What's the best way to direct menu pages?
Is it necessary to add it to handler or we can directly use xtype and how?
`Ext.define('MyApp.view.menu.Menus', {
extend: 'Ext.Panel',
requires: [
'Ext.menu.Menu'
],
items: [{
text: 'Menu item 1',
handler: 'item1'
}, {
text: 'Menu item 2',
handler: 'item2'
}
}`
Can we use xtype?
Thank you for your help!
I'm not certain that this is what you're asking. You have two options for controlling/directing the menu: either using a specific handler, as was mentioned above, or using a common listener.

I need to create a contextmenu in ExtJS 7.4 on right click but there's only childtap which only triggers on left-click event.
Is there a way to trigger that event or another for right-click?
I added two solutions. The first is a component solution (here Grid) and the second a global one.
COMPONENT
The solution would be the childcontextmenu listener.
Have a look at the following example (Modern toolkit 6+7)
const menu = new Ext.menu.Menu({
items: [{
text: 'Menu Item 1'
}, {
text: 'Menu Item 2'
}]
});
Ext.define('MyApp.MyGrid', {
extend: 'Ext.grid.Grid',
store: Ext.create('Ext.data.Store', {
fields: ['name', 'email', 'phone'],
data: [{
name: 'Lisa',
email: 'lisa#simpsons.com',
phone: '555-111-1224'
}]
}),
columns: [{
text: 'Name',
dataIndex: 'name',
width: 200
}],
listeners: {
childcontextmenu: function (grid, eObj) {
grid.deselectAll();
grid.setSelection(eObj.record);
menu.showAt(eObj.event.getX(), eObj.event.getY());
eObj.event.stopEvent()
}
}
})
GLOBAL
I can show you how to fire global events, but the problem is the target. In the following example I am using document but you can also use any view.el.on and the target will be always the view. More answers might be found here
Ext.getDoc().on(
'contextmenu',
function(e){
Ext.GlobalEvents.fireEvent('contextmenu', e);
},
Ext.GlobalEvents
);
Ext.GlobalEvents.on('contextmenu', function(eObj) {
console.log('Who dares to RightClick me?');
});
I want to remove the active tab from sencha ext.
Assume that am into controller file of the view.
Note: I have used remove() as well as destroy().
destroy() function works fine but tab header is not getting removed.
coseResultTab() {
this.getView().destroy();
}
Before Clicking on Cancel button:
After Clicking on Cancel button
You should destroy the active tab in your tabpanel, eg:
Controller
Ext.define('MyViewController', {
extend: 'Ext.app.ViewController',
alias: 'controller.myview',
destroyTab: function() {
this.getView().down('tabpanel').getActiveTab().destroy();
}
});
View
Ext.create('Ext.Panel', {
width: 400,
height: 400,
renderTo: document.body,
title: 'Panel',
id: 'myPanel',
controller: 'myview',
items: [{
xtype: 'tabpanel',
items: [{
title: 'Foo',
items: [{
xtype: 'button',
text: 'Destroy!',
handler(btn) {
Ext.getCmp('myPanel').getController().destroyTab();
}
}]
}, {
title: 'Bar',
items: [{
xtype: 'button',
text: 'Destroy!',
handler(btn) {
Ext.getCmp('myPanel').getController().destroyTab();
}
}]
}]
}]
});
Fiddle
I enhanced the answer from Matheus to meet the requirement a bit more:
not destroying the entire tab, but only the content
setting the button handler without the use of getController (please try not to use this, as it is considered bad practice by Sencha)
removed the outer panel which only added a title
Fiddle
You can also remove it using the tab bar using closeTab() which pretty much just runs a tabs.remove(tabRefOrObj);

I can add my own button to the built-in tools "Help" etc on the panel header:
tools:[
{
type:'help',
tooltip: 'Get Help',
handler: function(event, toolEl, panel){
// show help here
}
}],
header: {
layout: {
type: 'hbox',
align: 'right'
},
items: [{
xtype: 'button',
text: 'test'
}]
} ...
but button 'test' appears far left before the panel title ... header layout hbox right obviously not the way to do it :-). Button 'test' just a placeholder - I want to eventually add a menu button - so another css tool would not work - is there a simple way of doing this or do I need to use dom element positiong etc? tia.
If you're using ExtJS 4.2, you can use the titlePosition property to accomplish this. See http://jsfiddle.net/U8MSd/
tools: [{
type: 'help',
tooltip: 'Get Help',
handler: function (event, toolEl, panel) {
// show help here
}
}],
header: {
titlePosition: 0,
items: [{
xtype: 'button',
text: 'test'
}]
}
I have a grid with a toolbar as given below
{
xtype: 'tbbutton',
text: 'Button',
menu: [{
text: 'Better'
},{
text: 'Good'
},{
text: 'Best'
}]
}
I want to write handler such that when I choose 'Good' the button text should change from 'Button' to 'Good'
I am able to access text property in the handler
Please help me..
Here are two examples:
Either you can give the toolbar button an ID
....
xtype: 'tbbutton',
id: 'mytoolbarbutton',
text: 'Button',
....
and access the button using
var button = Ext.getCmp('mytoolbarbutton');
Or you can create the button like this and add it to the toolbar afterwards:
var button = new Ext.Button({
text: 'Button',
menu: [{
text: 'Better'
},{
text: 'Good'
},{
text: 'Best'
}]
});
myToolbar.add(button);
This way you have a handle to the button even though it is added to the toolbar.
For making a toolbox, I want to know how to make a radiogroup with regular buttons and not radiobuttons in latest extJS
Like this with jQueryUI: http://jqueryui.com/demos/button/#radio
Thanks in advance,

I think you should look at using a set standard ExtJS buttons. A button can be assigned to a group so that they act as the elements shown in your link.
See this example:
{
xtype: 'button',
text: 'Choice 1',
toggleGroup: 'mygroup'
}, {
xtype: 'button',
text: 'Choice 2',
toggleGroup: 'mygroup'
}, {
xtype: 'button',
text: 'Choice 3',
toggleGroup: 'mygroup'
}
Buttons also have a property called enableToggle, that allows them to toggle, and is automatically set to true when you set a toggleGroup, and toggleGroup tells ExtJS how they are related.
Note, they look like regular ExtJS buttons, but behave like you want.
There is a less complicated (better?) way to disallow deselecting a button. Set the allowDepress config option to false:
{
xtype: 'radiogroup',
layout: 'hbox',
defaultType: 'button',
defaults: {
enableToggle: true,
toggleGroup: 'mygroup',
allowDepress: false,
items: [
{ text: 'Choice 1'},
{ text: 'Choice 2'},
{ text: 'Choice 3'}
]
}
}
Just to answer #mastak's comment (in the answer above), in order to disallow the action of de-selecting a button, add this listener to each button:
listeners: {
click: function(me, event) {
// make sure a button cannot be de-selected
me.toggle(true);
}
}
That way, each click on a button will re-select it.
-DBG
Just adding to the #deebugger post. You can also use the following button property to not allow to deselect a selection
Ext.create('Ext.Button', {
renderTo : Ext.getBody(),
text : 'Click Me',
enableToggle : true,
allowDepress : false
});
