extjs 3 - add progressbar and image in property grid - extjs

Is it possible to implement progressbar in property grid in extjs 3? How do I add an image in property grid?
I have a value in percentage and I want to represent that in progressbar (its uneditable).
Thanks a lot for help.

You could try something like this:
//==== Progress bar 1 ====
var pbar1 = new Ext.ProgressBar({
id:'pbar1',
width:300
});
var grid = new Ext.grid.PropertyGrid({
title: 'Properties Grid',
autoHeight: true,
width: 300,
renderTo: 'grid-ct',
bbar: pbar1, //You can set the progress bar as the property girds bottom toolbar.
customRenderers: {
Available: function(v){
return '<img src="path to image" />';
}
}, //This would render the image into the Available property.
source: {
"(name)": "My Object",
"Created": new Date(Date.parse('10/15/2006')),
"Available": false,
"Version": .01,
"Description": "A test object"
}
});
When using customRenderers to render the image
The name of the renderer type should correspond with the name of the property that it will render For more see the API.

This is the first thing I though about. But it's still not so user friendly as it's render progressbars after grid is rendered.
This is custom renderer for your progress column:
renderer: function( value, metaData, record, rowIndex, colIndex, store ) {
var id = Ext.id();
(function(){
var progress = new Ext.ProgressBar({
renderTo: id,
value: progress_value
});
}).defer(25);
return '<div id="'+ id + '"></div>';
}
It renders <div id="generated-id"/> and then renders generated progressbar into this div.
It would be better to use some kind of closure to create progressbar only once and to return it's html via custom renderer as in the example above, but unfortunately I don't know yet how to do it in Ext.js 3. As for Ext.js 4 you can see this thread at sencha forum

Extjs add chart to grid column

I had grid view in extjs, but i need to show a bar chart in each row that show a percentage of some values. How can achieve this in extjs? Maybe this image will help what i want to build.
One way to accomplish this is through deferred rendering of your chart. Basically you do this:
Create your grid column with a custom renderer.
In the renderer, you output a div with a known id. This div will ultimately contain your chart.
You defer a call (with Ext.defer) to a custom function, passing in this id (and any required info for your chart). This function will render your chart.
Inside that function, you create a chart and make it renderTo the element with your passed-in id.
This code approximates what you should do. You will probably want to refactor it more sensibly.
Ext.create('Ext.grid.Panel', {
height: 300,
store: main_data,
columns: [
{ text: 'name', dataIndex: 'name', sortable: true },
{ text: 'chart', renderer: function (value, meta, record) {
var id = Ext.id();
Ext.defer(function (id) {
var chart = Ext.create('Ext.chart.Chart', {
store: chart_data,
width: 200,
height: 100,
// other chart configuration...
renderTo: id
});
}, 50, undefined, [id]);
return "<div id='" + id + "'></div>";
} }
]
});

ExtJS extend grid RowEditor plugin (to edit array)

I've been using the ExtJS grid row editing plugin pretty liberally for CRUD operations in web applications. Now, I have a requirement to allow a database record to be edited along with a related collection/array (from another datastore) using this row editing plugin.
To do this I want to insert drag-n-drop grids inside of a row that has been selected for editing, one grid showing the available (unused) collection items on the left and another grid to hold the defined collection items on the right.
To illustrate what I am trying to do, here is the normal row editing plugin with a row selected for editing:
I am trying to do this (drag-n-drop grids inside of row editor div):
To do this I have been trying to simply run something like Ext.getCmp(???).add(myDnDGridPanel); but I haven't found the right thing to attach this to (what to put in the question marks).
It seems reasonable enough to use this plugin to edit the related collection/array along with the database record. Does anyone know a simple way to add items to this row editor div?
Or... will I have to hack/extend the plugin to accomplish this?
Below is example RowEditing plugin modification which allows to add additional components. In this demo this is only a button, but it should be easy to customize.
var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
clicksToMoveEditor: 1,
autoCancel: false,
listeners: {
beforeedit: function(editor, e, eOpts) {
var body = this.editor.body;
var container = body.down('.container-for-extra-content');
if (!container) {
container = Ext.core.DomHelper.insertAfter(body.last(), '<div class="container-for-extra-content"></div>', true);
container.setWidth(this.editor.body.getWidth(true));
container.setHeight(this.extraHeight);
this.editor.getEl().setHeight(this.editor.getEl().getHeight() + this.extraHeight);
this.editor.body.setHeight(this.editor.body.getHeight() + this.extraHeight);
var panelConfig = {
renderTo: container,
items: [this.extraComponent]
};
Ext.create('Ext.Panel', panelConfig);
}
},
delay: 1
},
extraHeight: 100,
extraComponent: {
xtype: 'panel',
items: [
{ xtype: 'button', text: 'Aloha!' }
]
}
});
Here is working sample: http://jsfiddle.net/e2DzY/1/

Why doesn't a simple click: function()... work in ExtJS?

