positioning of a container in extjs - extjs

In my project, I am trying to position a container as absolute. but if I do so, it is also effecting the neighbour items. I mean, after positioning the container, if I give some width and height to that particular container, it is effecting all the toolbar. (which I don't want to happen). This effect is happening even if I use layout: 'absolute or css position:absolute.
Here is my related code:
xtype: 'panel',
dockedItems: [{
dock: 'top',
xtype: 'toolbar',
height: 40,
items: [
{
//only this should be absolute positioned
xtype: 'container',
cls: 'logo', //tried with applying css styles !important
//even tried with layout: 'absolute'
},'-',
//the below elements should not move their position
//even if the above one has been applied positioning.
{
xtype: 'container'
},'->',
{
xtype: 'container'
}]
}],
Here my goal is to bring the container out of the toolbar because it should have greater height than the toolbar keeping other containers constant.

If the profile pic container has to be higher than the toolbar, it can't be a child of the toolbar container.
You could create a container with absolute layout below the toolbar, in that container you will have the profile pic and you can use a negative Y variable in order to move up the image, so it looks like is in the toolbar.
Just like this
var toolbar = Ext.create('Ext.toolbar.Toolbar', {
items: [
{},
{ xtype: 'tbspacer', width: 50 }, // Moving the button to the right
{ text: 'Fake Name Button' }
]
});
Ext.create('Ext.container.Container', {
layout: 'fit',
width : 700,
renderTo: Ext.getBody(),
items: [toolbar]
});
var image = Ext.create('Ext.Img', {
x: 0,
y: -25,
maxWidth: 70,
src: 'https://twimg0-a.akamaihd.net/profile_images/1471554494/swel.png'
});
Ext.create('Ext.container.Container', {
layout: {
type: 'absolute'
},
renderTo: Ext.getBody(),
items: [image]
});

This solution is not so pretty, but it might work.

How to scroll container in EXT JS but only to specific component?

How to allow scrolling in extjs but only to some other component. For example, in the code below, the html component shouldn't go away from the screen.
Ext.create('Ext.Container', {
renderTo: Ext.getBody(),
scrollable: true,
items:[
{
xtype: 'datefield',
label: 'From',
},
{
xtype: 'datefield',
label: 'To',
},
{
padding: 50,
html: 'This should stick to the top',
height: 550,
},
{
xtype: 'grid',
height: 600,
scrollable: true
}
]
});
There is a few issues with your code. First, the container you add to the body is set to scrollable, set it to false if you don't want it scrolling.
Then you add it to the body element, even if it is not scrollable, its height will be the sum of its children, if that is taller than your body element, scrollbar will appear. But it is important to notice in this case what is scrolling is the body, not the component.
Then you said you want it to stick that html component on top, but what do you exactly mean by that? Make it appear above the two inputs? If you want that, add docked: 'top' to it.
Adding your container into a viewport instead of directly to body is a better approach, you can test this in sencha fiddle:
Ext.application({
name: 'Fiddle',
launch: function () {
const container = Ext.create('Ext.Container', {
scrollable: true,
items: [{
xtype: 'datefield',
label: 'From',
}, {
xtype: 'datefield',
label: 'To',
}, {
padding: 50,
html: 'This should stick to the top',
height: 550,
}, {
xtype: 'grid',
height: 600,
scrollable: true,
data: Array.from(Array(100).keys()).map(value=>({value})),
columns: [{text: 'value',dataIndex: 'value'}]
}]
});
Ext.Viewport.add(container);
}
});
Anyways, I don't really understand what are you trying to achieve, because if you set the outer component non-scrollable and put it into a component smaller than ~500px, how do you expect to see your grid? I suggest to take a

ExtJS resizable windows keeping aspect ratio

I am trying to resize windows in ExtJS 6, and they resize fine, but I would like to resize them whilst maintaining the aspect ratio, but so far after an extensive google search and trying many options, I cannot seem to find a solution.
I have a simple window with two panels in with textfield in one and a button in the other to begin with whilst I figure this out - below is a sample of the code in which I am trying to apply this to.
Ext.define('SenchaApp.view.MainView', {
extend: 'Ext.window.Window',
autoShow: true,
height: 600,
width: 600,
constrainHeader: true,
title: 'Main View',
items:[{
xtype: 'panel',
height: 200,
width: 600,
items:[{
xtype: 'displayfield',
text: 'my button'
}]
},
{
xtype: 'panel',
height: 200,
width: 600,
items:[{
xtype: 'button',
text: 'my button'
}]
}
]
});
Use the resizable config in your window which can be a config object of Ext.resizer.Resizer. The Resizer class has a preserveRatio config for exactly what you want.
resizable: {
preserveRatio: true
}
Here's a fiddle to demonstrate:

ExtJS: 'next to centre'

I'd like to achieve this in ExtJS 4.2:
e.g. a centred button, with something (a progress indicator) to its right that doesn't result in the button moving.
All my layouts are currently relative, largely using HBox & VBox, and I'd like to keep it this way rather than using anything absolute to solve this.
There are probably lots of ways to do this, but many of them will be horrible. I guess the 'floating' attribute might play a part, but I can't quite work that out.
Any suggestions?
Use the HBox layout's pack config to display the items in the center, and apply a margin equal to the progess bar's width to the left side of the button:
{
layout: {
type: 'hbox',
pack: 'center'
},
items: [{
xtype: 'button',
text: 'Push me',
width: 100,
margin: '0 0 0 100' // margin-left equal to the width of the progress bar
},{
xtype: 'progressbar',
width: 100
}]
}
Also check out this fiddle.
Here is my attempt, let me know if it's a problem.
Ext.onReady(function() {
var ct = new Ext.panel.Panel({
width: '100%',
renderTo: Ext.getBody(),
margin: 10,
border: true,
id: 'ppanel',
layout: {
type: 'hbox',
},
items: [{
xtype: 'button',
text: 'Push me',
width: 100,
id: 'bbutton'
},{
xtype: 'progressbar',
width: 100,
id: 'pbar'
}],
listeners: {
afterrender: function() {
pwidth = Ext.getCmp('ppanel').getWidth();
bwidth = Ext.getCmp('bbutton').getWidth();
button = Ext.getCmp('bbutton');
progrs = Ext.getCmp('pbar');
bmargin = (pwidth/2 - bwidth/2);
button.setMargin("0 0 0 "+bmargin);
progrs.setMargin("0 0 0 10");
}
}
});
});

