I have a panel with a "form" layout, containing several buttons. now I want to enable this panel resize according to window resizing. How can I get this done?
thanks.
Ext.EventManager.onWindowResize(function(w, h){
panel.doComponentLayout();
});
Assuming you have a Panel named 'panel' with some automatic sizing built in (e.g. height: "100%"). Otherwise, the new width and height of the window are passed into the anonymous function passed to onWindowResize().
As wrote #deniztt you should subscribe to EventManager class onWindows Resize Event.
It can be something like this:
Ext.EventManager.onWindowResize(function () {
var width = Ext.getBody().getViewSize().width - 160;
var height = Ext.getBody().getViewSize().height - 140;
panel.setSize(width, height);
});
Where panel is reference to your panel
You can read about it here.
You can make the panel resizable by setting the 'resizable' config option, see the docs for the various options: http://dev.sencha.com/deploy/ext-4.0.0/docs/api/Ext.panel.Panel.html.
As far as how the form components interact you'll need to set anchor's if you want to use a form layout or switch to an hbox/vbox type of set-up with various flex settings.
You can set the size for window and set the child panel's autoHeight and autoWidth attributes true.
Another way is catching the resize event of the window and resize the child panel according to the new size values.
Thanks to Gegory and Joseph for the EventManager solution. I've done some minor changes to this solution, replacing the getBody() with a DIV and setting an initial width/height of my chart (or any other component):
<div id="chart" style="overflow: hidden; position:absolute; width:100%; height:90%;"></div>
....
Ext.onReady(function() {
var renderDiv = Ext.get('chart_div');
var chart = Ext.create('Ext.chart.Chart', {
renderTo: renderDiv,
width: renderDiv.getWidth(),
height: renderDiv.getHeight() - 50,
...
});
Ext.EventManager.onWindowResize(function () {
var height = renderDiv.getHeight() -50;
var width = renderDiv.getWidth();
chart.setSize(width, height);
});
});
autoWidth and autoHeight don't seem to work for me (Ext-JS 4.2.1).

I am facing problem with c3 charts sizing issue with in gridster. Can any one help me how can I make there charts to be properly auto resized according to the gridster box they are in? Please find the Plunker
I have given size in options :
size: {
height: 100,
width: 100
}
If I remove this size property the charts are going out of box. But they are too small in gridster boxes. How can I make these chart to automatically occupy the full height and width of the gridster boxes that they are in?
The options you are using:
size: {
height: 100,
width: 100
}
are setting the height and width of the svg element to 100px instead of 100%
I tried
size: {
height: '100%',
width: '100%'
}
Which will successfully set the width to 100% but somehow the height will be set to 320px
So if you add this to your css:
.c3 svg {
width: 100%;
height: 100%;
}
That will solve your sizing issue.
EDIT
Just a small change to set up an initial size and some comments added to your controller on the resize - stop event handler, where you will need to add some resizing of your charts based on the new sizes. See it here
resizable: {
enabled: true,
handles: ['n', 'e', 's', 'w', 'ne', 'se', 'sw', 'nw'],
// optional callback fired when resize is started
start: function(event, $element, widget) {},
// optional callback fired when item is resized,
resize: function(event, $element, widget) {},
// optional callback fired when item is finished resizing
stop: function(event, $element, widget) {
// here should update the size according to the widget size
// widget.sizeX (* 160px) and widget.sizeY (* 160px)
// and further adjustments
}
},
I had a similar problem not long ago. What I did is use scale(), but it doesn't work on firefox.
Basically find the width when loading, and make a new scale when the user changes the screen size (or any other event like resizing your containers).
add this at the bottom of your plunker :
<script>
let width = window.innerWidth;
window.addEventListener('resize', (event) => {
let newWidth = window.innerWidth;
let ratio = newWidth / width;
let ctnr = document.getElementById('widget1');
ctnr.style.transform = "scale(" + ratio + ")";
});
</script>
That will scale widget 1. Of course you might have to play with the numbers a bit to find what works for you.
The widget will stay in place however; thus if you want it to be aligned on the left you can use in your css :
transform-origin: 0;
I hope this helps.
Use nvd3 plugin this is same as c3 plugin also this smoothly works with gridster, Please find the below link

I'm having problems with isotope in my site. I thought I tackled them all but now there is still a problem when resizing the window. On resize of the window the whole grid is moved way down on the page. This is not fixed by re-doing the layout when the window size changes. Triggering a .isotope('layout') always moves the whole grid to the bottom of the page. My code also implements infinite scroll, that is why I have the part on the hiddenelem's children. I'm also using bootstrap btw.
The (important) part of the code:
if (typeof g_Isotopegrid === 'undefined') {
g_Isotopegrid = $('.grid').isotope({
itemSelector: '.grid-item',
stamp: '.stamp',
masonry: {
columnWidth: 255,
gutter: 30
}
});
}
// Append all the hidden items to the visible items element
hiddenElm.children().each(function () {
var aItem = $(this);
// Append the items to the visible div
aItem.appendTo(visibleElm).imagesLoaded(function() {
g_Isotopegrid.isotope('appended', aItem);
});
});
Any help is appreciated!
In Bootstrap I never set static width:
masonry: {
columnWidth: 255,
gutter: 30
}
just item's class:
masonry: {
columnWidth: '.grid-item',
gutter: 30
}
When you are using Bootstrap is better for item width use bootstrap's classes.
The problem was that we were not using the direct container of the grid items as the element to apply isotope to.
I am using purecss to make a responsive website. In my page I have a HEADER and FOOTER; both of them are fixed and in between them I have CONTENT which has left vertical menu and the right side has some content.
