I have the ExtJS form which is floating
Now i want to give % margin from top and left but its not working.
Example is here :
https://fiddle.sencha.com/#fiddle/1dj
var f = new Ext.form.Panel({
width: 400,
height: 400,
title: 'Foo',
floating: true,
closable : true,
y: '10%',
x: '10%',
});
f.show();
Try the below for size:
var leftPercent=10;
var rightPercent=10;
// Create a viewport, this automatically scales to the window height/width so is predictable in its size
var viewport=Ext.create('Ext.container.Viewport', {
items:[
f
],
listeners:{
resize:function(){
// if the form has been added to the viewport, change its position
f && f.setPosition(viewport.getWidth()*(rightPercent/100), viewport.getHeight()*(rightPercent/100));
}
}
});
var f = new Ext.form.Panel({
width: 400,
height: 400,
title: 'Foo',
autoShow:true,
floating: true,
// set the initial position of the form (not necessarily needed)
x:viewport.getWidth()*(rightPercent/100),
y:viewport.getHeight()*(rightPercent/100)
});
It should provide you a decent basis to improve/edit. The important things are:
The window is placed within a component/element which is known (e.g. the viewport per above)
The height/width of the parent container behave as predicted during user interaction with the view
Any alterations to the height width of the parent container, then lead the child container to reposition itself accordingly
You can change the position of Ext.form.Panel by using setPosition() function.
Eg:-
var f = new Ext.form.Panel({
width: 400,
height: 400,
title: 'Foo',
floating: true,
closable : true,
y: '10%',
x: '10%',
});
f.show();
f.setPosition(100, 200, true);
Please refer below code.
Config:
region -> Defines the region inside
padding -> Specifies the padding for this component
var f = new Ext.form.Panel({
width: 400,
height: 400,
title: 'Foo',
floating: true,
closable : true,
//padding : '10 0 0 20', // example: '10 0 0 20' (top, right, bottom, left).
region : 'center' // possible values north, south, east, west, and center
});
f.show();
Note: padding used for smaller variation.
Second try :
var f = new Ext.form.Panel({
width: 400,
height: 400,
title: 'Foo',
floating: true,
closable : true,
left : 10,
top : 10
});
f.show();

I am attempting to render a Google bar chart. In my JavaScript, I have the following:
var options = {
width: '100%',
height: '100%',
chartArea: {
height: '100%',
width: '100%',
left: 85,
top: 10,
bottom: 60,
right: 25
},
legend: { position: 'bottom', alignment: 'start' },
annotations: { alwaysOutside: true},
hAxis: {
gridlines: { count: 10 },
},
};
When I execute this, I get the following JavaScript errors:
However, if I change the height from '100%' to '400' as shown below, the chart renders correctly with no JS errors.
var options = {
width: '100%',
height: '400',
chartArea: {
height: '100%',
width: '100%',
left: 85,
top: 10,
bottom: 60,
right: 25
},
legend: { position: 'bottom', alignment: 'start' },
annotations: { alwaysOutside: true},
hAxis: {
gridlines: { count: 10 },
},
};
If it matters, the div that represents the chart is in a Bootstrap container. The HTML looks as follows:
<div id="chart_div" class="col-xs-12 col-md-6">
</div>
The issue is here that google chart width and height expect a number, but you are sending a string including the % symbol, this is what the NaN error is, its Not a Number!
EDIT
Apologies, the documents state it can be either a number or string, my guess is that it is trying to convert it to a string and the % causes the error
chartArea.width
Type: number or string
Default: auto
chartArea.height
Type: number or string
Default: auto
https://developers.google.com/chart/interactive/docs/gallery/barchart#configuration-options
Edit 2
I was actually looking at the chartArea.height and not height.
The documentation states that the height and weight should be in pixels, so a number
height
Height of the chart, in pixels.
Type: number
Default: height of the containing element
width
Width of the chart, in pixels.
Type: number
Default: width of the containing element
So I cant really answer your original question, why the chart will accept a string is a mystery, when it is clearly defined as requiring a number.
I'm creating a web application and I want a panel to be perfectly in the center of it's parent panel. I was going through ExtJS5's Kitchen Sink to find layout examples and I found this one.
It places the panel perfectly in the middle, it doesn't cheat using hbox or vbox then setting the pack and align properties to center and middle.
