Questions about TreeView

[Jochen Noller]

Hello,

I need a TreeView in my application. I already studied some examples with SysTreeView32. Now I've the following open points:
- is it possible to have a TreeView where the parents are "grey-checked" as long as not all childs are checked?
- is it possible to add some kind of bars on each node (in my case I want to show the size of the childrens)
- is it possible to implement some kind of colums to the TreeView, so that each node consists not only of one element

Regards,
Jochen

To answer the first question - Yes, here's an example: http://www.powerbasic.com/support/pb...ad.php?t=23042

I'm having trouble visualising the second and third - do you have screen shots /example programs that use those techniques.?

Hello Dave,

thank you. That solves point 1. Regarding point 2: Have a look at this screenshot: http://www.jam-software.de/treesize_...reesize_gr.gif

Reg. point 3 I'll illustrate it with following example:

Root 1
>>SubNode 1 AddInfo1a AddInfo1b
>>SubNode 2 AddInfo2a AddInfo2b
>>SubNode 3 AddInfo3a AddInfo3b
Root 2
>>SubNode 4 AddInfo4a AddInfo4b
>>SubNode 5 AddInfo5a AddInfo5b
>>SubNode 6 AddInfo6a AddInfo6b
[...]

Naturally I can do this with somekind of spaces or tabs, but this is not very professional.

Regards,
Jochen

For multi-column info, instead of using a treeview control, maybe you should look at a listview control using the "indent" options.

looking at your example above, my guess is that it is done by drawing on the treeview's DC. Here is a link which may be useful should you wish to pursue that line of investigation.
