Can you use wxDropSource::GiveFeedback()?
https://docs.wxwidgets.org/trunk/classw ... f436726f7f

is it possible to allow the user to edit e.g. the second column in a wxTreeListCtrl?

No. You'll have to use wxDataViewCtrl for this. Unfortunately that takes more effort to set up and use, check the "dataview" sample that comes with wxWidgets.

As wxToolBar derives from wxWindow, it should work as a drop target (wxWindow::SetDropTarget). Then you could use wxToolBar::FindToolForPosition() to find the button where the drop happened. But i can't think of any way to start a drag from a toolbar button if a click on that button should also work...

I assume you're talking about wxStaticText? Try wxGenericStaticText instead: #include <wx/generic/stattextg.h> ... wxGenericStaticText *gstc = new wxGenericStaticText( panel, wxID_ANY, "some text", wxPoint(10,90), wxSize(200,-1) ); gstc->SetBackgroundColour( *wxRED );

@1) From an OOP point of view, i would put any persistence related code into the destructor of each individual object. This might also be interesting: https://docs.wxwidgets.org/trunk/overview_persistence.html @2) That wouldn't work. If you call Destroy(), wxWidgets itself will call delete on the po...

The default behavior of a wxFrame is to destroy itself when it's closed. And the default behavior of wxApp is to terminate the application when there are no more toplevel windows. So in most cases you don't have to do call "delete frame_p;". And if you ever wanted to do this, you should ca...

It is possible that it is fixed in master, however. Can you try with 3.0.2? I couldn't build 3.0.2 (some error in scintilla), but i tested with 3.0.4 and i couldn't create a crash there either. Tested with my code and your change to the "text" sample, both with and without removing the ev...

Does your derived class override any other methods that could interfere? I've tested the following code with a fresh wxWidgets version from GIT, under Windows and Q4OS (Was the only working Linux VM i had at hand) and it worked fine. (GTK2 build under Linux) wxPanel *panel = new wxPanel(this, wxID_A...

wxSYS_SYSTEM_FONT could be a bitmap font. Try wxSYS_DEFAULT_GUI_FONT instead. If that doesn't work, use a specific font, e.g: wxFont font(16, wxFONTFAMILY_SWISS, wxFONTSTYLE_NORMAL, wxFONTWEIGHT_NORMAL, false, wxT("Tahoma")); wxFONTSIZE_XX_LARGE is not a valid enum for this SetPointSize()....

While "colour" does bother me to some extent, the fact that there is an explicit "British" English option but no American English option is what sparked me to create this post... In that case, maybe we could rename "British English" to just "English"? (I have...

Also I think I need joinable Thread as I don´t want to use new. There are very few situations where it makes sense to create a thread object on the stack, because it would be destroyed when it goes out of scope. In 99% of cases they should be created on the heap (= with new). Apart from that: I wou...

So they are cause for the assert?

I'm not 100% sure, i haven't checked. Just try it out.

@LoganDark

Your request has been noted. However, i can't tell you when it will be fulfilled, if ever. And if the spelling of "colour" disturbs you, you may try to find help somewhere else.

Try calling AddGrowableXXX after adding the items.

Or find a way that deleting the mask does not result in black pixels?

Interesting, I had no idea that happens. I'd have to make some experiments myself. In the worst case, you'll have to keep a copy of the unmodified bitmap before applying the mask.
