I'm using ExtJS 3.3.2 and I have a panel with some panels nested in vbox and hbox. The problem is easy: My data from items inside hbox are not showing, I tried modifying weight and height but it never shows up. Looking at the code (F12), I see the data is created, but the panels have a very tiny size.
var i = 0;
jsonResp.forEach(function(currentItem) {
i++;
var panel = new Ext.Panel({
id: 'superpanel'+i,
layout: 'vbox',
height: 50,
frame: true,
collapsible: true,
items: [{
xtype: 'panel',
id: 'jsonObject'+i,
layout: 'hbox',
frame: true,
align: 'stretch',
items:[{
id: 'codigo'+i,
xtype: 'panel',
html: currentItem.codigo
},{
id:'nombre'+i,
xtype: 'panel',
html: currentItem.nombre
},{
xtype: 'panel',
html: currentItem.estado.toString()
}]
},{
xtype: 'panel',
id: 'aviso'+i,
html: "Error"
}]
})
Ext.getCmp("contenedor").add(panel);
});
Ext.getCmp("contenedor").doLayout();
I want to create this:
What is wrong? I tried it with width/height and flex but it doesn't work.
width: "100%" and flex can be used to resolve this issue.
Here is how I resolved it.
Ext.onReady(function () {
var viewport = new Ext.Viewport({
items: [{
xtype: "panel",
title: "Test one",
width: 500,
height: 800,
id: "contenedor",
autoScroll: true
}]
});
//delay for adding dynamic content
setTimeout(function () {
var parentPanel = Ext.getCmp("contenedor");
for (var i = 0; i < 10; i++) {
var panel = new Ext.Panel({
id: 'superpanel' + i,
layout: 'vbox',
height: 100,
frame: true,
collapsible: true,
items: [{
xtype: 'panel',
id: 'jsonObject' + i,
layout: 'hbox',
frame: true,
align: 'stretch',
flex: 3,
width: '100%',
items: [{
id: 'codigo' + i,
flex: 1,
xtype: 'panel',
html: 'Demo html 1'
}, {
id: 'nombre' + i,
xtype: 'panel',
flex: 1,
html: 'Demo html 2'
}, {
xtype: 'panel',
flex: 1,
html: 'Demo html 3'
}]
}, {
xtype: 'panel',
id: 'aviso' + i,
html: "Error",
width: "100%"
}]
});
parentPanel.add(panel);
}
parentPanel.doLayout();
}, 2000);
});
Fiddle is created with ExtJS 3.4.1.1. Sadly there is no 3.2.2 version available on sencha fiddle. But this should work with 3.2.2.

I have a docked panel in which am changing the dock position using the setDock method. In that docked panel, I also have collapsible buttons which should change as per to the dock position. I am updating the configs collapseDirection and expandDirection and calling out a method updateCollapseTool which lets me update the button.
But I get an issue after the following steps:
Change the dock position to left using the menu button.
Collapse the docked panel using the collapse button, then again expand it.
Again change the dock position to top.
Collapse the docked panel again => After this step my docked panel gets collapsed, but it seems to be collapsed in left direction. It should have collapsed to top and should show an expand button pointing in bottom direction.
If I perform the same steps by excluding the step 2, it works properly. Is there anything that am doing wrong or any other methods which lets me update my expand/collapse buttons properly ?
Here is my fiddle link.
You can use border layout and the the region with setRegion method, something like this:
Ext.application({
name: 'Fiddle',
launch: function () {
Ext.create({
scrollable: true,
id: 'parentPanel',
xtype: 'panel',
height: 500,
layout: 'border',
items: [{
xtype: 'panel',
id: 'dockPanel1',
region: 'north',
title: 'Parent Dock Panel',
collapsible: true,
collapseFirst: false,
width: 300,
height: 200,
defaults: {
style: {
background: "orange",
border: "1px"
},
},
layout: "container",
tools: [{
text: "dock change",
xtype: 'button',
value: 'top',
menu: {
items: [{
text: 'top',
region: 'north'
}, {
text: 'left',
region: 'west'
}, {
text: 'right',
region: 'east'
}],
listeners: {
click: function (menu, item, e, eOpts) {
Ext.getCmp('dockPanel1').setRegion(item.region);
}
}
}
}],
items: [{
xtype: 'textfield',
text: 'item 1'
}, {
xtype: 'textfield',
text: 'item 2'
}, {
xtype: 'textfield',
text: 'item 3'
}]
}, {
xtype: 'panel',
region: 'center',
layout: "vbox",
items: [{
html: "<span style='font-size:20px;'>Child panel 1</span>",
bodyStyle: "background: lightgreen;",
xtype: 'panel',
height: "50%",
width: "70%",
padding: "5 5",
cls: 'overlayMenuCls'
}, {
html: "<span style='font-size:20px;'>Child panel 2</span>",
bodyStyle: "background: lightblue;",
xtype: 'panel',
height: "50%",
width: "70%",
padding: "5 5",
cls: 'overlayMenuCls'
}]
}],
renderTo: Ext.getBody()
});
}
});
Ext.application({

