Hi everybody.
Maybe my question have a simple answer, but I don't know how to detect an Ok/Cancel button press.
I create a dialog in this way
Code: Select all
res =
"dialog { alignChildren: 'fill', text: 'xxxxx', \
...
buttons: Group { orientation: 'row', alignment: 'right', \
okBtn: Button { text:'OK', properties:{name:'ok'} }, \
cancelBtn: Button { text:'Cancel', properties:{name:'cancel'} } \
} \
}";
win = new Window (res);
win.center(); win.show();
(I omit the other fields) .. and next ?
Thanks in advance

You just need to set up a function to handle the click and then link the button to it like this:
function okClick(){
(your function here)
}
.
.
.
.
win = new Window (res);
win.buttons.okBtn.onClick = okClick;

Dan, sorry for the new question.
Obviously when I call okClick, inside the function I loose every var/obj that I create before, right ?
How can I pass that parameters ?
I tried
win.buttons.okBtn.onClick = okClick(myComp,win);
.. but I got undefined errors
Why ?

You can create variables and objects that are outside the scope of all functions and you can access those anywhere. Other than that, you can use "this" and "parent" to get at attributes of the panel objects. In your case,
"this" references the button
this.parent references the buttons group
this.parent.parent references the dialog
