【C++ 隨手小記】MFC 重構元件
1. 在Create() 時的Style要加上 BS_OWNERDRAW
2. 在Class中加上 virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
3. 在cpp 檔中繪製元件 <--- 從網路上找的
void CTvButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC dc;
dc.Attach(lpDrawItemStruct->hDC); //Get device context object
CRect rt;
rt = lpDrawItemStruct->rcItem; //Get button rect
2. 在Class中加上 virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);
3. 在cpp 檔中繪製元件 <--- 從網路上找的
void CTvButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{

CRect rt;
rt = lpDrawItemStruct->rcItem; //Get button rect

Picture control 中顯示 bitmap 的用法 (寫給我自已看的...)
1. 拉Picture 元件 並且更改 ID (因預設是用 CStatic，所以要改為別的名字)