launch: function() {
var mainView = new Ext.panel.Panel({

listeners:
{
click: function(btn, e, eOpts)
{

}
},
},
]
},
]
}],
renderTo: Ext.getBody()
});
}
});
Sencha provides an "Admin Dashboard" example application when you download the framework, that implements collapsible side navigation. All the source code for the below layout (and every component found in the kitchen sink) can be found in the framework download.

This isn't something you should be recreating yourself (defeats the point of using a framework like Extjs)
I have a Ext window in that having two items container and fieldset. For container and fieldset I am geting data in form of html from server.
If this data is big, scrollbar appears not navigate the text completly.
How can I configure a vertical scrollbar properly in this panel ?
My sample code is :
Ext.create('Ext.window.Window', {
title: 'DataSet',
bodyPadding: 5,
modal: true,
height: 600,
width: 900,
layout: 'fit',
items: {
xtype: 'form',
items: [{
xtype: 'container',
html: jsonData.R.ErrorMsg || ''
}, {
xtype: 'fieldset',
padding: '5 0 10 0',
collapsible: true,
title: 'Description',
autoScroll: true,
height: 580,
width: 880,
collapsed: true,
overflowY: 'scroll',
html: Ext.String.htmlEncode(jsonData.R.ErrorDesc) || ''
}]
}
})
The problem is that you are setting fixed width and height to the fieldset. If you want to have the scrollbar only when the content exceed the window size you first need to set the fieldset size as flex.
Use vbox layout in form
Replace fixed height: 580 and width: 880 with flex: 1 in fieldset
Here is a working fiddle: https://fiddle.sencha.com/#view/editor&fiddle/30f9
Fieldset is not meant to be a form element(displaying html), It is meant to be a container for grouping sets of fields.
Creating a fieldset with child item text area or text field
Ext.create('Ext.window.Window', {
title: 'DataSet',
bodyPadding: 5,
modal: true,
height: 600,
width: 900,
layout: 'fit',
items: {
xtype: 'form',
items: [{
xtype: 'container',
html: jsonData.R.ErrorMsg || ''
}, {
xtype: 'fieldset',
collapsed: true,
overflowY: 'scroll',
items: [
{
xtype: 'textfield',
padding: '5 0 10 0',
collapsible: true,
title: 'Description',
height: 580,
width: 880,
itemId: 'errorDesc',
name: 'errorDesc',
fieldLabel: 'Error Desc',
value: Ext.String.htmlEncode(jsonData.R.ErrorDesc) || ''
}
}]
}
})
The height of the parent container i.e "Ext.window.Window" is fixed at 600. You can try giving it at '100%' increasing its height.
Ext.create('Ext.form.Panel', {
title: 'Simple Form with FieldSets',
labelWidth: 75, // label settings here cascade unless overridden
url: 'save-form.php',
frame: true,
bodyStyle: 'padding:5px 5px 0',
width: 550,
renderTo: Ext.getBody(),
layout: 'column', // arrange fieldsets side by side
items: [{
// Fieldset in Column 1 - collapsible via toggle button
xtype:'fieldset',
columnWidth: 0.5,
title: 'Fieldset 1',
collapsible: true,
defaultType: 'textfield',
defaults: {anchor: '100%'},
layout: 'anchor',
items :[{
xtype:'container',
html: Ext.String.htmlEncode("<input type=\"text\"> Hello </input>")
}, {
fieldLabel: 'Field 2',
name: 'field2'
}]
}]});
Here height is not specified and parent container's height will be based on the items it holds.
You can try this it works:
Ext.create('Ext.window.Window', {
title: 'DataSet',
bodyPadding: 5,
modal: true,
height: 600,
width: 900,
layout: 'fit',
items: {
xtype: 'form',
items: [{
