NM_DBLCLK with Tab Control

[Grincheux]

I don't received NM_DBLCLK from my Tab control;
Each time I make a double-click I received NM_CLICK

With a ListView, no problem.

Who could help me?
Thank You

[Grincheux]

There is no more problem.
Thank You

There is no more problem.

Please write a solution
someone will look for such a problem in the future.

Or was it some kind of personal mistake? Like a typo or something like that?

For the ghosts

Here is a link to the project.

The program is not finsihed it is for illusrating the post.
I saw the solution here:https://social.msdn.microsoft.com/Forums/vstudio/en-US/8830d039-afe0-457a-9ab6-d3752c0f88be/cant-get-nmdblclk-notify-from-tab-control?forum=vcgeneral
Many people have the same problem: No double-click (left or right) with a tab control.
The solution :
Subclass the TAB window proc
When the TAB detects a WM_LBUTTONDBLCLK and Send a WM_NOTIFY with NM_DBLCLK

Sorry it is in assembler

[John Z]

It is interesting, I might try a test in C.  I've never used the Tab control.  I know some controls only notify and/or also notify through WM_NOTIFY to the main message loop.  Treeview and Statusbar are two for example, but these do not need subclassing.

I wanted to add an icon on the tab.
I did not know how to do it, so I tried the double-click.

[algernon_77]

Hello,

I've also used subclassing and WM_LBUTTONDBLCLK processing in order to catch double clicks. I don't know if it's the right way, but it works and, like you, couldn't convince WM_NOTIFY to deliver

I have a few functions that I use when working with the tab control, maybe you'll find some use for them. There are a couple which deal with tab icons.

Thank You algermon_77, I like the first function that change the style.
I will study it and will use it.

[algernon_77]

The window class style mod was intended to make a tab with many pages behave less flickery on a system with very low video resources (I also uncommented the second call to SetClassLongPtr - if you disable CS_HREDRAW|CS_VREDRAW then shouldn't use gray brushes). Don't know if it's much use on a modern system, never bothered to benchmark

I modified the window style to remove hot tracking (just a matter of personal preference).

[John Z]

It is amazing to me that the Micro$oft documentation for the TAB control all indicates that NM_RDBLCLK, and NM_DBLCLK should be available but as everyone has pointed out it is not true.  I never tried using the TAB control until now.  If I every need it in a project, with dbl clicking, I'll be back to this thread.

if you disable CS_HREDRAW|CS_VREDRAW then shouldn't use gray brushes). Don't know if it's much use on a modern system, never bothered to benchmark

If you disable CS_HREDRAW and CS_VREDRAW, windows will not generate WM_ERASEBKGND
https://docs.microsoft.com/en-us/windows/win32/winmsg/wm-erasebkgnd
I accidentally removed them and was surprise while processing the WM_PAINT message.
To avoid this I do like this:

I create 3 DCs
DC1 = CompatibleDC
DC2 = Compatible DC
DC3 = GetDC or BegingPaint
In the first I draw the image with resize (StretchBlt)
I draw the background in the DC2 => I make the WM_ERASEBKGND
In the second I transfert from the DC1 to DC2 using Bitblt
In the third, The window DC I use Bitblt to transfert the final image from DC2 to DC3

And I think there are others controls...
