TODO:
|
|
|
|
- How TDECModuleProxy behaves wrt memory leaks and behavior, when exiting
|
|
from root mode is not tested, because no code make use of it. It needs
|
|
work, if it should be used.
|
|
|
|
- Should write a document which outlines test cases, to avoid
|
|
regressions. This class is a hazard.
|
|
|
|
- Two Layout problems in runAsRoot:
|
|
* lblBusy doesn't show
|
|
* d->kcm/d->rootInfo doesn't get it right when the user
|
|
presses cancel in the tdesu dialog
|
|
|
|
- Resizing horizontally is contrained; minimum size is set somewhere.
|
|
It appears to be somehow derived from the module's size.
|
|
|
|
- Prettify: set icon in KCMultiDialog.
|
|
|
|
- Perhaps it's possible to link against tdesu such that
|
|
the dialog is in process?
