Set border width/height

[sebastien247]

Hi,

First, sorry for my english. I have one question. How can I set border size ?
I tried changed WM_NCCALCSIZE without succes.

Thanks

Not author here, but I think I can answer your question here.

In MainWindow.cpp, there are two places that dictate border size. Within the WndProc function, the border width is defined in the WM_NCHITTEST case. Then later in the WM_SIZE case that number is used to resize the mainPanel accordingly. X and Y is purely the borderWidth (defined in WM_NCHITTEST) times two. And the width and height is the border size times two. If the app is maximized, then the height and width is border size times four.

For our app, I broke the borderWidth out to a class variable and then updated the case logic to use the class variable rather than use hard coded values.

 case WM_NCHITTEST: {
      if ( window->borderless )
      {
        if ( window->borderlessResizeable )
        {
          const LONG borderWidth = 8; //in pixels

...

    case WM_SIZE: {
      RECT winrect;
      GetClientRect( hWnd, &winrect );

      WINDOWPLACEMENT wp;
      wp.length = sizeof( WINDOWPLACEMENT );
      GetWindowPlacement( hWnd, &wp );
      if ( wp.showCmd == SW_MAXIMIZE ) {
        QPushButton* pushButtonMaximize = mainPanel->findChild<QPushButton*>( "pushButtonMaximize" );
        pushButtonMaximize->setStyleSheet( "#pushButtonMaximize {image: url(:/SystemMenu/Icons/Restore.png);} #pushButtonMaximize:hover { image: url(:/SystemMenu/Icons/RestoreHover.png); }" );
         //RESIZE PANEL BASED ON borderWidth
        mainPanel->setGeometry( 16, 16, winrect.right - 32, winrect.bottom - 32 ); 
      } else {
        QPushButton* pushButtonMaximize = mainPanel->findChild<QPushButton*>( "pushButtonMaximize" );
        pushButtonMaximize->setStyleSheet( "#pushButtonMaximize {image: url(:/SystemMenu/Icons/Maximize.png);} #pushButtonMaximize:hover { image: url(:/SystemMenu/Icons/MaximizeHover.png); }" );
        //RESIZE PANEL BASED ON borderWidth
        mainPanel->setGeometry( 8, 8, winrect.right - 16, winrect.bottom - 16 );
      }
      return DefWindowProc(hWnd, message, wParam, lParam);
    }
