TTreeView HotTrack?
« on: September 27, 2013, 10:21:12 pm »
How can I get the Treeview to show a handpoint cursor and underline the node the mouse is above?

I have a lot of treenodes and it would make navigating the tree a bit more friendly to the user. Imagine a hyperlink in your webbrowser, I would like the same for treenodes in a TTreeview. I thought Hottrack would do it but for me it does not seem to do anything.

Thanks.

Turning on the Option tvoHotTrack (or just setting HotTrack to true) underlines the node underneath the mouse. Not sure about the hand cursor, though.

Been a few years since I was on Linux, but HotTrack was not implemented on GTK2.  Which OS are you on?

Excellent :-)   But I was actually asking the OP, as he was the one with the Hot track issues.  I suspect he's trying with the GTK2 implementation.

Problem is not in LCL  but in Gtk2.

Tried in Windows running Lazarus v1.0.12 also and does not seem to be working :-\

Tested in a new empty project, added a treeview and added nodes at designtime, turned Hottrack on and tvoHotrack is true in options, still no hottrack when running the project  :-\

When asking these kinds of questions, it's always useful to
- mention Laz+FPC+OS version (ok, win+Laz 1.0.12+FPC 2.6.2)
- include a sample project as a zip if possible (project/publish project, zip up, attach to post)
See first link in signature.
thanks.

You might want to try my TTreeListView.

It should support hottracking (although I have never used it)

Don't forget that it is released under GPL, which means that we cannot use it unless our software is also under GPL.

GPL should be treated as religion be proud that you support it but do not try to shove it down my throat.

Could you stop making these wild claims? I agree with what taazz said.

Then do not use RTL, do not use FCL, do not use LCL, they are evil.
