How to remove padding value from perspective's page layout [message #1758247]

Hi,

We use theme contribution to extend the existing RAP default theme. We have 2 perspectives to implement the login and it works well. By default when start, the login perspective is loaded, and when the user/pass credentials are processed and valid, we unload the login perspective and load the client perspective, where application module constructs are placed.

We are required to remove the padding from left panel. please find the attachment.
(the space between top, left and bottom should be removed, and this should be ok, as we don't place other views editor in login perspective).

Any idea ?

Regards,
Sudesh

If, for example, the left part of your view is a Composite, and if you have a theming css file somewhere, you can try this:

In your css file:

Composite.KeyStringOfYourChoice
{
padding: 0px 0px 0px 0px;
}

In your java file:

final Composite yourComposite = new Composite(composite, SWT.NONE);
yourComposite.setData(RWT.CUSTOM_VARIANT, "KeyStringOfYourChoice");

This will work fine for all controls whose padding values can be controlled via CSS. An excellent page for finding this out would be http://download.eclipse.org/rt/rap/doc/3.0/guide/reference/theming/index.html

I wouldn't think a theme padding value would impact the padding of a Composite. It would be a Layout creating the gap when it lays out it's child controls

Correct, composite padding didn't help here. Any idea how to fix this or workaround ?

You'll need to walk through the widget tree, find the correct composite and update the values of its layout manager.
