How to specify default fonts in an RCP app [message #507392]

Hi, I'm trying to change some of the default fonts in our rcp app: For
example "org.eclipse.jface.dialogfont" (aka JFaceResources.DIALOG_FONT).
How can I ship our application with a different default dialog font?

I have tried this:
In plugin_customization.ini having an entry like this works:
org.eclipse.ui.workbench/org.eclipse.jface.dialogfont=1|Papy rus|13.0|0|COCOA|1|Papyrus;

But the format for the value seems to be undocumented (if not, can you
give me a pointer?). Is it safe to use it? How can I set different fonts
for different platforms?

Is it better (or even possible) to use code (in
WorkbenchAdvisor.preStartup() for example) to set the defaults?

Is there a way to define these fonts through extension points? I have
looked at the org.eclipse.ui.themes extension point but do not
understand how to overwrite a definition from another plugin.

Thanks for any help
Peter

Hi Peter

I have used the following to get font definitions into my RCP app. These were to define fonts for appplication parts and not to override defaults. I used the WorkbenchWindowAdvisor, you might have to use the WorkbenchAdvisor to be earlier in the cycle.

In a 'branding' plugin, I defined a default theme:
<theme
id="uk.co.rcp.ui.branding.theme"
name="RCP Theme">

In my plugin_customization.ini I specified this as the default theme:
# Workbench CURRENT Theme (see extension-point: org.eclipse.ui.themes
org.eclipse.ui/CURRENT_THEME_ID=uk.co.rcp.ui.branding.theme

In my case, I used the constructor of the WorkbenchWindowAdvisor to get the theme and values that I wanted:

ITheme currentTheme = PlatformUI.getWorkbench().getThemeManager().getCurrentTheme( );

Font details can then be obtained using:
currentTheme.getFontRegistry().getFontData(<symbolicName>);

Regards, John

Thanks John

I re-read the explanation of the <theme> element and saw that its
purpose is exactly to overwrite defaults for fonts and colors. What kept
me from using it in the past was that the value attribute seemd not to
allow platform specific overrides, but I have now seen that a
<fontOverride> element allows many <fontValue> elements where one can
specify platform specific fonts.

Regards,
Peter

"I re-read the explanation..."
I often do that - and more than once - sometimes I get it and sometimes I don't ! Smile
