FitLayout and 100% height

[neolitec]

Hi,

I have a problem when trying to apply a 100% height to a widget (a LayoutContainer in this case).
This LayoutContainer has a FitLayout layout and it's contained in a GWT widget with a height of 100% (depending on the window height).
Since the parent widget has no layout, I've fixed its height at 100%.

Now I have a FitLayouted LayoutContainer ^^ with a height of 100%.
Step 1 : success !

Now I want to add a simple ContentPanel in this LayoutContainer.
According to the documentation, the ContentPanel should take the size of the layout's container, i.e. 100%.
But that takes 100 pixels invariably.

Step 2 : fail !

2 questions :
- Is that problem due to the fact that I specified height in percent and not in pixels ?
- Is there a workaround ? (bonus : is it not recommended to mix GWT and GXT items ?)

Another one : why 100 pixels ??

Here is an piece of the source :

public class MyWidget extends LayoutContainer {
	
	protected void onRender(final Element target, final int index) {
		super.onRender(target, index);

		FitLayout layout = new FitLayout();
		setHeight("100%");
		setLayout(layout);

		ContentPanel cp = new ContentPanel();
		add(cp);
	}

}

Thanks !

Instead of setting a size by hand, especially when using percentage sizes, you should use the layoutsystem to size your widgets. Were do you add your MyWidget class? Why do you wrap a ContentPanel inside a LayoutContainer with a FitLayout?

No, the parent widget is not a LayoutContainer neither a ContentPanel, it's a GWT Composite... so I can't use the layout system.
And that's why a asked this question : is it not recommended to mix GWT and GXT items ?

I agree with you, including a ContentPanel inside a LayoutContainer with a FitLayout is simply . In fact, the goal is to include a west and a center region with a BorderLayout... the ContentPanel simplifies the problem.
I tried to replace FitLayout directly with a BorderLayout but it doesn't work : even if the BorderLayout is "100% capable", the included ContentPanels (for west and center region) take no height when I specify nothing, and 100px when I specify 100% !

I thought GXT was able to resize widgets inside pure GWT widgets but obivious it can't (.