When the user clicks on this element, I want it to show an alert.
However, when I click on the DIV that this Panel generates, nothing happens.
How can I make an alert execute when the user clicks on the following panel?
var content = new Ext.Panel({
region:'center',
margins:'5 0 5 5',
cls:'empty',
bodyStyle:'background:ivory; font-size: 13pt',
html:'<p id="test123">This is where the content goes for each selection.</p>',
click: function() {
alert('was clicked');
}
});
You haven't accepted an answer, so I'll assume you're still unclear on this. Here are a few pointers...
First, as coded your Panel will render as a plain square. If you're expecting it to look like a Panel, you should give it a title (so the title bar will render).
Second, as mentioned, click is not a Panel event (it's an Element event). So you have several ways of getting to the behavior you want. You can manually attach a listener to the underlying DOM element after the Panel is rendered:
Ext.get('txest123').on('click', function(){
alert('foo');
});
You could also do as I mentioned in the comments of another answer to generically handle any body click:
// .body is a Panel property for the body element
content.body.on('click', function(){
alert('foo');
});
If you really want to restrict the click to only the child p you could add a check:
// e is the event object, t is the target DOM node
content.body.on('click', function(e,t){
if(t.id == 'txest123'){
alert('clicked the p');
}
});
If I was coding this, I'd probably do something more like this:
var content = new Ext.Panel({
region:'center',
renderTo: document.body,
margins:'5 0 5 5',
cls:'empty',
title: 'My Panel',
id: 'txest123',
bodyStyle:'background:ivory; font-size: 13pt',
html:'This is where the content goes for each selection.',
listeners: {
'render': {
fn: function() {
this.body.on('click', this.handleClick, this);
},
scope: content,
single: true
}
},
handleClick: function(e, t){
alert(this.id); // the panel
alert(t.innerHTML); // the clicked el
}
});
Now the id is on the Panel (where it should be) and you can use Panel and/or Element methods to access child elements as needed. It's best to keep id's at the highest level possible. You'll notice too that the callback function is executed in the scope of the Panel (scope:this) so that inside handleClick you can treat this as the Panel itself and access any of its properties or methods.
So, without knowing exactly what you're trying to achieve, I can't provide you with the exact code you need. However, this should hopefully give you some ideas.
EDIT: I meant to say this originally... in your code (as posted) you are not actually rendering the Panel. As I mentioned in my answer to your related question, if you are adding the Panel as an item to a container that is lazy-rendered, the Panel's DOM won't be available for selection until after the container has rendered it. In my code above I added renderTo so that I don't have this issue, but if you're not doing that you'll have to wait until the Panel is rendered at some time later to access it.
The Panel Component does not expose a click event, so the one you're passing into the config never gets fired.
Try putting an id on your Ext.Panel object and then getting its element using Ext.get(). Then add a click event through on():
var content = new Ext.Panel({
id: 'myPanel',
region:'center',
margins:'5 0 5 5',
cls:'empty',
bodyStyle:'background:ivory; font-size: 13pt',
html:'<p id="txest123">This is where the content goes for each selection.</p>'
});
Ext.get('myPanel').on('click', function() {alert('You clicked me');});
The following sample is a bit rough but it works for me. It is a panel with a box component, which is showing a thumbnail. When clicking on the thumbnail, it is showing a lightbox with slimbox2. Not pretty, but very effective. The hardcoded images are just for test here.
var panel = new Ext.Panel({
title : 'Image',
header : false,
frame : true,
border : false,
bodyStyle : 'padding : 5px',
width : 125,
items : [{
xtype : 'box',
height : 115,
width : 115,
listeners : {
'render': function() {
var id = Ext.id(this);
Ext.fly(id).addListener('click', function () {
jQuery.slimbox('thisisnotanimage', 'CBX');
});
}
},
autoEl: {
tag : 'div',
html : 'somehtmltagstuff'
}
}
]
});
According to the API, click is not a valid event for Panels... However, you should still be able to add the click event to the underlying DIV element.
Ext.fly(e.id).addListener('click', Ext.getCmp(e.id) , this);
I believe you need something like:
var content = new Ext.Panel({
region:'center',
margins:'5 0 5 5',
cls:'empty',
bodyStyle:'background:ivory; font-size: 13pt',
html:'<p id="test123">This is where the content goes for each selection.</p>',
listeners: {
click: function() {
alert('was clicked');
}
}
});

