As I want to set an element as focused when a jQuery dialog is open.
I wrote kind of this code:
$(".selector").dialog({
title: "dialog",
buttons: [
{ text: "Yes", click: function () { } },
{ text: "No", autofocus: true }
]
});
This is a jsFiddle example for this case.
This seems work as I want in IE9+/Firefox/etc, but not in IE8.
So I found the _focusTabbable function in jquery-ui.
var hasFocus = this.element.find("[autofocus]");
if ( !hasFocus.length ) {
hasFocus = this.element.find(":tabbable");
}
if (!hasFocus.length) {
hasFocus = this.uiDialogButtonPane.find(":tabbable");
}
This will only find the autofocus element in the ui-content, not in the button panel.
How come there would be a call to find :tabbable in uiDialogButtonPane, but not applied [autofocus]?
More interesting, even in IE11/Firefox I saw that the function focused the "Yes" button in the end, but happened to popup a dialog with focus at "No" button. Cannot find a reason.

Problem is probably simple but I can't find the proper answer.
I have a panel with only four buttons. Just vbox with buttons. And now I want to select and press this buttons not only with mouse click but also via keyboard. So I used Ext.KeyMap and I catch every key I want to: ENTER, TAB, DOWN and UP. But I can't find simple way to move focus betveen this buttons.
E.g. I'm focused on first button, press DOWN key and I want to be focused on the second button. No way. I tried
but1.down('button[action=next]').focus(false, 100))
but it can't work. Be so kind as to prompt please.
Well what can I say, just VERY BIG thank you – it is working obviously.
I had no idea to use KeyNav.
But it’s working in such a simple example My case is a little bit more complicated and I asked this question just simplified my situation. So this menu is the second screen in my application and it is constructed in such a way:
PANEL
Panel1
Label1
Button 1
Button 2
Button 3
Panel2
Label2
Button 4
Button 5
Panel3
Label3
Button 6
Button 7
Button 8
and every user can see (panels are hidden on the start) and use parts of this structure (e.g. Panel1, 3 and Button 8). I decide about it one step before (login step) and I show to the user menu only for him in the container defined:
Ext.define('Gromel.view.Menu', {
extend: 'Ext.container.Container',
requires:[
'Ext.tab.Panel',
'Ext.layout.container.Border',
'Ext.form.Label',
'Ext.form.Panel'
],
xtype: 'app-menu',
fullscreen: true,
layout: 'fit',
...
I place your code on the PANEL level and it's working almost properly. And I use the following default definition for above items:
defaults: {
margin: '0 0 10 0',
baseCls: 'x-btn-default-large',
cls: 'cap-btn',
style: 'font-size:18px;text-align: center',
height: 40,
width: '50%',
// yours:
handler: function () {
this.up('panel').activeButton = this.activeIndex;
}
}
so I modified your cls change method to:
button[method]('x-focus x-btn-focus x-btn-default-large-focus')
and your procedure is working.
Problems I can't manage now are:
as you see on the same level as buttons I have labels and I don't know how to bypass them;
more important - I want to run this procedure only on menu panel not in login panel and the rest (deeper in my structure) but this is global, so if I press ENTER on login panel I see the effect on next, menu panel; I replaced ENTER effect in the following way (I want to press ENTER on every button in menu and run different presses events):
case e.ENTER: butt.fireEvent('click', butt); break;
So if it isn’t to much for you be so kind and prompt me more please.
Try to use ExtJS KeyNav.
KeyNav provides a convenient wrapper for normalized keyboard navigation. KeyNav allows you to bind navigation keys to function calls that will get called when the keys are pressed, providing an easy way to implement custom navigation schemes for any UI component.
As you said
I have a panel with only four buttons.
I have work around that, I have created an small sencha fiddle demo. It will show you how is working. I hope this will help you to solve your problem.

I have my fancybox close button diplay:none; when an iframe opens, I want the close button appears in a delay of x time. exactly like this DEMO.
Though it is solved in earlier version of fancy box in here, but in fancybox-3 It works for the first time and thereafter the close button doesn't appear until I refresh the page.
I use the following JS Code for delay:
$(document).ready(function() {
setTimeout(function() {
$(".fancybox-button--close").show();
}, 5000);
});
Any ideas? Thanks.
This is how you can access the toolbar and make it visible, if needed:
$('[data-fancybox="images"]').fancybox({
afterShow : function(instance, slide) {
setTimeout(function() {
instance.$refs.toolbar.show();
}, 3000);
}
});
Demo - https://codepen.io/anon/pen/oeWqrJ
But, if you want to toggle that small close button, here is an example:
$('[data-fancybox]').fancybox({
toolbar : false,
smallBtn : true,
afterShow : function(instance, slide) {
setTimeout(function() {
slide.$slide.find('.fancybox-close-small').show();
}, 3000);
}
});
Demo - https://codepen.io/anon/pen/oeWqRJ
Basically, you can access any element either from instance.$refs (collection of references to interface elements) or from slide.$slide (parent element of the content).
