this one helps. background-size: cover (or background-size: 100% 100%) can be used on body or another element to have the background image or color cover the whole element.

Qt QDockWidget(floating) minimizes when my MainWindow minimizes

To fix this issue A floating QDockWidget is automatically minimized when its parent QMainWindow is minimized. There is nothing you can do about that. You may have to change your QDockWidget into a QDialog (or some other QWidget) with parent = 0.

What is the Gtk event called when a window minimizes?

What is the Gtk event called when a window minimizes?

it should still fix some issue I was at the very same crossroads, wth only some info and code on python gtk, but not in C.
After looking the docs again and again I realized I got confuse by same sounding names, unions, structures and enums and bitfields. I was handling things as booleans, when it was a bitfield thingy all along.
code :
gboolean callback_func(
    GtkWidget *widget,
    GdkEventWindowState *event,
    gpointer user_data)
    //some code
    //Minimized window check
    if(event->new_window_state & GDK_WINDOW_STATE_ICONIFIED){
    //some other code
//some more other code
return TRUE;
gboolean user_function (GtkWidget *widget,GdkEvent  *event,gpointer user_data){}
gboolean user_function (
    GtkWidget *widget,
    GdkEventWindowState *event, 
    gpointer user_data){}
How to prevent minimize of child window when parent window minimizes

How to prevent minimize of child window when parent window minimizes

Hope that helps It is called "owned window", not child window. Windows ensures that the owned window is always on top of its owner. Which implies it has to be minimized when the owner is minimized.
Winforms does however support changing the owner on the fly. This sample code worked well:
code :
public partial class Form1 : Form {
    public Form1() {
    private Form ownedWindow;

    private void button1_Click(object sender, EventArgs e) {
        if (ownedWindow != null) return;
        ownedWindow = new Form2();
        ownedWindow.FormClosed += delegate { ownedWindow = null; };

    protected override void WndProc(ref Message m) {
        // Trap the minimize and restore commands
        if (m.Msg == 0x0112 && ownedWindow != null) {
            if (m.WParam.ToInt32() == 0xf020) ownedWindow.Owner = null;
            if (m.WParam.ToInt32() == 0xf120) {
                ownedWindow.Owner = this;
                ownedWindow.WindowState = FormWindowState.Normal;
        base.WndProc(ref m);

this will help The following code demonstrates an issue I'm having where closing a child window minimizes the parent window, which I dont want to happen. ,
Why is it minimizing and how can I stop it?
code :
public partial class MainWindow : Window {

  protected override void OnMouseDoubleClick(MouseButtonEventArgs e) {
    var x = new SomeDialog { Owner = this };        
    x.Closing += (sender, args) => {
      var window = sender as Window;
      if (window != null)
        window.Owner = null;
