Positioning individual items in hbox layout extjs - extjs

Is it possible to position some of my items in my panel to the left, and the last items all the way to the right? So that there is an empty space in the middle. Right now I am using hbox layout, and put an empty container in the middle and flex it like this:
items: [{
xtype: 'container',
layout: 'hbox',
items: [{
xtype: 'label',
text: 'Filter on vehicle'
},{
xtype:'textfield'
},{
xtype: 'button',
text: '...'
},{
xtype: 'container',
flex:1
},{
xtype: 'button',
text: 'New'
},{
xtype:'button',
text: 'Edit'
},{
xtype: 'button',
text: 'Delete'
}]
}]
Any better way to do this?

Don't know if it is a better solution or not.But DOM wise it will be lighter.
We can use tbfill xtype instead of inserting a container.
{
xtype: 'container',
layout: 'border',
items: [{
xtype: 'label',
text: 'Filter on vehicle',
},{
xtype:'textfield',
},{
xtype: 'button',
text: '...',
},
{
xtype:'tbfill'
},{
xtype: 'button',
text: 'New',
},{
xtype:'button',
text: 'Edit',
},{
xtype: 'button',
text: 'Delete',
}],
}
Working Example

If you want to use elements like button, textfield, label, combobox... You can use Ext.toolbar.Toolbar xtype: toolbar. So if you need to put items to the right you can easy do this with '->', also you can use '|' to put vertical separator to the tollbar.
Ext.create('Ext.container.Container', {
renderTo: Ext.getBody(),
items: [
{
xtype: 'toolbar',
layout: 'hbox',
items: [
{
xtype: 'label',
text: 'Filter on vehicle'
},
{
xtype: 'textfield'
},
{
xtype: 'button',
text: '...'
},
{
xtype: 'button',
text: 'New'
},
'->',
{
xtype: 'button',
text: 'Edit'
},
{
xtype: 'button',
text: 'Delete'
}
]
}
]
});

What you're doing is fine, and arguably the best solution with 1 minor suggestion. Use 'component' instead of 'container' as that will be slightly lighter.
The previous answers of 'tbfill' and '->' are actually the same thing as what you're doing. '->' is a shorthand for 'tbfill' and 'tbfill' is literally a flex:1 component.
All 3 solutions should work fine but I like using a flex:1 component because using tbfill depends on knowing an implementation detail of toolbar, namely that is uses hbox. Sencha is free to change how toolbar and tfill work in a future release, at which point your code (if it uses tbfill) is broken.

Ext JS: add item to my existing toolbar dynamically

I've been playing with this for hours and cannot get it to work.
I am trying to add items to a toolbar I have in my view.
I know the proxy is working from the server because I am printing results to console successfully.
please assist... I've been looking in documentation and cant see to find result
Use method addDocked of panel instead method add of dockedItems. (example)
function addToolbar() {
this.up('panel').addDocked({
xtype: 'toolbar',
dock: 'top',
items: [{
text: 'user 1'
}, {
text: 'user 2'
}]
});
};
var filterPanel = Ext.create('Ext.panel.Panel', {
width: 300,
heigth: 300,
title: 'Example',
items: [{
xtype: 'button',
text: 'add toolbar',
handler: addToolbar
}],
dockedItems: [{
xtype: 'toolbar',
dock: 'left',
items: [{
text: 'user 1'
}, {
text: 'user 2'
}]
}],
renderTo: Ext.getBody()
});
For adding new button to existing toolbar in your example use:
view.down('toolbar').add({ text: 'user X' });
I not sure, do you want add new toolbar with buttons, or just want to add new buttons to exist toolbar? This example add new toolbars, as you try to do in your code.
Try something like:
dockedItems: [
xtype: "toolbar",
reference: "myMenu",
items: [...]
]
Then:
this.lookupReference("myMenu").add({text: "new button"});