I need to show a refresh button on a specific card only, the title bar to which is defined in some parent Panel. I have tried in the following way:
Parent Panel:
config:
{
layout : 'fit',
items:[
{
xtype:'titlebar',
docked:'top',
title:'Directory',
items:[
{
xtype: 'button', //First Button-visible in all cards
docked: 'left',
iconCls: 'arrow_left',
action: 'back'
},
{
xtype: 'button', //Target button-to be visible in one card only
docked: 'right',
iconCls: 'refresh',
action: 'reset',
hidden: true //hiding this button
}
]
},
{
xtype:'tabpanel',
tabBarPosition:'top',
items:[
{
title: 'Tab1',
xtype: 'Card1'
},
{
title: 'Tab2',
xtype: 'Card2'
}
]
}
]
}
I have a hidden property set to true for refresh button in above panel, which i want to set false for a card.
The target card is set active on a button click. I am changing hidden property to false in the buttonTapListener, and then setting the target card as active. But the refresh button do not get visible. Here is the controller code:
onButtonTap: function()
{
...
var getParentPanelRef = this.getParentPanel();
var parentPanelItems = getParentPanelRef.getItems();
console.log(parentPanelItems.items[0].config.items[1].hidden); //Prints true
directoryMainContainerItems.items[0].config.items[1].hidden=false;
console.log(parentPanelItems.items[0].config.items[1].hidden); //Prints false
var directorySearchMainUIRef = this.getSomeOtherParentPanel();
directorySearchMainUIRef.setActiveItem(1); //Switches to target card
}
The value of hidden gets changed, but button doesn't come up. Please suggest an alternative if so. Thanks in advance.
Instead of hiding/showing the button you could add/destroy the button.
I had a similar problem a while a ago and it seems that sencha not always detects when it should redraw components.
Maybe your parent component'width is out of you browser and your button is docked right so that you can's see it.
I have a simple button with menu. There is a treepanel inside the menu.
Whenever user selects some node in tree, i update the container buttons text.
In treepanel's afterrender event i make a default node selection in the tree and this fire selection event and the button's text is updated.
However, when the button is rendered for the very first time, the treepanel inside the menu is not yet rendered.
How can i make menu & treepanel render silently (adding to dom but not shown to user until button is clicked) after button is rendered?
Actually there is a workaround which i hesitate to use:
btn.showMenu();
btn.hideMenu();
Any better ideas?
JsFiddle: http://jsfiddle.net/exGk3/
Code:
var selectedNodeIndex = 1;
var onItemSelect = function (selModel, node, index) {
var treePanel = selModel.view.up();
var btn = treePanel.up("button");
btn.setText(node.data.text);
};
var afterTreeRender = function (t) {
t.selModel.select(selectedNodeIndex);
}
Ext.create('Ext.Button', {
text: 'Click me',
renderTo: Ext.getBody(),
menu: {
items: {
xtype: "treepanel",
id: "tree",
indent: false,
width: 150,
height: 200,
rootVisible: false,
root: {
children: [{
text: "item 1",
leaf: true
}, {
text: "item 2",
leaf: true
}, {
text: "item 3",
leaf: true
}]
},
listeners: {
select: {
fn: onItemSelect
},
afterrender: {
fn: afterTreeRender
}
}
},
showSeparator: false
}
});
I think the easiest thing to do here is to pass along the text needed for the button. It seems that you already know which node to select in the tree, then you probably know which text corresponds to the selected index.
If that's somehow not possible or API is not changeable here is a way for you to set button text programmatically:
http://jsfiddle.net/dbrin/XSn7X/3/
The changes from what you have done are 2 fold:
Use Ext.define method to define your class with initComponent method.
The initComponet method is a hook after the constructor to setup aditional properties. The key here is that the instance of the class exists at this point and *this* context references the class instance.
Use Ext.create to create an instance of your customized button component.
In the initComponment method you just traverse the tree looking for the data you need and set the button text.
I am trying to add a tooltip on extjs overflow button, but I can't find a way to do that. It's not mentioned on docs either. Has anyone been able to do that? Either that or changing the text for the button
I found
overflowText: 'More >'
But this doesn't seem to work
You can add a tooltip to the overflow button during the afterrender event of the toolbar. The target element would be this.layout.overflowHandler.menuTrigger.el in the afterrender event.
Working jsFiddle http://jsfiddle.net/gJjTY/ (the overflow icon is in the bottom right of the toolbar, the icon isn't rendering due to lack of css)
Ext.create('Ext.toolbar.Toolbar', {
renderTo: document.body,
width : 300,
margin : '5 0 0 0',
layout : {overflowHandler: 'Menu' },
items : [
{
text : 'This is a Button',
tooltip: 'This is a tip',
},
{
text : 'This is another button',
},
{
text : "this is yet another button!"
}
],
listeners: {
afterrender: function(view){
var me = this;
console.log(me);
Ext.Function.defer(function(){
Ext.create('Ext.tip.ToolTip', {
target : me.layout.overflowHandler.menuTrigger.el,
anchor : 'left',
dismissDelay : 0,
showDelay : 0,
autoHide : true,
html : "This is a tooltip!"
});
}, 100);
}
}
});
Ext.onReady(function(){
Ext.QuickTips.interceptTitles = true;
Ext.QuickTips.init();
});
