Hi.
I made a patch to fix bugs.
Please review it.
Best regards.
Kazuki Oikawa
StatusBar.cs
- SizingGrip area should not be allocated when it is not displayed.
- Now it reflects MinWidth of the containing panel and fixed a crash that
happens when its width becomes so small.
ListBox.cs
- Items should be fully shown.
- When resizing and vertical scrollbar disappeared, the item of index 0 should
be on the top of the list.
- GetItemRectangle should consider the size of vertical scrollbar.
ThemeWin32Classic.cs
- Fixed a bug that ListBox items were wrapped at the right end.
ComboBox.cs
- When DropDownStyle is Simple, it does not show scrollbar to the last item of
the list.
- When DropDownStyle is Simple, it crashed when the list was scrolled down with
the down cursor key.
- Fixed a bug that when DropDownStyle is DropDownList, the selected item was
not shown.
- The position of the selected item was not preserved when the next dropdown
happened.
CheckedListBox.cs
- (Fixed #1 of CheckedListBoxTest.CheckedListBoxPropertyTest.)
Tooltip.cs
- Fixed #Mtd2 of ToolTipTest.RemoveToolTipTest.)
