Rounded rectangular button

How to make the rectangular button look like rounded rectangular?

You should try to make your own Buttonclass,
an do the drawing there. wxWindow offers no SetShape
like wxTopLevelWindow does.

How rounded...?
My wxButton's are rounded rectangles, for example - as I use a theme that draws buttons as slighly rounded rectangles (for the outline).

In fact you have to assign a wxBitmap to your custom wxBitmapButton with transparent borders.

Problem. To get a transparent wxBitmap I would do the following.

1)Get some tool to convert your *.png ( I prefer to work with png) to a *.cpp. I use the "bin2c.c". But ImageMagick could also do it. Convert!

2)Include the "yourImage.cpp" to your project. And generate a wxBitmap. Inside of the cpp-File you will find a array holding your picture informations. For this I use some code I found:

Code: Select all

inline wxBitmap _wxGetBitmapFromMemory(unsigned char *data, int length) {
           wxMemoryInputStream is(data, length);
           return wxBitmap(wxImage(is, wxBITMAP_TYPE_ANY, -1), -1);
           }

ahh, you have to include -wx/image.h- and -wx/mstream.h-

3)Assign your new wxBitmap to your own wxBitmapButton

That's all...

But attention!! Make sure you don't use a backgroundimage inside the window you are adding the bitmap. Because the transparent regions of your bitmap don't know that there is a bitmap. And so they will show the systembackground of the window they have been added to.

Have fun
