setIcon method

void setIcon(String iconPath, { bool small = true, bool big = true, bool cached = true, bool force = false, })

Sets this Window icon from iconPath.

• If small is true, sets a 16x16 icon.
• If big is true, sets a 48x48 or 32x32 icon.
• If cached is true will load the icons using loadIconCached, otherwise will call loadIcon.
• If force is true will always call sendMessage, even if the icon was already set to the same icon handler.

Implementation

void setIcon(String iconPath,
    {bool small = true,
    bool big = true,
    bool cached = true,
    bool force = false}) {
  var loader = cached ? Window.loadIconCached : Window.loadIcon;

  if (small) {
    var hIcon = loader(iconPath, 16, 16);
    if (hIcon == 0) {
      hIcon = loader(iconPath, 32, 32);
    }

    if (force || _iconSmall != hIcon) {
      sendMessage(WM_SETICON, ICON_SMALL2, hIcon);
      _iconSmall = hIcon;
    }
  }

  if (big) {
    var hIcon = loader(iconPath, 48, 48);
    if (hIcon == 0) {
      hIcon = loader(iconPath, 32, 32);
    }

    if (force || _iconBig != hIcon) {
      sendMessage(WM_SETICON, ICON_BIG, hIcon);
      _iconBig = hIcon;
    }
  }
}