xtype: 'container',
html: jsonData.R.ErrorMsg || ''
}, {
xtype: 'fieldset',
padding: '5 0 10 0',
collapsible: true,
title: 'Description',
height: 580,
width: 880,
collapsed: true,
overflowY: 'scroll',
html: Ext.String.htmlEncode(jsonData.R.ErrorDesc) || ''
}]
}
})
I have the following application and it fills the screen no problem horizontally. I would like it to fill out vertically as well.
var missionsPanel = new Ext.panel.Panel
(
{
title: 'Active Missions', width: '35%', renderTo: Ext.getBody(), layout: { type: 'vbox', align: 'stretch', padding: 5}
}
);
resultsPanel = Ext.create('Ext.panel.Panel', {
title: 'ISR Toolkit v3.0',
renderTo: Ext.getBody(),
layout: { type: 'hbox', align: 'fit', padding: 5 },
items:
[ missionsPanel, { xtype: 'splitter' },
{ title: 'Person Details', bodyPadding: 5, flex: 2,
items:
[
{ itemId: 'txtName', fieldLabel: 'Name:', xtype: 'textfield'},
{ itemId: 'txtAge', fieldLabel: 'Age', xtype: 'textfield'},
{ itemId: 'btnShow', xtype: 'button', height: '60', width: 125, align: 'right', text: 'Show Data', handler: createNewMissionWindow }
]
}
]
});
I am sure it's something small I a missing.
The easiest way would be to create a Viewport with a fit layout, and the only item being your panel (removing the renderTo configs, as well as any height/width).
I am new to extJS. I want to bind a Ext.grid.Panel to Ext.Panel (yes, I really want that!). This is what I've tried -
Var Panel = new Ext.Panel({
title: 'Test',
id: 'Panel',
items: [Grid]
});
Var Grid =
{
xtype: 'grid',
columns: [
{ header: 'Resort', dataIndex: 'resort' },
{ header: 'Arrival', dataIndex: 'arrival' },
{ header: 'Accompanying Guest(s)', dataIndex: 'guest', flex: 1 }
]
};
Now I want to open Panel in a Ext.Window
var win2 = new Ext.Window({
layout: 'fit',
width: 900,
height: 600,
closeAction: 'hide',
plain: true,
items: [Panel]
});
b.getEl().on('click', function () {
win2.show();
});
This ends in an error - Uncaught TypeError: Cannot read property 'events' of undefined
But when I change the Panel as below, its working fine-
var Panel = new Ext.Panel({
title: 'Test',
id: 'Panel',
items:
[
{
xtype: 'grid',
columns: [
{ header: 'Resort', dataIndex: 'resort' },
{ header: 'Arrival', dataIndex: 'arrival' },
{ header: 'Accompanying Guest(s)', dataIndex: 'guest', flex: 1 }
]
}
]
});
What went wrong in my previous code?
Of course it doesn't work. You're essentially doing this:
var y = x + 1;
console.log(y); // Why isn't y 2?
var x = 1;
Either you have to define your grid before you use it in items as below :
var Grid = {
xtype: 'grid',
columns: [{
header: 'Resort',
dataIndex: 'resort'
}, {
header: 'Arrival',
dataIndex: 'arrival'
}, {
header: 'Accompanying Guest(s)',
dataIndex: 'guest',
flex: 1
}]
};
var Panel = new Ext.Panel({
// title: 'Test',
id: 'Panel',
items: [Grid]
});
Or else one more option is (When you have grid in different js file you can go with listeners as done below ) :
var Panel = new Ext.Panel({
// title: 'Test',
id: 'Panel',
items: [],
listeners: {
render: function(pnl) {
pnl.add(Grid);
}
}
});
var Grid = {
xtype: 'grid',
columns: [{
header: 'Resort',
dataIndex: 'resort'
}, {
header: 'Arrival',
dataIndex: 'arrival'
}, {
header: 'Accompanying Guest(s)',
dataIndex: 'guest',
flex: 1
}]
};
var win2 = new Ext.Window({
layout: 'fit',
width: 500,
height: 400,
closeAction: 'hide',
plain: true,
items: [Panel]
});
b.getEl().on('click', function() {
win2.show();