load grid panel into content panel

I try to understand the basics of the extjs MVC.
I created the example app with the Sencha CMD. This comes with some basic things. What i try to make is a panel with a toolbar where i have a menu. When i click on a item in the menu i want to load a grid into the panel.
What function do i need to do this?
This is my mainmodel
Ext.define('JustRent.view.main.Main', {
extend: 'Ext.container.Container',
requires: [
'JustRent.view.main.MainController',
'JustRent.view.main.MainModel',
'JustRent.view.main.ProductenType'
],
xtype: 'app-main',
controller: 'main',
viewModel: {
type: 'main'
},
layout: {
type: 'border'
},
items: [{
region: 'center',
id: 'contentBlock',
xtype: 'panel',
layout: 'fit',
title: 'JustRental',
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [{
xtype: 'button',
text: 'Menu',
menu: {
xtype: 'menu',
items: [{
xtype: 'menuitem',
text: 'verhuur',
menu: {
xtype: 'menu',
items: [{
xtype: 'menuitem',
text: 'Offertes',
menu: {
xtype: 'menu',
items: [{
xtype: 'menuitem',
text: 'Overzicht'
},{
xtype: 'menuitem',
text: 'Nieuwe offerte'
},{
xtype: 'menuitem',
text: 'Openstaande offertes'
},{
xtype: 'menuitem',
text: 'Geannuleerde offertes'
}]
}
}, {
xtype: 'menuitem',
text: 'Projecten',
menu: {
xtype: 'menu',
items: [{
xtype: 'menuitem',
text: 'Overzicht'
}]
}
}, {
xtype: 'menuitem',
text: 'Producten',
menu: {
xtype: 'menu',
items: [{
xtype: 'menuitem',
text: 'Overzicht'
},{
xtype: 'menuitem',
text: 'Artikelen'
},{
xtype: 'menuitem',
text: 'Groepen'
},{
xtype: 'menuitem',
text: 'Type',
handler: 'onClickButton',
},{
xtype: 'menuitem',
text: 'Soort'
},{
xtype: 'menuitem',
text: 'Merk'
}]
}
}, {
xtype: 'menuitem',
text: 'Klanten'
}]
}
},
{
xtype: 'menuitem',
text: 'verkoop'
}
]
}
}]
}]
}
]
});
when i click on an item i use a basic handler. This is located in my mainController file:
Ext.define('JustRent.view.main.MainController', {
extend: 'Ext.app.ViewController',
requires: [
],
alias: 'controller.main',
onClickButton: function () {
console.log('click works');
}
});
this is my ProductenType
Ext.define('JustRent.view.main.ProductenType', {
extend: 'Ext.grid.Panel',
alias: 'widget.ProductenType',
requires: [
// alerts
],
xtype: 'gridpanel',
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'string',
text: 'String'
},
{
xtype: 'numbercolumn',
dataIndex: 'number',
text: 'Number'
},
{
xtype: 'datecolumn',
dataIndex: 'date',
text: 'Date'
},
{
xtype: 'booleancolumn',
dataIndex: 'bool',
text: 'Boolean'
}
]
});
but now is my question how can i load the JustRent.view.main.ProductenType into the panel with the id 'contenBlock'.
I would use a Viewport as my main container
http://docs.sencha.com/extjs/4.2.3/#!/api/Ext.container.Viewport
with a border layout http://docs.sencha.com/extjs/4.2.3/#!/api/Ext.layout.container.Border
and then use add http://docs.sencha.com/extjs/4.2.3/#!/api/Ext.container.Viewport-method-add
and remove methods http://docs.sencha.com/extjs/4.2.3/#!/api/Ext.container.Viewport-method-remove
for component manipulation within the Viewport
pro tip: avoid unnecessary over nesting of components, use the lighter Component possible in each case. e.g containers are lighter in the DOM compared to panels so if you only need a container don't use a panel (not saying this is the case) .
Also I recommend Extjs in Action, awesome book that will help you really understand the framework.

Why does the first panel of ExtJS 4.2.1 accordion layout never close?

I have an ExtJS 4.2.1 accordion layout with three panels.
When the app is first launched, the first panel is open and the 2nd/3rd are closed.
I can open and close the 2nd and 3rd, but I can never close the first panel.
Ext.define('MyAccordion', {
extend: 'Ext.container.Container',
alias: 'widget.myAccordion',
padding: 0,
margin: 0,
width: 200,
layout: {
type: 'accordion',
align: 'stretch',
animate: true,
hideCollapseTool: true
},
items: [{
xtype: 'panel',
title: 'Test Volumes',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'label',
text: 'volume one'
},{
xtype: 'label',
text: 'volume two'
},{
xtype: 'label',
text: 'volume three'
}]
}, {
xtype: 'panel',
title: 'Production Volumes',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'label',
text: 'volume one'
},{
xtype: 'label',
text: 'volume two'
},{
xtype: 'label',
text: 'volume three'
}]
}, {
xtype: 'panel',
title: 'Extra Volumes',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'label',
text: 'volume one'
},{
xtype: 'label',
text: 'volume two'
},{
xtype: 'label',
text: 'volume three'
}]
}]
});
In the following code leveraged from the 4.2.1 examples layout browser example, if the first thing you do after launching the app is click the first header, is does close, but then re-open it and it never closes again:
Ext.onReady(function() {
Ext.create('Ext.container.Viewport', {
renderTo: Ext.getBody(),
items: [{
xtype: 'panel',
title: 'Accordion Layout',
layout: 'accordion',
defaults: {bodyStyle: 'padding:15px'},
items: [{
title: 'Introduction',
tools: [{type:'gear'},{type:'refresh'}],
html: '<p>Here is some accordion content. Click on one of the other bars below for more.</p>'
},{
title: 'Basic Content',
html: '<br /><br /><p>More content. Open the third panel for a customized look and feel example.</p>',
items: {
xtype: 'button',
text: 'Show Next Panel',
handler: function(){
Ext.getCmp('acc-custom').expand(true);
}
}
},{
id: 'acc-custom',
title: 'Custom Panel Look and Feel',
cls: 'custom-accordion', // look in layout-browser.css to see the CSS rules for this class
html: '<p>Here is an example of how easy it is to completely customize the look and feel of an individual panel simply by adding a CSS class in the config.</p>'
}]
}]
});
});
Even more strange, if I do show the collapse/expand tool, the tool for the first panel stops working.
Amazing but true, but this happens because the accordion layout container does not have a height set.
Because I can't have a fixed height, this fixes the issue: flex: 1
But this seems really strange, because why should not having a height (or flex, etc) break closing the first container? Just seems weird.
An easy solution would be to add _isLayoutRoot: true to panel with accordion layout.
Ext.define('myAccordion',{
extend: 'Ext.Panel',
alias: 'widget.myAccordion',
layout: 'accordion',
_isLayoutRoot: true,
items: myItems
});
Example: http://jsfiddle.net/38mx9hs9/1/
Also it seems that this issue is fixed in 4.2.2:

