当我在toUseExplorerTheme
中使用TVirtualStringTree.PaintOptions
时,它会像这样绘制选区:
请注意,选择范围从控件的左侧延伸到任何节点标题的最右侧范围的位置;选择的宽度都相同。
我希望它看起来像这个图像(someone else's project,使用Virtual TreeView),其中选择仅涵盖节点标题的文本:
除非Virtual TreeView中有回归(我使用的是5.2.2),否则这一定是可能的,但我找不到合适的选项组合。
这是我的设置代码:
fTree := TVirtualStringTree.Create(Self);
fTree.Parent := Self;
fTree.Align := alClient;
fTree.OnGetText := TreeGetText;
fTree.OnInitNode := TreeInitNode;
fTree.OnInitChildren := TreeInitChildren;
fTree.OnChange := TreeSelectionChange;
fTree.RootNodeCount := 1;
fTree.DrawSelectionMode := smBlendedRectangle;
fTree.TreeOptions.PaintOptions := fTree.TreeOptions.PaintOptions
+ [toUseExplorerTheme];
fTree.TreeOptions.SelectionOptions := fTree.TreeOptions.SelectionOptions
+ [toMultiSelect];
答案 0 :(得分:6)
抱歉,that was my fault
。我在this issue
中建议的陈述应该是:
procedure DrawBackground(State: Integer);
begin
// if the full row selection is disabled or toGridExtensions is in the MiscOptions, draw the selection
// into the InnerRect, otherwise into the RowRect
if not (toFullRowSelect in FOptions.FSelectionOptions) or (toGridExtensions in FOptions.FMiscOptions) then
DrawThemeBackground(Theme, PaintInfo.Canvas.Handle, TVP_TREEITEM, State, InnerRect, nil)
else
DrawThemeBackground(Theme, PaintInfo.Canvas.Handle, TVP_TREEITEM, State, RowRect, nil);
end;
这同样适用于下一个嵌套过程DrawThemedFocusRect
。修复程序现在已提交到revision r587
,因此请更新您的虚拟树视图。感谢@joachim的合作!
