e.g. created when exporting it from Illustrator.

3. Images
These type of icons are just plain png/jpg images. Make sure you use the appropriate size of the image to load. e.g. if your icon is going to be 32×32, do not load a 1024×1024 image!

page.AddImageIcon("abm-batman", "../images/batman.png", 32, 32, "margin-top: 8px", "Batman")

In this case, width, height and the CSS are part of the load method.

You can find 65000+ of these icons here: https://icons8.com/

USAGE
Now you can use your loaded icons like you would load font based icons:
e.g.

Dim lblTest As ABMLabel
lblTest.Initialize(page, "lblTest", "This is some test {IC:#000000}abm-si-maki-basketball-11{/IC} with {IC:#000000}abm-aardbei{/IC} special icons {IC:#000000}abm-gmail{/IC} or {IC:#000000}abm-gmail2{/IC}.", ABM.SIZE_H6, True, "")
page.Cell(9,1).AddComponent(lblTest)

Note that the color in the {IC} tag must be set for compatibility reasons, but is ignored.

Another example is in the sidebar menu:

page.NavigationBar.AddSideBarItem("MDL4", "Batmans layer", "abm-batman", "")
page.NavigationBar.AddSideBarDivider
page.NavigationBar.AddSideBarItem("MDL5", "From icons8.com", "abm-facebook", "")
page.NavigationBar.AddSideBarDivider

Or on the action button:

Dim actionB As ABMActionButton
actionB.Initialize(page, "ActionB", "abm-aardbei-action", "", "")
page.AddActionButton(actionB)<span 				data-mce-type="bookmark" 				id="mce_SELREST_start" 				data-mce-style="overflow:hidden;line-height:0" 				style="overflow:hidden;line-height:0" 			></span>
