如何在保留所有箭头的同时消除 TreeView 中的线条 [英] How can I eliminate the lines in TreeView while keeping all arrows

问题描述

我有一个 TreeView，我正在使用 SetWindowsTheme() pinvoke 对其进行蒙皮，但是我无法删除出现的树线.

I have a TreeView which I am skinning using the SetWindowsTheme() pinvoke, however I am unable to remove the tree lines that appear.

我不想画所有者"，因为我认为这相当于用一辆 18 轮卡车运送一个炸玉米饼(矫枉过正).

推荐答案

试试这个:

Not sure if this will show up as you wish under your theme, though.
