如何对BCGControlBarPro进行换肤
2010-07-11 20:44:25 来源:WEB开发网4、工具条图标的透明色问题;
从CBCGPToolBar派生一个子类CMyBCGPToolBar,在该子类中覆盖CBCGPToolBar的 virtual void DoPaint(CDC* pDCPaint)。这里主要处理工具条图标的透明色问题。
凡是使用CBCGPToolBar的地方全部替换成CMyBCGPToolBar。这样你的工具条就有了和皮肤一致的皮肤色。而不是Windows的系统色。代码如下:
#ifndef _MYTOOLBAR_H_
#define _MYTOOLBAR_H_
#include "stdafx.h"
class CMyBCGPToolBar : public CBCGPToolBar
{
public:
virtual void DoPaint(CDC* pDCPaint)
{

pDCPaint->GetClipBox (rectClip);
BOOL bHorz = GetCurrentAlignment () & CBRS_ORIENT_HORZ ? TRUE : FALSE;
CRect rectClient;
GetClientRect (rectClient);
CDC* pDC = pDCPaint;
BOOL m_bMemDC = FALSE;
CDC dcMem;
CBitmap bmp;
CBitmap* pOldBmp = NULL;
if (dcMem.CreateCompatibleDC (pDCPaint) &&
bmp.CreateCompatibleBitmap (pDCPaint, rectClient.Width (),
rectClient.Height ()))
{
m_bMemDC = TRUE;
pOldBmp = dcMem.SelectObject (&bmp);
pDC = &dcMem;
if ((GetStyle () & TBSTYLE_TRANSPARENT) == 0)
{
CBCGPVisualManager::GetInstance ()->OnFillBarBackground (pDC, this,
rectClient, rectClip);
}
}
OnFillBackground (pDC);
pDC->SetTextColor (globalData.clrBtnText);
pDC->SetBkMode (TRANSPARENT);
CRect rect;
GetClientRect(rect);
if (bHorz)
{
rect.bottom = rect.top + GetRowHeight ();
}
else

}

5、Skin 库的释放:
int CBCGCBDotNetExampleApp::ExitInstance()
{
ExitSkin();
