    Default ColumnTree render column based on containersize

    ColumnTree render column based on containersize


    This isnt the best code but might be helpful to someone. On render of the columntree i needed the first column to expand based on the size of the browser. It will not change on resize, but I will get back to that later. Anyway the conditional statement is long but was the quick fix I needed at the time. You might notice I use Sakis code template in this.

    Code:
    	onRender : function() {
    
    		// before parent code
    
    		// call parent
    		Ext.my.ConferenceColumnTree.superclass.onRender.apply(this, arguments);
    								
    
    		// after parent code, e.g. install event handlers on rendered components
    		this.headers = this.body.createChild({
    		cls : 'x-tree-headers'}, this.innerCt.dom);
    		// this.headers = this.getEl().createChild( //will make the header stick but takes away horizontal scroll
    		// {cls:'x-tree-headers'},this.body);
    
    		var cols = this.columns, c;
    		var totalWidth = 0;
    
    		for (var i = 0, len = cols.length; i < len; i++) {
    			c = cols[i];
    
    			// check if this column should be hidden
    			if (c.hidden === true)
    				continue;
    			var containerSize = this.ownerCt.ownerCt.getSize();
    			if((containerSize.width >= 901) && (containerSize.width <= 1000)){
    				cols[0].width = 470;
    			}else if((containerSize.width >= 1001) && (containerSize.width <= 1100)){
    				cols[0].width = 530;
    			}else if((containerSize.width >= 1101) && (containerSize.width <= 1200)){
    				cols[0].width = 630;
    			}else if((containerSize.width >= 1201) && (containerSize.width <= 1300)){
    				cols[0].width = 730;
    			}else if((containerSize.width >= 1301) && (containerSize.width <= 1400)){
    				cols[0].width = 830;
    			}else if(containerSize.width >= 1401){
    				cols[0].width = 930;
    			}
    			
    			
    			totalWidth += c.width;
    			this.headers.createChild({
    						cls : 'x-tree-hd ' + (c.cls ? c.cls + '-hd' : ''),
    						cn : {
    							cls : 'x-tree-hd-text',
    							html : c.header
    						},
    						style : 'width:' + (c.width - this.borderWidth) + 'px;'
    					});
    		}
    		this.headers.createChild({
    					cls : 'x-clear'
    				});
    		// prevent floats from wrapping when clipped
    		this.headers.setWidth(totalWidth);
    		this.innerCt.setWidth(totalWidth);
    
    	}, // eo function onRender
    	// }}}
