Examples

          {
    UI::OpenDialog(
	       `VBox(
		     `PushButton("First"),
		     `PushButton("Second"),
		     `PushButton("Third")
		     )
	       );
    UI::UserInput();
    UI::CloseDialog();
}

        
          {
    UI::OpenDialog(
	       `HBox(
		     `PushButton("First" ),
		     `PushButton("Second"),
		     `PushButton("Third" )
		     )
	       );
    UI::UserInput();
    UI::CloseDialog();
}

        
          {
    // Layout example:
    //
    // Build a dialog with three equal sized buttons.
    //
    // The equal `HWeight()s will make the buttons equal sized.
    // When resized, all buttons will resize equally in order to
    // maintain the equal layout weights.
    
    UI::OpenDialog(
	       `HBox(
		     `HWeight(1, `PushButton( `opt(`default), "&OK" ) ),
		     `HWeight(1, `PushButton( "&Cancel everything" ) ),
		     `HWeight(1, `PushButton( "&Help"   ) )
		     )
	       );

    UI::UserInput();
    UI::CloseDialog();
}


          
          {
    // Layout example:
    //
    // Build a dialog with three widgets without any weights.
    //
    // Each widget will get its "nice size", i.e. the size that makes
    // the widget's contents fit into it.
    //
    // Upon resize the widgets will keep their sizes if enlarged
    // (since none of them is stretchable), i.e. there will be empty
    // space to the right.
    //

    UI::OpenDialog(
	       `HBox(
		     `PushButton( `opt(`default), "OK" ),
		     `PushButton( "Cancel everything"  ),
		     `PushButton( "Help" )
		     )
	       );

    UI::UserInput();
    UI::CloseDialog();
}


          
          {
    // Layout example:
    //
    // Build a dialog with three widgets with different weights and
    // two widgets without any weight.
    //
    // All widgets will get at least their "nice size". The weighted
    // ones may get even more to maintain their share of the overall
    // weight.
    //
    // Upon resize all widgets will resize to maintain their
    // respective weights at all times. The non-weighted widgets will
    // retain their "nice size" regardless whether or not they are
    // stretchable. 
    //

    UI::OpenDialog(
	       `HBox(
		     `HWeight( 33, `PushButton( `opt(`default), "OK\n33%" ) ),
		     `PushButton( `opt(`hstretch), "Apply\nNo Weight" ),
		     `HWeight( 33, `PushButton( "Cancel\n33%" ) ),
		     `PushButton( "Reset to defaults\nNo Weight" ),
		     `HWeight( 66, `PushButton( "Help\n66%"   ) )
		     )
	       );
