[ABMaterial] Mini Template for absolute beginners
[ABMaterial/ABMServer] Mini Template for absolute beginners (update 2024/05/17)
Hi all, Since the lockdown everywhere, a lot of B4X users seem to want to learn ABM to make WebApps in B4J. That is great! :) However, some seem to struggle a lot to get started. I understand, as even opening up the template can be quite overwhelming with those Cache, Root, Page etc classes...

On the surface, ABMaterial appears to be a complex framework - which in fact, it is. However, through the series of specific topics (new posts), we will expose how easy it is to use - and construct beautiful / functional web apps.
The first post in this series (ok, the second) will have a complete project based on @alwaysbusy (empty) Template project included in each version he releases. It shall use ABM version 4.03 which is available to everyone. This well documented example will expose the Template page (populated with controls), a simple About page and the ABMShared code module containing the navigation bar and component themes. This is generally enough to get a newcomer started - since it actually does something!
We encourage others who are proficient with ABM to contribute well documented examples to this tutorial. Usually, this will be in the form of a stand alone "page" that can be added to the project, and any support methods needed which should go into the ABMShared code module.
For the pupil, he/she will download your .bas and add it to the project, create a menu item in the nav bar, add requirements in Main to initialize and any methods for ABMShared.
Many lessons (new posts) will be added with simple sections - as not to over-complicate matters.
Here is a small sample of what to expect:
B4X:
public Sub ConnectPage()
' connecting the navigation bar - now that we have built one above...
' examine the code in ABMShared to see how this works...
ABMShared.ConnectNavigationBar(page)
' Let's add some components to the page - labels (with text), buttons and other controls...
' page.Cell(1,1).AddComponent(ABMShared.BuildLabel - here we add a label component to Row 1 / Cell 1, using a single statement
' and a method found in ABMShared Code Module.
' page.Cell(1,1).AddComponent(ABMShared.BuildLabel(page, "basic1", - each component MUST have a Unique ID ("basic1" in this case)
' Notice that the text is right-justified... How??? Using a theme - "lbltheme1"
' I will let you discover what the other parameters are for this method...
page.Cell(1,1).AddComponent(ABMShared.BuildLabel(page, "basic1", "See the faint green dot above in title bar? This means your websocket is connected! {BR} All of this page's code is explained in the source file! {BR}{NBSP}", ABM.SIZE_H4, "lbltheme1", 0, "25px"))
' Here we add another component in Row 2, Cell 1 - It is essentially a label with block quote
page.Cell(2,1).AddComponent(ABMShared.BuildParagraphBQWithZDepth(page, "basic13", "Hi There! I am in Row 2 of this page! {BR}{BR} I Have 'Flow Text' Applied. What does that mean? Resize this browser window and watch THIS text size shrink and grow accordingly!" ))
' Lets do something different in Row 3...
'.............................................The second post will have a link to download the base project - since it is much too large to attach here.
Thanks
