Summary0024692: TTreeView does not reduce space to text if no icon image is selected.
DescriptionIf TTreeView has ImageLists assigned to property "Images" and/or "StateImages" but no images is selected for display (ImageIndex, SelectedIndex, StateIndex set to "-1") the space to the text isn't reduced. Instead an empty space remains.
Steps To Reproduce- Add a TreeView and two ImageLists to the form
- Set TreeView.Images and TreeView.StateImages to the ImageLists
- Load some images/icons into the ImageLists
- Add an Item to the TreeView (double click on the TreeView on the form)
- Click "New Item"

--> A large empty space to the text is present when no image is selected (eg. ImageIndex/SelectedIndex/StateIndex = -1)
Additional InformationCan easily be resolved by enclosing two subsequent lines in a begin-end block in of the lcl. See code marked green in the attached image.
TagsNo tags attached.

In revision 42478 this is still not fixed, despite being marked as "fixed in revision 41956".

You can see the difference for example in the IDE "Messages" window.

Please provide a complete example.

I just did a fresh install of the current revision 42478 to a Windows 7 x64 system.
I opened "\lazarus\lcl\include\" with lazarus and scrolled to line no. 4878.
There's no change to the code, as I suggested in the attached image of my original bug report. It's still the old code.
I also reopened one of my projects, rebuilt and recompiled it and theres also no change. It still displays the gap. So both the source code and the precompiled units were not fixed.

The new feature is in 1.1 and above, not in 1.0.x.

Maybe we are talking about different things. I uploaded a screenshot of the IDE messages window. You can see the difference between with and without icon.

OK, I just tried the 1.1.99pre-release revision 42829 and I can confirm the changes there. Are there no bugfixes applied to 1.0.x versions?

This is confusing, because I was referring to "Product Version 1.0.10" in the bug report and the issue history only says "Fixed in revision 41956" but not which version. I assumed the 1.0.x branch since its version and revision number was also updated over time.

It breaks custom draw code and therefore will not be applied to 1.0.x.

I set the Fixed version.
