wxWidgets實現(xiàn)圖片和文件按鈕
更新時間：2019年02月20日 14:19:35 作者：hellokandy
這篇文章主要為大家詳細(xì)介紹了wxWidgets實現(xiàn)圖片和文件按鈕，具有一定的參考價值，感興趣的小伙伴們可以參考一下
在wxWidgets中，想要通過其本身的控件來實現(xiàn)圖片+文件的按鈕，貌似不太容易做到。但是可以通過重載wxControl來自繪圖片+文件按鈕。下面給出的是已經(jīng)封裝好的按鈕類：

#include "wx/wx.h"

BitmapButtonUp,
BitmapButtonLeave,
BitmapButtonDClick,
BitmapButtonDisable
};

const wxValidator& validator = wxDefaultValidator);
bool Create(wxWindow* parent, wxWindowID id,
const wxPoint& pos = wxDefaultPosition,
const wxSize& size = wxDefaultSize,

virtual void OnDClick(wxMouseEvent& event);
virtual void OnUp(wxMouseEvent& event);
virtual bool Enable(bool enable = true);
virtual bool Disable();
//設(shè)置正常圖片
wxBitmapButtonEx* set_normal_bitmap(wxBitmap* bitmap);
//設(shè)置按鈕按下時的切換圖片
wxBitmapButtonEx* set_down_bitmap(wxBitmap* bitmap);
//設(shè)置按鈕按經(jīng)過時的切換圖片
wxBitmapButtonEx* set_enter_bitmap(wxBitmap* bitmap);
//設(shè)置Disable圖片.
wxBitmapButtonEx* set_disable_bitmap(wxBitmap* bitmap);
//設(shè)置背景圖片
wxBitmapButtonEx* set_background(const wxBitmap& bitmap);
//設(shè)置背景顏色
bool set_background_colour(const wxColour& colour);
//設(shè)置按鈕文字
