Please let me know, how to add checkbox column in a grid.
I tried the following. But its read only checkbox.
Should I use checkboxModel? if so, then please let me have the complete code
Here you go, an Ext4 example matching any data element:
{
xtype: 'checkcolumn',
header: 'My Checkbox column',
dataIndex: 'myBooleanFieldThatMatchesTheModelFieldOfMyGridStore',
listeners: {// In case you want to perform a specific action on click...
checkChange: me.onCheckChange
},
flex: 1
}
Here is an example of a grid with a checkbox.
var sm = Ext.create('Ext.selection.CheckboxModel');
var grid2 = Ext.create('Ext.grid.Panel', {
store: //
selModel: sm,
columns: //[]
columnLines: true,
width: 600,
height: 300,
frame: true,
title: 'Framed with Checkbox Selection',
renderTo: Ext.getBody()
});

I have panel with border layout:
var panel = new Ext.Panel({
width:'100%',
height:'100%',
layout:'border',
renderTo:'wrapper',
defaults: {
collapsible: true,
split: true,
bodyStyle: 'padding:15px'
},
items: [{
title: 'Header',
region: 'north',
height: 150,
minSize: 75,
maxSize: 250,
cmargins: '5 0 0 0',
html: Ext.get("header-div").getHTML()
}
......
and I have a tree
var tree = Ext.create('Ext.tree.Panel', {
xtype: 'tree-xml',
id:'treegrid',
title: treeTitle,
width: '80%',
height: '80%',
renderTo: Ext.get("tree"),
....
My question is:how can I refernce tree in my panel, which means I want to append the tree into
'north' region of panel.
Thanks.
How to reference components in Extjs:
var treeReference = Ext.ComponentQuery.query ('tree-xml [title=treeTitle])[0]; // basically you are saying get me the first component you find that is a tree-xml and that its title is treeTitle
Check out the docs in sencha.
Be careful to refer to element 0 of the array (query method returns an array even if there is only 1 element matching).
Use methods add and remove from panels and containers to achieve desired functionality.
Best regards.
I have created a toolbar with menu item in it:
Ext.create('Ext.toolbar.Toolbar', {
renderTo: document.body,
padding: '30 0 0 0',
width : '100%',
items: [
{
xtype: 'splitbutton',
text : 'File',
menu: Ext.create('Ext.menu.Menu', {
width: 200,
margin: '0 0 10 0',
items: [
{
text: 'Import',
// code here
}
]
})
}
]
});
So what I am trying to do is to be able to use Import button just like File->Open.
I know that I can add xtype: 'filebutton', but it shows the browse button with the text field.
Also I want to let the user to choose only certain file extensions. After file is selected (we click open), I want to add it to my file tree in my viewport.
Thanks for any help.
I figured it out by using xtype: 'fileuploadfield' and hiding the file name/text field.
xtype: 'fileuploadfield',
buttonText : 'Open',
buttonOnly: true,
It is as simple as it gets. Just create a toolbar and have this code in its item field.
How to have 2 lists in one single panel in sencha touch 2?
I can see the first list if i use
layout:'card'
I tried :
layout: {
type: 'vbox',
align: 'stretch'
}
Please let me know how can i have 2 lists inside the same panel.
You need to use the flex config on each of your list.
You can see and example below here : Sencha Fiddle
Hope it helps

try this method
Hi #Akshatha you can try this into your Ext.Panel,
...
layout: {
type: 'hbox',
align: 'stretch'
},
items: [
{
xtype: 'list',
width: '40%',
flex: 1,
styleHtmlContent: true,
...
},
{
xtype: 'list',
width: '60%',
flex: 0.5,
styleHtmlContent: true,
...
},
]
...
You can define the width of Panel and you have Ext.List.
I hope help you. :)
I had rendered a list using SENCHA.Now i want to navigate to different screen/load different screen upon clicking the item in LIST.
var templist = new Ext.List( {
title:"xmli",
itemTpl : '{ename}',
floating: true,
indexBar: true,
width: 350,
height: 370,
centered: true,
store:xmlStore,
modal: true,
onItemDisclosure: {
scope: 'test',
handler: function(record, btn, index) {
// I need to a load different page here how ?.
// ChangePage();
}
},
hideOnMaskTap: false
}).show();
Please help me how can we achieve this using SENCHA.
Thanks,
Shyam
You need to put this list inside a layout where you can switch the visible component to your different page. It sounds like you could use the card layout:

I've tried adding style: float: right to the button but it isn't working.
myapp.cards.home.add({
xtype: 'button',
id: 'previmagebutton',
// text: 'p',
iconCls: 'arrow_left',
iconMask: true,
style: 'float: right'
});
myapp.cards.home = new Ext.Panel({
scroll: 'vertical',
id: "home-card",
layout:{
type:"vbox",
align:"center"
},
items: [header]
});
myapp.mainPanel = new Ext.Panel({
fullscreen: true,
layout: "card",
cardAnimation: 'slide',
items: [myapp.cards.home]
});
I have to use the add method if that is what's causing the problem. Many thanks.
In your myapp.cards.home object you have the layout set up to align:"center".
I've succeeded in creating a floating button by using
floating:true
config on the button. It is a private member, so I'm still looking for an official way.
This should work ::
layout : {
type : 'vbox',
align : 'left'
}
or you can add a spacer if its in the toolbar, or if you stretch the element, then add another hbox element on its side with a flex that occupies as much space that you don't need
