I found the key!!
I follow the step from clicking the button to get the alert popup...these
are the steps:
* I click the button ( mousedownevent fired )
* _applyChecked fired.
* _applyChecked calls _handleItemChecked on the RadioManager.
* Radio Manager calls _applySelected. changeSelected event fired.
* changeChecked event fired on the button.
I try to modify the applySelected method...but to stop the propagation I
have to modify the first step!!!
I devleop a MyButton class extendin AbstractButton. I paste the content form
Button class.
qx.Class.define("custom.MiButton",
{
extend : qx.ui.pageview.AbstractButton,
construct : function(vText, vIcon, vIconWidth, vIconHeight,
vFlash,funcion)
{
this.base(arguments, vText, vIcon, vIconWidth, vIconHeight, vFlash);
condicion = funcion; //la funcion que se evalua para aceptar el checked
this.initChecked();
this.initTabIndex();
this.addEventListener("mouseover", this._onmouseover);
this.addEventListener("mouseout", this._onmouseout);
this.addEventListener("mousedown", this._onmousedown);
this.addEventListener("keydown", this._onkeydown);
this.addEventListener("keypress", this._onkeypress);
},
members:
{
condicion: "" // to be initialized in the constructor
},
Adds a condition member. A string to be evaluated.
_onmousedown : function(e) {
var res = eval(condicion);
if( res){
this.setChecked(true);
}
}
On mousedown I eval the condition...if I select 'No' nothings occurs. I stop
the propagation at the begin!!!
Cheers.
