Do you pass the app window as parent for wxBusyInfo? It should center on that window. If it doesn't it could be considered a bug and it might be worth opening a ticket at http://trac.wxwidgets.org

Hi,
OK, but what purpose has the SetWindowStyleFlag function if it has more or less no effect?

It works for some (maybe even many) flags, but not for all.

Thanx, this somehow works, but the focus jumps out of the grid when pressing tab in the choiceEditor. That was just a test. The next step would be to find out what exactly make the choice editor disappear. Do you think this is something to post as a wxwidgets bug? I mean the necessity to use CallAf...

Yes, this is possible. The easiest way is to save the file to a temporary path and just create a normal <img> tag with the absolute path. A more elegant, but also more complicated way would be to use wxMemoryFS in order to display the file from memory. The documentation for wxMemoryFS shows some sam...

Unfortunately i didn't have enough time tonight to dig deep into it. But i traced through the code and the wxChoice editor definitely gets created and shown, but it closes again very quickly. I think even with CallAfter, the call to EnableCellEditControl() comes too early in this case. The next step...

In cases like this the first thing to do is to browse through the public methods of the classes in question. E.g. wxNoteBook only has a few methods and you quickly would have discovered: wxNotebook::GetPageText https://docs.wxwidgets.org/trunk/classwx_notebook.html#ac918c84c13ed08e7a185a5edc1116910 ...

Can you strip together a running sample?

These two methods should help:

These two are the key conditions: - DLL must have its own set of wxWidgets libraries (or not use wxWidgets at all). This means that you must not have the case where both the host app and the DLL link dynamically to wxWidgets. All other combinations should work. I assume that this happens when you bu...

These flags are usually converted to the corresponding flags for the underlying native control only when it is created. But changing these flags afterwards is sometimes not supported.

You'll probably have to recreate the control if you want to change that style.

I don't think that's possible with the native control. But if you don't want scrollbars, you probably only have a fixed, small number of items to display. Does wxGrid work for your purpose? It's a generic control, so you have more control over it,

I found wxDataViewCtrl just inherited from wxDataViewCtrlBase under Mac OSX, but under Windows, it is inherited from wxDataViewCtrlBase and wxScrollHelper, I am wondering, is it possible to make wxDataViewCtrl inherited from wxDataViewCtrlBase and wxScrollHelper under Mac OSX, same as Windows? No. ...

There is no event that happens when you change a variable somewhere. And modifying a variable of another class - or even a global variable - directly, is not a good idea. In the class where the variable is defined, you should add a method to set that variable. And in that method you should also chan...

While the wxEntry will work for windows there is no functional equivalent for osx/linux No, the wxEntry part and everything else does exists and is identical for all platforms. I just meant that the "dll" sample uses Windows specific code and there is no Linux or OSX version. So you'll have to expe...
