实现窗口在设计时的画点
实现窗口在设计时的画点

[解决办法]
要在窗口启动时就有点的话...
在FormPaint事件画就好
//---------------------------------------
void __fastcall TForm1::DrawGrid()
{
int GridSizeX = 8;
int GridSizeY = 8;
TColor GridColor = clBlack;

for (int i = 0; i <= this-> Width; i += GridSizeX) {
for (int j = 0; j <= this-> Height; j += GridSizeY) {
this-> Canvas-> Pixels[i][j] = GridColor;
}
}
}
//---------------------------------------
void __fastcall TForm1::FormPaint(TObject *Sender)
{
DrawGrid();
}
//---------------------------------------