Extjs Dynamic Grid

I'm trying to create a dynamic grid using ExtJS. The grid is built and displayed when a click event is fired then an ajax request is sent to the server to fetch the columns, records and records definition a.k.a store fields.
Each node could have different grid structure and that depends on the level of the node in the tree.
The only way I came up with so far is :
function showGrid(response, request) {
var jsonData = Ext.util.JSON.decode(response.responseText);
var grid = Ext.getCmp('contentGrid' + request.params.owner);
if (grid) {
grid.destroy();
}
var store = new Ext.data.ArrayStore({
id: 'arrayStore',
fields: jsonData.recordFields,
autoDestroy: true
});
grid = new Ext.grid.GridPanel({
defaults: {
sortable: true
},
id: 'contentGrid' + request.params.owner,
store: store,
columns: jsonData.columns,
//width:540,
//height:200,
loadMask: true
});
store.loadData(jsonData.records);
if (Ext.getCmp('tab-' + request.params.owner)) {
Ext.getCmp('tab-' + request.params.owner).show();
} else {
grid.render('grid-div');
Ext.getCmp('card-tabs-panel').add({
id: 'tab-' + request.params.owner,
title: request.params.text,
iconCls: 'silk-tab',
html: Ext.getDom('grid-div').innerHTML,
closable: true
}).show();
}
}
The function above is called when a click event is fired
'click': function(node) {
Ext.Ajax.request({
url: 'showCtn',
success: function(response, request) {
alert('Success');
showGrid(response, request);
},
failure: function(results, request) {
alert('Error');
},
params: Ext.urlDecode(node.attributes.options);
}
});
}
The problem I'm getting with this code is that a new grid is displayed each time the showGrid function is called. The end user sees the old grids and the new one. To mitigate this problem, I tried destroying the grid and also removing the grid element on each request, and that seems to solve the problem only that records never get displayed this time.
if (grid) {
grid.destroy(true);
}
The behaviour I'm looking for is to display the result of a grid within a tab and if that tab exists replaced the old grid.
Any help is appreciated.
When you are trying to add your grid to the tab like this:
html:Ext.getDom('grid-div').innerHTML,
Ext is not aware of it being a valid grid component. Instead, you are simply adding HTML markup that just happens to look like a grid, but the TabPanel will not be aware that it is a grid component.
Instead you should add the grid itself as the tab (a GridPanel is a Panel and does not need to be nested into a parent panel). You can do so and also apply the needed tab configs like this:
Ext.getCmp('card-tabs-panel').add({
Ext.apply(grid, {
id: 'tab-' + request.params.owner,
title: request.params.text,
iconCls: 'silk-tab',
closable: true
});
}).show();
BTW, constantly creating and destroying grids is not an ideal strategy if you can avoid it. It might be better to simply hide and re-show grids (and reload their data) based on which type of grid is needed if that's possible (assuming the set of grid types is finite).
A potential option is to use the metaData field on the JsonStore that allows dynamic reconfiguring of the grid columns as per new datasets.

How to apply seriesStyles to piechart in ExtJs dynamically

Am trying to set 'seriesstyles' to piechart dynamically from the JSON data. When the 'oneWeekStore' loads the JSON data, I wish to iterate through the 'color' of each record and setSeriesStyles dynamically to PieChart. Below is the snippet.
var oneWeekStore = new Ext.data.JsonStore({
id:'jsonStore',
fields: ['appCount','appName'],
autoLoad: true,
root: 'rows',
proxy:storeProxy,
baseParams:{
'interval':'oneWeek',
'fromDate':frmDt.getValue()
},
listeners: {load: {
fn:function(store,records,options) {
/*I wish iterate through each record,fetch 'color'
and setSeriesStyles. I tried passing sample arrays
as paramater to setSeriesStyles like
**colors= new Array('0x08E3FE','0x448991','0x054D56');
Ext.getCmp('test12').setSeriesStyles(colors)**
But FF throws error "this.swf is undefined". Could
you please let me know the right format to pass as
parameter. */
}
});
var panel = new Ext.Panel{
id: '1week', title:'1 week',
items : [
{ id:'test12',
xtype : 'piechart',
store : oneWeekStore,
dataField : 'appCount',
categoryField : 'appName',
extraStyle : {
legend:{
display : 'right',
padding : 5,
spacing: 2, font :color:0x000000,family:
'Arial', size:9},
border:{size :1,color :0x999999},
background:{color: 0xd6e1cc}
} } } ] }
My JSON data looks below:
{"success":true,"rows":[{"appCount":"9693814","appName":"GED","color":"0xFB5D0D"},{"appCount":"5731","appName":"SGEF"","color":"0xFFFF6B"}]}
Your guidance is highly appreciated
You have a classic race condition there - your setting an event in motion that relies on a Component who's status is unknown.
The event your setting off is the loading of the data Store, when that has finished loading it is trying to interact with the Panel, but at that point we don't know if the Panel has been rendered yet.
Your best bet is to make one of those things happen in reaction to the other, for example:
1 ) load the store
2 ) on load event fired, create the panel
var oneWeekStore = new Ext.data.JsonStore({
id:'jsonStore',
...,
listeners: {
load:function(store,records,options) {
var panel = new Ext.Panel({
...,
seriesStyles: colors,
...
});
}
}
});
or
1 ) create the panel (chart)
2 ) on render event of the panel, load the store (remove autoLoad:true)
var panel = new Ext.Panel({
id: '1week',
...,
listeners: {
render: function(pnl){
oneWeekStore.load();
}
}
});
Hope that helps.
