I display Panel A first, then display Panel B below it. Panel A uses JSONP to get the data and is shown in the callback function of the store load. So it takes about 1 sec to show.
I aligned a floating panel C to Panel B. The floating panel C is something like this:
Ext.define('MyApp.view.MyWindow', {
extend: 'Ext.window.Window',
height: 334,
width: 540,
layout: {
type: 'border'
},
title: 'Run report',
initComponent: function () {
var me = this;
floatingpanel = Ext.create('Ext.panel.Panel', {
html: "something",
width: 100,
height: 50,
floating: true,
listeners: {
'show': {
fn: function () {
floatingpanel.alignTo(PanelB, "tr-tr", [left, top]);
},
scope: floatingpanel,
//delay: 1000, // to wait for other component to show
single: true
}
}
});
Ext.applyIf(me, {
items: [{
xtype: 'form',
bodyPadding: 10,
region: 'center'
}]
});
me.callParent(arguments);
}
});
Then floatingpanel.show()
is called to display the panel. It is not added to Panel B though.
If I don't use delay
as shown above, the floating panel C appeared somewhere in Panel A since Panel A is not available yet when the floating panel is about to show. So I put the "delay".
After 1 sec, Panel A is shown as the callback succeeded. Now the floating panel C aligns to Panel B in the right place.
Since the callback function may succeed in 1 sec or 10 sec, the delay time is hard to choose.
Are there other ways to work this out? I tried to use doConstrain to attach the floating panel C to Panel B: floatingpanel.doConstrain(PanelB)
. But somehow it didn't work.
initComponent: function () {
var me = this;
floatingpanel = Ext.create('Ext.panel.Panel', {
html: "something",
width: 100,
height: 50,
// floating: true,
listeners: {
'show': {
fn: function () {
me.alignTo(PanelB, "tr-tr", [left, top]);
},
scope: floatingpanel,
//delay: 1000, // to wait for other component to show
single: true
}
}
});
Ext.applyIf(me, {
items: [{
xtype: 'form',
bodyPadding: 10,
region: 'center'
}]
});
me.callParent(arguments);
}