Extjs : Toolbar inside a panel not resizing on Browser resize

I have a toolbar and a grid within a Panel. On resize, the grid looks good. However the toolbar maintains its original dimensions and does not resize causing a few buttons to hide .
How do I rectify this?
{
xtype: 'panel',
region: 'center',
layout: 'border',
tbar:[
{
xtype: 'buttongroup',
region: 'center',
items: getToolBarButtons() // method to add buttons to toolbar dynamically
}
],
items: [
{
xtype: 'tabpanel',
activeTab: 0,
layout: 'fit',
region: 'center',
disabled: 'true',
items:[
{
// grid 1
height : '80%',
width : '100%'
},
{
// grid 2
height : '80%',
width : '100%'
}
]
}
]
}
Edit:
I replaced tbar with dockedItems: [{ xtype:' toolbar' ...}] . The toolbar doesn't get rendered at all
Ext.toolbar.Toolbar can automatically transform overflowed toolbar buttons to menu with menu items. To allowed this automatic transformations you need to configure your toolbar component with config enableOverflow: true
So instead of tbar config use:
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
enableOverflow: true,
items: [
{
xtype: 'buttongroup',
items: getToolBarButtons()
}
]
}]
Also consider dividing buttons to more buttongroups. If toolbar has more buttongroups ExtJS toolbar can handle overflow with better results.

How to set a dynamic width in an vbox in ExtJS4?

I want the following layout (the chart count in the top right is dynamic):
I tried to take a border-layout for the main container. Chart1 is region: 'west' and the rest is in region: 'center'.
In the center, I got a vbox container, with 2 containers, one for the charts (top) and one is the grid (bottom)
The Problem is now, that these 2 containers want a fixed width, or else they get a zero width...
Also I want to have all the containers to be fluid, so I can resize everything without getting empty spaces.
I read about using flex: 1 if I want some containers in a vbox to to get a 100% width, but this didn't work. It just made the 2 containers in the vbox use the same height.
Any ideas?
How about something like this (quickly drawn in the architect):
Ext.define('MyApp.view.MyWindow', {
extend: 'Ext.window.Window',
height: 600,
width: 1000,
layout: {
align: 'stretch',
type: 'hbox'
},
title: 'My Window',
initComponent: function () {
var me = this;
Ext.applyIf(me, {
items: [{
xtype: 'container',
flex: 1,
layout: {
type: 'fit'
},
items: [{
xtype: 'chart'
}]
}, {
xtype: 'container',
flex: 4,
layout: {
align: 'stretch',
type: 'vbox'
},
items: [{
xtype: 'container',
flex: 1,
layout: {
align: 'stretch',
type: 'hbox'
},
items: [{
xtype: 'chart',
flex: 1,
}, {
xtype: 'chart',
flex: 1,
}, {
xtype: 'chart',
flex: 1,
}, {
xtype: 'chart',
flex: 1,
}]
}, {
xtype: 'gridpanel',
flex: 1,
title: 'My Grid Panel',
}]
}]
});
me.callParent(arguments);
}
});
Although that way the Flex value of the second container has to account for the amount of charts you're displaying horizontally.
Have you tried table layout? It's quite easy to create such layout with it. Example:
Ext.onReady(function(){
Ext.create('Ext.Viewport', {
renderTo: Ext.getBody(),
style: 'border: 1px solid red',
layout: {
type: 'table',
columns: 5,
tdAttrs: {
style: 'padding: 20px; border: 1px solid blue;'
}
},
defaults: {
bodyStyle: 'border: 1px solid red'
},
items: [
{ xtype: 'panel', html: 'Chart1', rowspan: 2 },
{ xtype: 'panel', html: 'Chart2' },
{ xtype: 'panel', html: 'Chart3' },
{ xtype: 'panel', html: 'Chart4' },
{ xtype: 'panel', html: 'Chart5' },
{ xtype: 'panel', html: 'Grid', colspan: 4 }
]
});
});
Working sample: http://jsbin.com/ojijax/1/
To have dynamic layout IMO the best solution is to use hbox and vbox layouts.
For example you can wrap charts from 2 to n into one container, let's say chartPanel - this will have hbox layout. Then wrap chartPanel and grid into another container - panel with vbox layout. Then again wrap chart1 with panel with hbox layout. Then you must set align: stretch for each box layout, and proper flex to divide screen equaly.
Working sample: http://jsfiddle.net/75T7h/
I think you are loading chart2, 3, 4 , 5 in a for loop using panel.add option of extjs (better way).
If so then keep a count of these panels (here 4) and for each panel while assigning width you give like
width:(1/countOfchrtLIst2345) * grid.getWidth(),
So whatever count comes it will divide available width between all these horizontal panels within your top vbox and allocates.
In your example it assigns
(1/4) * 200
(thinking grid has width of 200)
