Is it possible to have multiple header rows in a virtual string tree?
I have a need for multiple fixed rows for the header of a virtual string view - something that looks like the effect you get if you set a StringGrid
's FixedRows
property to a value greater than 1. Is there a way to achieve this?
Some searching on the Soft-Gems website and forums led me to a couple of mentions of an AdvancedHeaderDraw
method and a HeaderQueryElements
property on the virtual string tree, but I can't work out how to use them.
I also found a demo that uses THeaderControls
to achieve a similar effect but there has to be a more elegant solution.
AFAIK并没有像这样内置的东西。但是你可以尝试在这个页面上标记为“Virtual Treeview desc。(嵌套头文件)”的VT后代。
