TPageControl控件 tab卡边框怎么去掉？

[xiangshun1]

在PageControl1DrawTab里面为tab卡用背景图像填充，但是他的边框去不掉，很难看，怎么才能去掉呢？


void __fastcall TSDIAppForm::PageControl1DrawTab(TCustomTabControl *Control, int TabIndex,
const TRect &Rect, bool Active)
{

String filePath="D:\\Project\\C++Builder\\KComponent\\skin\\button_disable.bmp";
bitmap1 = new Graphics::TBitmap();
bitmap2 = new Graphics::TBitmap();

bitmap1->LoadFromFile(filePath);
bitmap2->LoadFromFile("D:\\Project\\C++Builder\\KComponent\\skin\\button_disable1.bmp");

int NewTabWidth,ImgWidth;
TRect R, SrcR, DestR;
int TabWidth;


NewTabWidth = PageControl1->Canvas->TextWidth(PageControl1->Pages[TabIndex]->Caption) + 24;

ImgWidth = 0;


ImgWidth = bitmap1->Width + 6;
NewTabWidth = NewTabWidth + ImgWidth;

if(Active)
{

SrcR = bitmap1->Canvas->ClipRect;
DestR = Rect;
DestR.Bottom = Rect.Bottom - 1;


PageControl1->Canvas->CopyRect(DestR, bitmap1->Canvas, SrcR);

}else
{
SrcR = bitmap2->Canvas->ClipRect;
DestR = Rect;
DestR.Bottom = DestR.Bottom + 2;
PageControl1->Canvas->CopyRect(DestR, bitmap2->Canvas, SrcR);

}

}

效果如下:

使用NoteBook组件试试吧

用皮肤组件更方便

截获PageControl的WM_PAINT, WM_NCPAINT等来画边框