Now what I want to achieve is when any resizing happens then my left side menu should have a scroll bar like of its own and the content in the right should also have one. Plus the menu div should not go mix with the footer or the header.
I am not very sure but do I need to use mobile-webkits to resolve this issue.
I have found something to help:
http://filamentgroup.github.io/Overthrow/examples/2-column/
Is this the only way or are there any other libraries which can help me in this?
UPDATED FIDDLE
Basically, I added in JQuery with functions to change the height of the left hand menu on resize. That, combined with the overflow from Y forces it to have scroll bars.
Onload:
$(function() {
var menuWrapper = $("#menu");
var height = $(window).height() - $("#header").height() - $("#footer").height();
menuWrapper.css("height", height);
});
On Resize:
$(window).on('resize', function(){
var menuWrapper = $("#menu");
var height = $(window).height() - $("#header").height() - $("#footer").height();
menuWrapper.css("height", height);
});
CSS:
#menu {
overflow-x: hidden;
overflow-y: auto;
}
Using Ext JS 4.0.2, I'm trying to open a window that automatically sizes itself big enough to fit its content, until it hits a height limit, at which point it stops getting bigger and shows a scroll bar.
Here's what I'm doing
Ext.create('widget.window', {
maxHeight: 300,
width: 250,
html: someReallyBigContent,
autoScroll: true,
autoShow: true
});
When the window is first rendered, it's sized big enough for the really big content--bigger than the maxHeight should allow. If I attempt to resize it, then snaps down to the maxHeight of 300px.
How do I constrain the window to its maxHeight when it's initially rendered?
I have exactly the same problem and for now I'm doing a litle dirty hack :)
this.on('afterrender', function() {
if (this.getHeight() > this.maxHeight) {
this.setHeight(this.maxHeight);
}
this.center();
}, this);
Depending on the content of the window, you must use the afterlayout event. Instead of using this.maxHeight, to use the whole viewport, use Ext.getBody().getViewSize().height or in vanilla JS use window.innerHeight.
This version will work even if the windows contains other components and not only huge html:
listeners: {afterlayout: function() {
var height = Ext.getBody().getViewSize().height;
if (this.getHeight() > height) {
this.setHeight(height);
}
this.center();
}}
This can be better :
bodyStyle: { maxHeight: '100px' }, autoScroll: true,
I don't see an out-of-the-box way to do this. However, you might try this approach:
Place the contents of the window into a container inside the window (i.e. make someReallyBigContent be inside a container.) On afterrender, get the height of that inner container and then proceed to set the height of the outer window based on that.
How I ended up displaying a window with an unknown amount of fields on a form (constrain = body.el):
prefForm.itemId = 'prefForm';
win = Ext.create('Ext.window.Window', {
layout : {
type : 'vbox',
align : 'center'
},
buttons : buttons,
maxHeight : constrain.dom.clientHeight - 50,
title : title,
items : prefForm,
listeners : {
afterrender : {
fn : function(win) {
var f = win.down('#prefForm');
f.doLayout();
var h = f.body.dom.scrollHeight;
if (f.getHeight() > h)
h = f.getHeight();
win.setHeight(h + 61);
win.center();
},
single : true
}
}
});
You can add this config on your window
maximizable: true
if you want you could programmatically 'click' that button :)
Now I see what you are trying to do. I think the only thing missing from your config is the height parameter. Set it to the same number as maxheight. That should do it, you won't need to call setHeight().
This is just like Ivan Novakov answer, except I prefer it when you override the onRender class for these types of classes.
This is for a couple of reasons. Removes an additional event listener, and in the case you have multiple things that need to occur at afterrender time. You can control the synchronization of these tasks.
onRender: function(ct,pos) {
//Call superclass
this.callParent(arguments);
if (this.getHeight() > this.maxHeight) {
this.setHeight(this.maxHeight);
}
this.center();
}
I had the little bit different problem. In my case ExtJS code there inside the HTML popup windows. And I had to achieve:
change the size of panel when we change the size of popup windows.
Ivan Novakov's solution worked for me.
Ext.EventManager.onWindowResize(function () {
var width = Ext.getBody().getViewSize().width - 20;
var height = Ext.getBody().getViewSize().height - 20;
myPanel.setSize(width, height);
});
I'm using the array-grid extjs example to try and fit a gridpanel into a container window. The problem is on resizing the container window, the gridpanel doesn't automatically fit the new size. As I understand it that's how it's supposed to work.
Here's the link to the example: http://www.extjs.com/deploy/dev/examples/grid/array-grid.html
What I've done is changed the following..
// Added to gridpanel config
layout: 'fit',
viewConfig: {
forceFit: true
}
// Window container
var gridWindow = new Ext.Window({
items: [
grid
]
});
// Instead of grid.render, use gridWindow.show();
gridWindow.show();
layout: 'fit',
should go into the gridWindow configuration! The layout manager arranges the children of a panel, but the grid is the child.
I'm using the following workaround:
Ext.onReady(function () {
var grid = ... //define your grid here
Ext.EventManager.onWindowResize(function () {
grid.setSize(undefined, undefined);
});
});
Extjs v4.0.7
I solved this by wrapping my gridpanel into an Ext.Panel, with a layout property set to 'fit'.
The grid panel (with a viewConfig also containing forceFit: 'true' now is resized automatically when the window is resized
I think you need to use EventManager class. Please read it in following blog
Using ExtJS 6, this is what worked for me (doesn't need a Ext.Viewport as parent container):
var grid = //...
Ext.on('resize', function(w, h){
grid.updateLayout();
});
