在CodeBlocks中用wxWidgets创建不规则窗口 博客分类: wxwidgets编程 CodeBlockswxWidgets不规则窗口
我在学习CodeBlocks(10.05,中文)中用wxWidgets(wxWidgets-2.8.12)来创建不规则窗口时,发现图片不能打包到exe文件里面,这样在发布exe程序是必须要带上相应的图片,甚是不方便,经过苦思和辛苦的查阅,终于找到解决办法,现记录下这个过程作为被查,也对与我一样痛苦挣扎的小虾们一点启示吧。
一、准备工作:
1、环境的搭建,不讲了,我的配置是:CodeBlocks(10.05,中文)和wxWidgets(wxWidgets-2.8.12)
2、准备一张图片,本例中的图片为shape.png,见附件。
二、将图片转换成*.h文件:
这里就要使用wxWidgets自带的wxrc.exe(项目在wxWidgets的安装目录中的utils文件夹里面)了。不过wxrc.exe不是现成的,需要自己编译。本例中已包含编译好的wxrc.exe,具体怎么编译就不讲了。现讲讲图片的转换过程:
1、写一个shape.xml的文件,内容如下:
<?xml version="1.0"?> <resource version="2.3.0.1"> <object class="wxBitmap" name="shape">shape.png</object> </resource>
2、转换图片:
点击“开始”菜单-“运行”,输入“cmd”,将当前目录设定为wxrc.exe所在目录,并将shape.png图片拷贝到wxrc.exe所在目录内(这样是为了方便)。
在dos窗口输入wxrc -c shape.xrc -v -o shape.h并回车,即可看到shap.h的文件了。
三、开始不规则窗口项目
1、新建一wxWidgets project项目,具体设置看图。
2、设置窗口属性
3、将shap.h拷贝到TT项目目录中,在TTApp.cpp中包含shap.h头文件,并将添加如下代码:
=====文件名:TTApp.cpp=====

#include "TTApp.h"
//(*AppHeaders
#include "TTMain.h"
#include <wx/image.h>
#include "shape.h"
//*)
IMPLEMENT_APP(TTApp);
bool TTApp::OnInit()
{
//(*AppInitialize
bool wxsOK = true;
// wxInitAllImageHandlers();
wxImage::AddHandler(new wxPNGHandler); // 必须的
wxXmlResource::Get()->InitAllHandlers(); // 必须的
InitXmlResource();
if ( wxsOK )
{
TTFrame* Frame = new TTFrame(0);
Frame->Show();
SetTopWindow(Frame);
}
//*)
return wxsOK;
}
4、在TTMain.h和TTMain.cpp中添加相应的变量和函数,OnLeftDown(wxMouseEvent& event),OnLeftUp(wxMouseEvent& event),OnLeftDClick(wxMouseEvent& event),OnMouseMove(wxMouseEvent& event),OnRightUp(wxMouseEvent& event)和OnPaint(wxPaintEvent& event)函数是自动生成的,其它的需要手动添加。
