gui FreeBasic中的彩色文本

Question

我已经制作了一个GUI，但想要更改此行的文本颜色。我试着搜索，但我所能找到的就是改变打印输出的颜色。

warn1 = CreateWindowEx( 0, "STATIC", "", WS_VISIBLE Or WS_CHILD, 20, 150, 300, 40, hWnd, 0, 0, 0 )
SetWindowText( warn1, "WARNING:")

如果可能的话，我想要红色的“警告”。

Answer 1

在父窗口中处理WM_CTLCOLORSTATIC窗口消息，并返回具有颜色画笔设置的相应设备上下文句柄。下面是一个示例：

function WinProc(hWnd As HWND, uMsg As UINT, wParam As WPARAM, lParam As LPARAM) As LRESULT
  Select Case uMsg
    Case WM_CREATE:
      warn1 = CreateWindowEx( 0, "STATIC", "", WS_VISIBLE Or WS_CHILD, 20, 150, 300, 40, hWnd, 0, 0, 0 )
      SetWindowText( warn1, "WARNING:")

    case WM_CTLCOLORSTATIC:
      If lParam = warn1 Then
        Dim As LRESULT lBrush = DefWindowProc(hWnd, uMsg, wParam, lParam)
        SetBkMode(wParam, TRANSPARENT)
        'SetBkColor(wParam, BGR(100, 100, 200))
        SetTextColor(wParam, BGR(255,0,0))
        return lBrush
      EndIf

      ...

  End Select

  Return DefWindowProc(hWnd, uMsg, wParam, lParam)
End Function
