CXTPTreeCtrl - HasLines = doesn't

v. 16.1

Latest CXTPTreeCtrl doesn't seem to accept styles.

Try adding TVS_HASLINES|TVS_LINESATROOT and nothing happens. Worked in v. 15.3.1.

Am I missing something?

I have version 16.2.0 but this problem is not corrected. When will be fixed?

I can confirm this.
In 15.3.1:

No code changed, in 16.2.0:

... and as you can see, the space for the icons in 16.2.0 is too small, too.
Please fix and test both bugs. Thanx!

Lines (and icons) are STILL not working in version 16.2.3

Try it:

DWORD dwStyle =  WS_VISIBLE|TVS_HASLINES|TVS_LINESATROOT|TVS_TRACKSELECT|TVS_HASBUTTONS|TVS_SHOWSELALWAYS|TVS_FULLROWSELECT;

if (m_treeCtrl.Create(dwStyle, CRect(0,0,0,0), this, IDC_TREE))
{
        GetTreeCtrl().SetItemHeight(26);
}

In the treectrl demo where lines are set by dialog resource it appears OK. Create fails.

I have a perhaps related issue with a CXTPTreeCtrl using TVS_CHECKBOXES and no images. In 15.3.1 it worked fine, but in 16.2.3 I can only get TVS_CHECKBOXES to work if I also add images to all nodes, but that is not what I want.

This is still clobbered in 16.2.6

Replacing XTPTreeBase.cpp with version 15.3.1 still corrects the problems.

Is there an official fix on the horizon?

Do the CJ folks need 15.3.1 XTPTreeBase.cpp to compare? I could upload to you if you've lost it from SourceSafe or whatever source control you use.

If it were me, I would start all over from 15.3.1 and add new material from that as a clean starting point taking care that none of the functionality gets trashed. It would be a lot easier than trying to kludge together a fix to the existing broken code.

Even rolling it back would be preferable to the unusable state it's in now.

CJ please fix!

*Trying to make the current "theme" work for tree controls is a noble effort. While it is getting closer you can see it is still unusable.

15.3.1 Library captures.

Example 1 - Spacing of item icons and text is correct.



Example 2 - Position of expand/collapse buttons and line at root are correct.



16.3 Library captures.

Example 1 - Note that the item icon widths are not handled correctly. The text overwrites.



Example 2 - Note that the check boxes disregard the presence of the expand/collapse icons.



Code snippet to create Example 1:

void CMyTree::SetExplorerStyle()
{
    if (XTPSystemVersion()->IsWinVistaOrGreater())
    {
        if (!GetTreeCtrl().GetSafeHwnd())
            return;

        SetWindowTheme(GetTreeCtrl().GetSafeHwnd(), L"explorer", NULL);

        GetTreeCtrl().ModifyStyle(TVS_HASLINES, 0);

        DWORD dwExStyle = 0x0004; // TVS_EX_DOUBLEBUFFER;
           
        ::SendMessage(GetTreeCtrl().GetSafeHwnd(), TVM_SETEXTENDEDSTYLE, (WPARAM)dwExStyle, (LPARAM)dwExStyle);
    }
}
int CMyTree::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    int result = -1;

DWORD dwStyle =  WS_VISIBLE|TVS_HASLINES|TVS_LINESATROOT|TVS_TRACKSELECT|TVS_HASBUTTONS|TVS_SHOWSELALWAYS|TVS_FULLROWSELECT; // TVS_SINGLEEXPAND| // single key expand

    if (m_treeCtrl.Create(dwStyle, CRect(0,0,0,0), this, IDC_TREE))
    {
        SetExplorerStyle();

        GetTreeCtrl().SetItemHeight(26);
        m_filter = -1;
        m_subfilter = -1;
        result = 0;
    }
.... etc.

Tree control properties for example 2.

Where I was also updated to 16.4.0, I encountered this problem that check box is not displayed.

Although check box reblogged modify and recompile to be displayed correctly in immediately change the control of the theme, I would like to fundamental solution.

v. 17.1 - still problems with tree control.

The placement of lines/icons/objects etc. is improved, but there is little control over skinning.

For instance, if you don't want to use skinned expand/collapse buttons (in my case I'd like to use "explorer" type deltas regardless of skin for consistent appearance, there is no way to do so.

Changing the skin always changes the control skinning regardless of programmed setting.

Is there another way around this or an update planned soon that allows this capability (skin or not skin, skin everything except buttons)?

In addition to bad line placement as noted in previous posts, triangle selection buttons are still unresolved.

Static or DLL doesn't seem to matter.

CJ Vers: 15.3.1 vs 17.2.0
Sample: GUI_Explorer
OS: Vista+. For my test I used Win 7.

Compare:

1. Build using v15.3.1 XTPTreeBase.cpp/h from I think.. 2012!!!  You will see normal tree control triangles.

2. Build using v17.2.0 XTPTreeBase.cpp/h. Tree control triangles are not shown. [+] buttons are.

Anything using TreeBase fails.

This is unusable and has been for years.

In the VisualStudio IDE Sample I get wrong spaces between expand/collapse icons when removing the TVS_LINESATROOT flag.

Sounds great, remember to  add option to enable/disable DPI scaling of icons, so we don't get the bad situation like with button icons which are awfully scaled, and we can't turn it off.

Hello Martin,

You use state icons only for leaf items and for node items not. It's right? In this way you have this problem?

Could you please share you sample or modify our sample as for reproduce this bug?
I need to debug it.

Hello Martin,

I think, I have question from another user, look please this post
http://forum.codejock.com/forum_posts.asp?TID=23295&PID=75768&#75768
if this bug really same then this has been already fixed in version 18.0
