Window Builder Custom Toolkit [message #758184]

Hi,

I'm in the process of creating a new window builder UI toolkit for a custom ui library i wrote (My UI Toolkit should use the XML window builder model so equivalent to the UiBinder GWT plugin)

So i created a new eclipse plugin extending the main wb extension points and provided the following sample model and corresponding edit parts:

1- PanelInfo, PanelEditPart and PanelFigure for a panel object
2- ButtonInfo, ButtonEditPart and ButtonFigure for a button object

In these classes, i've implemented all the necessary methods (createFigure, getModelChildren, refreshVisuals, etc ...)

Then in my design page parser class, i built a PanelInfo object and added to it two ButtonInfo objects using the addChild method:

PanelInfo panelInfo = new PanelInfo(editorContext, panelInfo.createComponentDescription(editorContext), PanelInfo.createCreationSupport());

ButtonInfo buttonInfo = new ButtonInfo(editorContext, ButtonInfo.createComponentDescription(editorContext), ButtonInfo.createCreationSupport());

ButtonInfo buttonInfo1 = new ButtonInfo(editorContext, ButtonInfo.createComponentDescription(editorContext), ButtonInfo.createCreationSupport());

panelInfo.addChild(buttonInfo);

panelInfo.addChild(buttonInfo1);

return panelInfo;

The problem i'm having is that only the panel object is being correctly displayed and not the buttons (The buttons appear as a black very small square on the panel top left edge).

If in my parser class, i only return a ButtonInfo object, that button is correctly displayed.

Could you tell me please what's wrong and how to fix this?

Thank you.

Most probably your Button models don't have any bounds.
See
org.eclipse.wb.internal.core.xml.model.AbstractComponentInfo.setModelBounds(Rectangle)
org.eclipse.wb.internal.core.xml.model.AbstractComponentInfo.setBounds(Rectangle)

If you don't know how to create Eclipse plugins and what is extension point, you need to learn this first.
This book or Eric Clayberg is very good one.

Thanks to your answer and for the book Wink

I created the plugin with the extension point but I didn't see it in windowbuilder setting (UI Toolkits).

I look to your book, thanks.

To which extension point did you create contribution?
WindowBuilder has quite a lot of them Smile

What kind of UI Toolkit do you want to support?
Something Swing based?

Look on some simple plugins which add support for non-standard Swing layout. Even if you want to support not layout, but component, this will give you idea, how to create custom model.

org.eclipse.wb.swing.MigLayout

My UI Toolkit is not based on Swing, SWT or GWT, it's completly independent.

Actually, I have a project with my own UI Toolkit. Then, I created some Widgets, Composites, etc. To facilitate the programation, I want to use a palette to generate the codes of th GUI.

So I want to create a plugin depends of windowbuilder.

For example, I have a project where I want to add a palette. So I select new Project Palette, I enter my project in the first section, but in the second section my UI Toolkit doesn't appear.
You know wich extension point is concerned?

Thaks for your time

PS: Where I can find a complete documentation on windowbuilder pro?

Well, if your toolkit is really completely independent, then you will need to do a lot.
You will need to copy some toolkit, such as Swing and make changes to work with your toolkit.
I can not say why you don't see your toolkit in wizard - too much possible problems.
At first you would need to implement IToolkitProvider and register it in plugin.xml file.

	<!-- ======================================================== -->
	<!-- Toolkit -->
	<!-- ======================================================== -->
	<extension point="org.eclipse.wb.core.toolkits">
		<toolkit id="org.eclipse.wb.swing">
			<provider class="org.eclipse.wb.internal.swing.ToolkitProvider"/>

We don't have any other developer documentation that you can already find.
