wxWidgets实现图片和文件按钮

2023-08-28 18:59:04 50

在wxWidgets中，想要通过其本身的控件来实现图片+文件的按钮，貌似不太容易做到。但是可以通过重载wxControl来自绘图片+文件按钮。下面给出的是已经封装好的按钮类：

wxBitmapButtonEx.h

BitmapButtonLeave,
BitmapButtonDClick,
BitmapButtonDisable
};

virtualboolDisable();

//设置正常图片
wxBitmapButtonEx*set_normal_bitmap(wxBitmap*bitmap);

//设置按钮按下时的切换图片
wxBitmapButtonEx*set_down_bitmap(wxBitmap*bitmap);

//设置按钮按经过时的切换图片
wxBitmapButtonEx*set_enter_bitmap(wxBitmap*bitmap);

//设置Disable图片.