Here is the code he used:
Ext.define('KitchenSink.view.layout.Center', {
extend: 'Ext.container.Container',
requires: [
'Ext.layout.container.Center'
],
xtype: 'layout-center',
width: 500,
height: 400,
layout: 'center',
items: {
title: 'Centered Panel: 75% of container width and 95% height',
border: true,
layout: 'center',
scrollable: true,
width: '75%',
height: '95%',
bodyPadding: '20 0',
items: [
{
title: 'Inner Centered Panel',
html: 'Fixed 300px wide and full height. The container panel will also autoscroll if narrower than 300px.',
width: 300,
height: '100%',
frame: true,
bodyPadding: '10 20'
}
]
}
});
And here is how it looks like:
The reason I prefer this is because the width and height of one the first inner panel is purely percent based. If I tried this using hbox or vbox, I would need to set the width or height to a fixed number.
I'm using Sencha Architect and for some reason, I can't find the layout type center for my panel, container, and viewport elements. I've also included the Ext.layout.container.Center in my requires but still no dice.
Does anyone know how to implement this Kitchen Sink example in Sencha Architect?
This is a bug https://www.sencha.com/forum/showthread.php?293050
But you can easily overcome any such problems using process config function in SA.
Select your class where you want to edit special configs and click on add processCofnig
Next in the generated function you can edit the configs in any way you need.
processMyContainer: function(config) {
config.layout = "center";
}
The only disadvantage of using process config is that you will not see the settings set by it in the SA design view - but when you preview the app you will see it.
This is my final code for the class:
Ext.define('MyApp.view.MyContainer', {
extend: 'Ext.container.Container',
alias: 'widget.mycontainer',
requires: [
'MyApp.view.MyContainerViewModel',
'Ext.panel.Panel'
],
viewModel: {
type: 'mycontainer'
},
height: 800,
width: 600,
initConfig: function(instanceConfig) {
var me = this,
config = {
items: [
me.processMainPAnel({
xtype: 'panel',
height: '95%',
width: '75%',
bodyPadding: '20 0',
title: 'Centered Panel: 75% of container width and 95% height',
items: [
{
xtype: 'panel',
height: '100%',
html: 'Fixed 300px wide and full height. The container panel will also autoscroll if narrower than 300px.',
width: 300,
bodyPadding: '10 20',
title: 'Inner Centered Panel'
}
]
})
]
};
me.processMyContainer(config);
if (instanceConfig) {
me.getConfigurator().merge(me, config, instanceConfig);
}
return me.callParent([config]);
},
processMainPAnel: function(config) {
config.layout = "center";
return config;
},
processMyContainer: function(config) {
config.layout = "center";
}
});
This is the result in the browser:
I have follow structure:
TabPanel->FormPanel->Grid
And i want to set grid's height to all free space on formpanle. If i says layout:fit` in FormPanle first textfield get all space of formpanel. How to do what i want?
FormPanel:
var search = new Ext.FormPanel({
labelAlign: 'top',
frame:true,
title: 'Поиск',
//layout:'fit',
viewConfig:{ forceFit: true },
//bodyStyle:'padding:5px 5px 0',
GridPanel:
var searchTab = new Ext.grid.GridPanel({
store: searchStore,
region: 'center',
cm: searchCm,
layout:'fit',
selModel: new Ext.grid.RowSelectionModel(),
stripeRows : true,
height: 390,
autoExpandColumn:'expColumn',
loadMask: true,
id: 'searchTab',
title:'Найденные объекты',
autoScroll: true,
User borderLayout and devide in 2 Region.North and center. Add your top panel content in north region and grid in center region.
layout: 'border',
items: [{
title: 'North Region is resizable',
region: 'north', // position for region
xtype: 'panel',
height: 100
},{
title: 'Center Region',
region: 'center', // center region is required, no width/height specified
xtype: 'panel',
layout: 'fit',
items: {
new Ext.grid.GridPanel({
store: searchStore,
region: 'center',
cm: searchCm,
layout:'fit',
selModel: new Ext.grid.RowSelectionModel(),
stripeRows : true,
height: 390,
autoExpandColumn:'expColumn',
loadMask: true,
id: 'searchTab',
title:'????????? ???????',
autoScroll: true
})
}
}]
Fix the height for textfield and Try height:'100%' for gridpanel. Sushant Jain's solution is good but in that too go for height:'100%' if you want grid to occupy leftover area. region: 'center' helps to occupy leftover area by north region but if you fix height or width than even if center region expand to occupy left over area grid panel will remain on fixed height.
