Right-aligning background image in SWT Text [message #909757]

Hi,

I have a text box that I want to put an image as the background of a Text widget.The image has to be right-aligned, i.e. show up on the far right inside the Text widget.

Desired behavior: index.php/fa/11416/0/

I tried the following CSS setting but I see the image repeatedly shown up in the Text widget area.

Behavior now: index.php/fa/11415/0/

Text.search {
    background-image: url( icons/icon_search.png ) no-repeat right center;
}

I know the "no-repeat" and the right center attributes are not documented in the Eclipse documentation. If I don't remember incorrectly, this is how to do it with CSS. Is this behavior supported by RAP? Is there any alternatives that I can try within the boundary of RAP?

Thanks,
Ronald

Hi Roland,
in RAP 2.0M1 we added support for SWT.ICON_SEARCH flag in Text widget. See:
http://www.eclipse.org/rap/noteworthy/2.0/?build=M1
Best,
Ivan

OMG Ivan.

"SWT.ICON_SEARCH and SWT.ICON_CANCEL support for Text widget" is exactly what I need in RAP 1.5. Is there a way I can accomplish that within 1.5? We can't possibly move to 2.0 before shipping our first release.

Thanks,
Ronald

Ronald,

As a workaround, you can add a separate composite to hold your icon. Add both the text field and image to a wrapper composite and use absolute positioning to put the icon on top of the text widget. You may need a resize listener to make sure they get adjusted if your layout can be resized. Or you could put them side by side if that is acceptable.

Hope that helps,

Cole

Thanks Cole for the workaround. It does seem like this is the best option for now unless the 2.0 feature gets back-ported.

New features won't be backported, only bugfixes. That's our policy to
guarantee that upgrading to a service release involves minimal risk.
