Re: [Php-qt-users] QGridLayout

[Ferenc V. <li...@ne...>]

Hi All,

I still don't get it. I tried to change tutorial 6 to add a different
widgets to the grid, please see the following modifications of
"LCDRange" original example class:


/* LCD and slider */

	class Test1 extends QWidget
	{
		public $lcd;
		public $slider;
		public $layout;
		
		function __construct()
    	{
    		parent::__construct();
			$this->lcd = new QLCDNumber(2,$this);
			$this->slider = new QSlider($this);

			$this->layout = new QVBoxLayout($this);
			$this->layout->addWidget($this->lcd);
			$this->layout->addWidget($this->slider);
			$this->setLayout($this->layout);
		}
	}


/* LCD only */
	
	class Test2 extends QWidget
	{
		public $lcd;
		public $layout;
		
		function __construct()
    	{
    		parent::__construct();
			$this->lcd = new QLCDNumber(2,$this);

			$this->layout = new QVBoxLayout($this);
			$this->layout->addWidget($this->lcd);
			$this->setLayout($this->layout);
		}
	}


/* Slider only */
	
	class Test3 extends QWidget
	{
		public $slider;
		public $layout;
		
		function __construct()
    	{
    		parent::__construct();
			$this->slider = new QSlider($this);

			$this->layout = new QVBoxLayout($this);
			$this->layout->addWidget($this->slider);
			$this->setLayout($this->layout);
		}
	}

Test 1 OK: contains both slider and LCD and can be added to the grid.
Test 2 CORE: contains the LCD only, adding it to the grid drops core.
Test 3 OK: contains the slider only, can be added to the grid.

$this->grid->addWidget(new Test3(), $row, $column, 0);

Anyway, will it be possible to add single widgets, like in the example
below? (Which will have no additional layout, just the widget itself.)

To test QGridLayout I tried to change my little test program to use it,
by adding Button or QLineEdit. Seems it works only with the Tutorial 6
class at the moment. ;-)

Many thanks,
Ferenc