Adding a toolbar to a grid - Extjs

I have the following grid here:
Ext.define('AM.view.user.List', {
extend: 'Ext.grid.Panel',
alias: 'widget.userlist',
title: 'All Users',
store: 'Users',
initComponent: function () {
this.columns = [{
header: 'Name',
dataIndex: 'name',
flex: 4
}, {
header: 'User ID',
dataIndex: 'user_id',
flex: 1
}, {
header: 'Address',
dataIndex: 'address',
flex: 3
}, {
header: 'Age',
dataIndex: 'agee',
flex: 5
}];
this.callParent(arguments);
}
});
Can a toolbar be added to the bottom of this grid or can they only be added to panels?
Also, how can I place normal text in a toolbar rather than a button?
Yes a grid panel inherits Ext.grid.Panel, you should be able to add:
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [{
xtype: 'button',
text: 'Left Button'
}, {
xtype: 'tbfill'
}, {
xtype: 'button',
text: 'Right Button'
}]
}]
Any component that has Docked layout can have toolbars docked. Since Ext.grid.Panel extends Ext.panel.Panel, you can dock to it. See the bbar config: http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.panel.Panel-cfg-bbar
You can add text items to your toolbar by adding this to the toolbar's items:
{ xtype: 'tbtext', text: 'My Text' }
Docs for this here: http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.toolbar.TextItem
Alternately you can also add button using 'bbar[...]' which is equivalent to
dockedItems: [{
xtype: 'toolbar',
dock: 'bottom',
items: [
{ xtype: 'button', text: 'Button 1' }
]
}]
this allows you to add buttons at the bottom of your gridpanel all other button properties are allowed to use.
sample code is here:
bbar: [
{ xtype: 'button', text: 'Button 1' },
{ xtype: 'button', text: 'Button 2' }
]
for more details you can refer the doc: http://docs.sencha.com/extjs/6.0/6.0.1-classic/#!/api/Ext.panel.Panel-cfg-bbar

Scrollable panel in sencha touch

i had made a panel with number of buttons in it like this,
Ext.define('BeLocal.view.Test', {
extend: 'Ext.Panel',
config: {
fullScreen: true,
height: 482,
width: 324,
scrollable: 'vertical',
items: [
{
xtype: 'button',
text: 'MyButton1'
},
{
xtype: 'button',
top: '30%',
text: 'MyButton2'
},
{
xtype: 'button',
top: '50%',
text: 'MyButton3'
},
{
xtype: 'button',
top: '96%',
text: 'MyButton4'
},
{
xtype: 'button',
top: '110%',
text: 'MyButton5'
}
]
}
});
i can show only 3 buttons now.
i want this panel scrollable so that i can show all the buttons by scrolling it down, i had set property scrollable: 'vertical' , but it doesn't work.
When i remove position of all buttons like top:50% scroll works properly, but i want all the buttons on proper position.
how can i fix this problem ?
As per the documentation:
http://docs.sencha.com/touch/2-1/#!/api/Ext.Button-cfg-top
top : Number/String
The absolute top position of this Component; must be a valid CSS length value, e.g: 300, 100px, 30%, etc. Explicitly setting this value will make this Component become 'floating', which means its layout will no longer be affected by the Container that it resides in.
Try setting style config:
items: [{
xtype: 'button',
text: 'MyButton1'
},{
xtype: 'button',
style:'margin-top: 10%;',
text: 'MyButton2'
},{
xtype: 'button',
style:'margin-top: 50%;',
text: 'MyButton3'
},{
xtype: 'button',
style:'margin-top: 96%;',
text: 'MyButton4'
},{
xtype: 'button',
style:'margin-top: 110%;',
text: 'MyButton5'
}]
Seems to works for me.
