wxBitmapButton question

Post by roarek82 »

Hi.
I want to change shape of wxBitmapButton. I want to create own custom button.
I want create wxBitmapButton with all functions like wxBitmapButton but I dont want rectangle wxBitmapButton.
I want to draw button shape. I want to draw elipse or circle button.
ANd my question how to do it?

I know that I must inherit from wxBitmapButton class but how to change shape of this button?

Sorry for my bad english BTW

I found on internet sth like this:

Code: Select all

class PlayButton : public wxBitmapButton
{
public:
    PlayButton(wxWindow* parent, wxWindowID id, int size);
};

const float MFACTOR = 0.22;

PlayButton::PlayButton(wxWindow* parent, wxWindowID id, int size)
{
    // calculate the triangle points
    int low  = (int) int((size - 4) *    MFACTOR)  + 2;
    int high = (int) int((size - 4) * (1-MFACTOR)) + 2;
    wxPoint points[3] = { wxPoint(low,  high), 
			  wxPoint(high, size/2), 
			  wxPoint(low,  low) };

    wxBitmap bitmap(size, size);
    wxMemoryDC dc;

    // draw the triangle
    dc.SelectObject(bitmap);
    dc.Clear();
    dc.SetPen(*wxBLACK_PEN);
    dc.SetBrush(*wxBLACK_BRUSH);
    dc.DrawPolygon(3, points);
    dc.SelectObject(wxNullBitmap);

    Reparent(parent);
    SetBitmapLabel(bitmap);
}
but it doesnt working

there is link http://lists.wxwidgets.org/archive/wx-u ... 27197.html


Regards
Kamil

BTW How to simply make own controls? I meaning change shape , colours and other functions.

Did you try to move the drawing part of the code into the "Draw" function instead of letting it in the constructor?
