TTreeListView

[BeniBela]

The TTreeListView is a combination of a TTreeView and TListView which paints a tree whose nodes can contain additional columns.
The component has (almost) all features of a tree view (like collapsing nodes, expanding, different tree lines) and of a list view (like columns, sorting, multiselection, owner drawing, alternating rows)
The visible item data is added as strings which will be managed by the ttreelistview, so you don't have to worry about memory allocation; and the view automatically supports sorting by columns and incremental searching by a search bar. However, you can also add custom data for owner drawing.
It has no external dependencies and should be able to run everywhere, no matter if you have linux/windows, gtk2/win32, 32/64-bit or Lazarus/Delphi.

It's nice!!. I can't wait to test it

This is exactly what I wanted for my project.
Really this is an useful component. Good Job!

Edit: On Gtk2 it's working fine, but with QT it doesn't repaint until focus changes...Are you aware?
Minor issue anyway (and maybe it is caused by some limitation of Qt widget)
I reaffirm what I said: Really good job!

Regards.

I'm installed TTreeListView and when put the component into the form in the IDE, shows and error: "Invalid Value: 100000" and i try to reducing that and shows me and simple treeview and runtime and exception is raised...

Don't forget The VirtualDBTreeEx, which permits to use data rules for checking :

Not really aware, but I kind of expected it, because qt is said to not allow to bypass  the paint event.
I will fix this bug, if I ever manage to compile the qt-LCL.

Do you have a recent Lazarus? (~0.9.30).
I honestly never place it in the design mode, but create it during runtime, since there aren't many option to set anyways.
(but one of the reasons to make this announcement was, that it was just confirmed to work fine in design mode)

[Hydexon]

Nop, i have the stable release (0.9.28.2 beta), and you mean if this is possible in runtime mode?

Wow, this is exactly what I needed in my project some times ago. I wrote my own similiar component for this. It has no TListView functionality. My component have only live search bar functionality (like in GNOME nautilus) similar to yours, but I am hiding non-matching nodes when writting. Can you add this "hiding" functionality (most important thing in my project)? I would like to use your component instead of my. Regards.

Dosen't VirtualDBTreeEx depend on VirtualTreeView? Is VirtualDBTreeEx now compatible with the latest version of VirtualTreeView because last time I tried to install VirtualDBTreeEx, it didn't work.

TTreeListView is another excellent component for Lazarus. Well done. Keep them coming....

Qt passes paint events, but my wild guess is that you are doing some paints outside of paintevent, so it won't work on carbon too.

[zeljko]

Yes, just tested your component, and that's it: you are using painting outside of paint event so it cannot work with qt and carbon (it works but it's ugly).

[BeniBela]

???
I meant that you can put (e.g.) a panel as placeholder on the form and then create the treelistview like view:=ttreelistview.create(panel); view.align:=alClient;

I will think about it.

As I said, the treelistview bypasses the paint event.
On Windows direct drawing was always faster than waiting for paint messages

Okay, I added a workaround for qt and the drawing works there.

But it removes all optimizations; does anyone know, how to disable the background erasing with the qt interface?

I'm glad to heard that. Thanks!

Probably Zeljko knows somehow...

Qt::WA_NoSystemBackground or Qt::WA_OpaquePaintEvent attributes on TTreeListView handle (viewport) should be used in that case.