I'm trying to create a layout in ExtJS which has a grid on top and on the bottom left and right sections, a basic parent/child, master/details layout:
wrapper_panel
panel_top
[grid]
panel_bottom
[left_area right_area]
However, the two areas in panel_bottom are on top of each other instead of to the left and right
var left_area = new Ext.Panel({
region: 'west',
layout: 'fit',
width: 100,
items: []
});
var right_area = new Ext.Panel({
region: 'center',
layout: 'fit',
width: 100,
items: []
});
var panel_bottom = new Ext.Panel({
//layout: 'border',
region: 'south',
items: [ left_area, right_area ]
})
It looks like this:
If I make the panel_bottom layout: border then the left and right areas disappear completely.
What do I need to change in the bottom area panels so that they line up left and right?
Addendum
#vimvds, if I add width: 200 or e.g. width: 300, I just get this:
Thanks for the answers, it led me to scrap this and use the table layout instead, which led me to another question how to define percentage instead of absolute values for height/width.
I'd use a Ext.layout.HBoxLayout:
var panel_bottom = new Ext.Panel({
layout: {
type: 'hbox',
align: 'stretch'
},
defaults: {
flex: 1
},
items: [ left_area, right_area ],
});
Alternatively you could also use a Ext.layout.TableLayout or a Ext.layout.ColumnLayout:
var panel_bottom = new Ext.Panel({
layout: 'column',
defaults: {
columnWidth: 0.5
},
items: [ left_area, right_area ],
});
And what happens if you use :
var panel_bottom = new Ext.Panel({
layout: 'border',
items: [ left_area, right_area ],
width: 200
});
Using ExtJs.
I'm trying to design a main which is divided into three sub panels (a tree list, a grid and a panel). The way it works is that you have a tree list (west) with elements, you click on an element which populates the grid (center), then you click on an element in the grid and that generates the panel (west).
My main panel containing the three other ones has been defined with a layout 'border'.
Now the problem I face is that the center layout (the grid) has been defined in the code with a fixed width and the west panel as an auto width. But when the interface gets generated, the grid width is suddenly taking all the space in the interface instead of the west panel.
The code looks like that:
var exploits_details_panel = new Ext.Panel({
region: 'east',
autoWidth: true,
autoScroll: true,
html: 'test'
});
var exploit_commands = new Ext.grid.GridPanel({
store: new Ext.data.Store({
autoDestroy: true
}),
sortable: true,
autoWidth: false,
region: 'center',
stripeRows: true,
autoScroll: true,
border: true,
width: 225,
columns: [
{header: 'command', width: 150, sortable: true},
{header: 'date', width: 70, sortable: true}
]
});
var exploits_tree = new Ext.tree.TreePanel({
border: true,
region: 'west',
width: 200,
useArrows: true,
autoScroll: true,
animate: true,
containerScroll: true,
rootVisible: false,
root: {nodeType: 'async'},
dataUrl: '/ui/modules/select/exploits/tree',
listeners: {
'click': function(node) {
}
}
});
var exploits = new Ext.Panel({
id: 'beef-configuration-exploits',
title: 'Auto-Exploit',
region: 'center',
split: true,
autoScroll: true,
layout: {
type: 'border',
padding: '5',
align: 'left'
},
items: [exploits_tree, exploit_commands, exploits_details_panel]
});
Here 'var exploits' is my main panel containing the three other sub panels.
The 'exploits_tree' is the tree list containing some elements. When you click on one of the elements the grid 'exploit_commands' gets populated and when you click in one of the populated elements, the 'exploits_details_panel' panel gets generated.
How can I set a fixed width on 'exploit_commands'?
Thanks for your time.
The center region cannot, according to the docs, have a fixed width (see the first bullet point under the Notes heading). Any other region (N, S, E or W) may define its size, and the center region simply takes up whatever space is left over. BTW, this is pretty much a standard approach for this style of layout in other GUI platforms too (or think of just about any graphical IDE you've used as an example).
Don't set auto width on your east panel, give it a defined starting width (otherwise it will not show, which is probably what you're seeing).
