How to style View header? [message #900085] Fri, 03 August 2012 21:26 Go to next message

Hello,

I am trying to style the ViewPart Tab header. Which widget should I be theming?

http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.rap.help%2Fhelp%2Fhtml%2Freference%2Ftheming%2Findex.html

I tried TabItem and CTabItem but the colors don't change. I can change the Shell-Titlebar style but it changes the title bar of all shells (include the TitleAreaDialog).

Any pointers are greatly appreciated!

Ronald

These are usually CTabItems, unless you are using a custom look and feel
(e.g. "buisness" or "fancy" from budle org.eclipse.rap.design.example),
in which case you need to look here:

To change the style of specific widget-instances, you need to use custom
variants:

Roland,
please note that Workbench has it's own theming capabilities which could
override the RAP theming. See DefaultTabFolder and PaneFolder classes.
Best,
Ivan

Hi,
a fast web search for "Eclipse Workbench Theme" brings me to this article:

Ivan,

Thanks for the link but I am trying to keep all my settings in CSS. After trying the CTabItem style,

CTabItem {
    font: normal bold 15px Trebuchet, Arial, sans-serif;
    color: #ffffff;
    background-color: #005596;
    background-image: none;
    padding: 10px 25px;
    spacing: 0px;
    text-shadow: none;
}

CTabItem:selected {
    color: #005596;
    background-image: gradient(linear, left top, left bottom,
            from( #0000ff ),
            color-stop( 10%, #ffffff) ),
            to( #ffffff )
        );
}


It seems like RAP honors the font, padding, spacing, and text-shadow without a problem. However, "color", "background-color", and "background-image" are not being honored.

I have attached how the UI renders when the tabs are being selected with the code above.

Thanks,
Ronald

Roland,
that's true, because these properties are overrided by the Workbench
theme - set background, background (selection) gradient by code. If you
search somewhere in the DefaultTabFolder or PaneFolder classes you will
find the places where these properties are set. In RAP, the properties
set by the code always override the same properties set by RAP theming.
HTH,
Ivan

Ivan,

I understand that the code will override CSS settings, but is it a desirable behavior? With this limitation, developers are pretty much handcuffed by whatever colors that the code is using, and the color may not go along with the rest of the CSS settings we set for other components. Is there a way to relax it, or is it a big fix that there is no hope to get in 1.5.1 time frame even if a bug is logged?

Thanks,
Ronald

Roland,
currently there is no workaround. If a property is set by the code it
takes precedence. From my point of view this is not a bug (this is how
workbench theming works) and there is no chance for improvement in this
direction for 1.5.1. Sorry.
Best,
Ivan
