Event for wxListCtrl scrolling Topic is solved

[extreme001]

Hi!

I'm searching for a ScrollEvent on wxListCtrl. Is there anyway to find out if the scrollbars of wxListCtrl was used? Scroll-UP, Scroll-DOWN, LEFT and RIGHT scroll? Please help and thank you very very much!

Would Event table macros from wxScrollBar be of any help?

[extreme001]

No...i tried it...doesn't work!

Ok, then see if these are the ones:

Code: Select all

wxScrollWinEvent

EVT_SCROLLWIN(func)                Process all scroll events.
EVT_SCROLLWIN_TOP(func)            Process wxEVT_SCROLLWIN_TOP scroll-to-top events.
EVT_SCROLLWIN_BOTTOM(func)         Process wxEVT_SCROLLWIN_TOP scroll-to-bottom events.
EVT_SCROLLWIN_LINEUP(func)         Process wxEVT_SCROLLWIN_LINEUP line up events.
EVT_SCROLLWIN_LINEDOWN(func)       Process wxEVT_SCROLLWIN_LINEDOWN line down events.
EVT_SCROLLWIN_PAGEUP(func)         Process wxEVT_SCROLLWIN_PAGEUP page up events.
EVT_SCROLLWIN_PAGEDOWN(func)       Process wxEVT_SCROLLWIN_PAGEDOWN page down events.
EVT_SCROLLWIN_THUMBTRACK(func)     Process wxEVT_SCROLLWIN_THUMBTRACK thumbtrack events (frequent events sent as the user drags the thumbtrack).
EVT_SCROLLWIN_THUMBRELEASE(func)   Process wxEVT_SCROLLWIN_THUMBRELEASE thumb release events.

Well....it seems to be impossible. Thank you very much for your help.

Is something changed since 2009? Who knows how to catch scrolling event in wxListCtrl?

[catalin]

Looks like nothing has changed in wxW 3.0.0. Such events are not emitted, but I guess a patch adding them (wxEVT_SCROLL_* or wxEVT_SCROLLWIN_* type of wxScrollEvent or wxScrollWinEvent respectively ?) would be welcome.

The candidate locations seem wxListMainWindow::ScrollList() in src/generic/listctrl.cpp
and wxListCtrl::ScrollList() in src/msw/listctrl.cpp .
Of course it's better to discuss this first on the wx-users or wx-dev mailing lists.

Hi!

I've seen this topic coming up again. Sadly but true: I think it's a bit to complicated to develop applications with wx. The community is nice but not the same as Qt as an example. The "movement" and "growness" in wx is not as i expected...

Thank you anyway for your help!

Qt has at least 100 times (not exaggerated) more man power than wx.

And regarding the initial question: wxListCtrl is a native control under Windows and does not derive from wxScrolledWindow. So it will never emit those events. If you really need this, you could try using wxGenericListCtrl instead.
