Subject: [PATCH] fdo#46071: Do not hide windows based on nil "Visible"
|
|
property
|
|
|
|
This appears to be messy: The /org.openoffice.Office.Views/WindowType
|
|
configuration group template has both a nilable bool "Visible" property and a
|
|
UserData/Data string property that encodes various things like geometry---but
|
|
also visibility---in a string.
|
|
|
|
Now, likely due to the problem that has meanwhile been fixed through
|
|
f3f79cc9e6c265baf48955d53f7e888205e0b3e0 "Resolves fdo#46074: Fix
|
|
Partial::contains for paths that go past a leaf node," some
|
|
registrymodification.xcu files in the wild contain such WindowType entries in
|
|
"default" state, without a UserData/Data string and with a nil "Visible"
|
|
property.
|
|
|
|
The way SfxChildWindow::InitializeChildWinFactory_Impl and
|
|
SvtViewOptions::IsVisible are implemented, they will always lead to an invisible
|
|
window for such broken registrymodification.xcu data (as IsVisible unhelpfully
|
|
returns false for a nil value, and InitializeChildWinFactory_Impl uses that
|
|
value when there is no UserData/Data string).
|
|
|
|
For the Math formula editor window (ID 30378) this means that it can disappear
|
|
from the UI completely, as there appears to be no UI trigger for the user to
|
|
show it in case it is hidden.
|
|
|
|
The fix is to introdue SvtViewOptions::HasVisible (which only returns true if
|
|
the property is not nil) and change InitializeChidlWinFactory_Impl to only use
|
|
the value of IsVisible() if HasVisible() returns true. This makes the code even
|
|
more baroque, but this is a rather central, generic piece of code for all sorts
|
|
of windows, so I do not want to break any other uses by e.g. changing IsVisible
|
|
to return true for a nil property.
|
|
|
|
