This fixes an issue where the FileListComponent might fail to select a
file, because the file list reported that it was still loading during
the final ChangeListener callback.
When using RDP to access a Fedora machine running Gnome, the only
available colourmap is 32-bit. The old implementation caused GUI apps to
crash when they attempted to use a null colourmap pointer.
A regression was introduced in d564e4931. Before that commit you
could use key up to jump into position zero of a multiline TextEditor
if the cursor was somewhere in the first line. Since that commit the
keypress had no effect. This change restores the earlier behaviour.
When using Universal Control, the system seems to translate mouse scroll
events into swipe gestures, meaning that the gesture position is not
constant during the gesture.
Until this commit Items with a size of 1 could be rounded to
bounds with a size of 0 or 2 due to floating point errors, leading
to slightly too large or disappearing items. The new approach
preserves the size of items.
This commit fixes an issue when using large lineSpacing, where the caret
would jump to the end of the previous line when clicking between lines.
With the new behaviour the line spacing is considered to belong to the
previous line.
The commit also changes the behaviour observed when clicking in the
empty space before the first line. Until now the caret would jump into
the first character position. Now it behaves as if the space before the
first line would belong to the first line.
This fixes an issue where opening a FileTreeComponent could cause the UI
to hang. The call to subcontentsList->isStillLoading() in
FileListTreeItem::selectFile() would always return true because the
file-scanner TimeSliceThread wasn't started until the selectFile() call
finished.
The previous implementation would trigger assertions in
grabKeyboardFocus() when the DragImageComponent was hidden due to the
target returning false from shouldDrawDragImageWhenOver().
Hiding the image would also mean that its keyboard focus was lost. Now
focus is restored when the image becomes visible again.
The warnings are only silenced in code that is conditionally used on
older platforms. When the newer (non-deprecated) API is available, it
will be used.
Prior to this commit it was possible to get the menu bar deactivated
by moving the mouse to an adjacent menu item and then back again. If
the movement was quick enough the corresponding PopupMenu would be
dismissed and created again before the dismissal's async command
handler would run. The command handler would see that the dismissed
menu's index and the currently activated index are equal and
deactivate the menu bar.
