Can I subclass the window procedure of Lister?

[nyam]

Dear Ghisler,

Always thanks for your work.

I want to subclass the Lister's window procedure to remove flickering background of lister plugin.

So I subclassed the Lister's window procedure in ListLoad.
And the subclassed window procedure processes the WM_ERASEBKGND with only 'return TRUE;'.
(It seems to use WM_ERASEBKGND message rather than hbrBackground member of WNDCLASS.)

But The window procedure seems to be changed after ListLoad returns.
(The after window procedure seems to process the WM_ERASEBKGND with the Lister color.)
(I noticed the address of window procedure is 0x4???????. not a subclassed DLL image base address. (0x1???????) )

How can I subclass the Lister's window procedure?
Or is there any other solution?
(To do nothing when painting background. (WM_ERASEBKGND) )

Exactly. Actually Lister subclass your window created on ListLoad.

Thanks, but I already know that.

I told about the main 'Lister window'.

Ah, I see.
Just don't forget about Ctrl+Q. This case may require some special processing because lister window is child of TC panel.

You should be very careful with that, because other programs also start to use Total Commander plugins, even from myself (standalone lister).
