Auto-resizing fixed docks

Hello,
I’m try to implement a new file chooser dialog after the KDE4 file chooser dialog.
The left panel with the places is a dock, so I want to use Docking Frames to do the same.
So far so good, but one difficulty: if I resize the dialog, then the bottom Dock is getting bigger and the user must adjust the sizes.

The question is: is it possible to fix the size of the bottom Dock (Dock C) so that if the dialog is resized only Dock A and Dock B are resized?

Attached are some screenshots and the docking code.

Thank you.

AbstractCDockable has a method setResizeLocked, with which you can instruct the framework not to resize the Dockable if possible.

Note that this will not prevent the user from manually resizing the Dockable, nor will it prevent the framework from resizing the Dockable if there is not enough space to properly show the contents of the dialog.

Thank you, perfect.
