[cdt-dev] Refreshing project properties (again)

[Branko Drevenšek <branko.drevensek@xxxxxxxxx>]

Hi, cdt-dev.

I have custom GNU based toolchain properly defined through 
buldDefinitions extension point. As our compiler has a bunch of CPU 
specific options, I'd like to simplify setting these for users. I have 
few custom property page(s), where user can select things like, for 
example, CPU endianness, and this then offers user to automatically 
modify all corresponding toolchain options.

For start I tried to automatically reconfigure compiler switches on 
project (no folder/file specific settings yet). I search for appropriate 
options through configurations and modify them, similar to what's 
described here: 
http://dev.eclipse.org/mhonarc/lists/cdt-dev/msg11166.html. This works, 
but if CDT tab (like ToolSettingsTab) has already been displayed, it 
will show old values. Closing project properties and reopening it shows 
modified values. Also if "C/C++ build" / "Settings" page has not been 
shown yet, proper values will be shown, when user opens it.

Calling ManagedBuildManager.saveBuildInfo or 
CoreModel.getDefault().setProjectDescription makes no difference. I 
tried to tell property pages to refresh by using AbstractPage.informAll 
( ICPropertyTab.UPDATE... ), but this is not really it (does not work, 
does not seem to be intended for that purpose).

Can somebody give me some hints what needs to be done so 
programmatically set properties can be seen immediately? I guess dialog 
shows some cached view, but how to make it refresh?

Thanks.
Branko
