Just started using progressbarwidget, I want the text from my textTpl to be center aligned within the progress bar at all times regardless of what percentage the bar is at, when I mean centered I mean the center of the progress bar and not center of the progress value. See fiddle below and attached image
https://fiddle.sencha.com/#fiddle/1dm7
I seen a reference on another thread to set position : relative, this does set the text to the center of the bar but doing so means the bar does not show the progress anymore. I see when the progress bar is created it has 2 divs, containing the following classes, x-progress-text and x-progress-bar, both contain the text value.
Thanks in advance
You can extend ProgressBarWidget, and override the template, like:
Ext.define('Fiddle.view.ProgressBarWidget', {
extend: 'Ext.ProgressBarWidget',
xtype: 'fiddle-progressbarwidget',
template: [{
reference: 'backgroundEl'
}, {
reference: 'barEl'
}, {
reference: 'textEl',
style: {
left: 0,
right: 0
}
}],
});
Working example: https://fiddle.sencha.com/#fiddle/1dn4
The definitive solution is to add an onResize handler on the progress bar container:
onResize: function () {
var me = this,
progressBar = me.down('progressbarwidget');
// Set text width to element width so that it can be centered
progressBar.setWidth(progressBar.el.getWidth());
}
This idea is copied from what happens in Ext.grid.column.Widget.onResize().
The solution from user CD.. doesn't work (nor does the one in user2751034 comment)
in the case you have two-color-text, like in Classic theme:
even if you reproduce the template in Sencha sources (with textEl children of barEl):

I'm using heatmap chart (https://apexcharts.com/docs/chart-types/heatmap-chart/) and i would like to hide a single item in legend: the series 1 label called "label1".
The results would be something like:
So, i just want to hide a single item in legend and not the entire series
Easiest way would be to use pure js to hide first legend item after chart renders, like this
document.querySelectorAll("#chart .apexcharts-legend-series")[0].style.display = "none";
Second solution to hide first series using options
legend: {
formatter: (seriesName, opts)=>{
if(opts.seriesIndex==0) return '' // hides first label
return seriesName;
},
markers: {
width: [0,12,12,12], // hides first marker
}
}
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'm trying my hands on extjs 4 by trying to recreate some component I have in an old extjs 2 project.
One of the component was creating a floating toolbox (like you get with photoshop) with a thin border and no title or min/max/close buttons. Like so..
In ext4 , I can't seem to be able to reproduce that same result. Here's what the same code looks like in ext 4:
This is the code I had:
app.Toolbox = Ext.extend(Ext.Window, {
,initComponent : function()
{
Ext.apply(this,{
closable:false,
border:false,
width:345,
height:60,
onEsc:Ext.emptyFn,
resizable:false,
x:20,
y:20,
items:[
/* icons (a html items) */
]
});
app.Toolbox.superclass.initComponent.call(this, arguments);
}
/* handlers, methods, etc */
});
Is there any way to get a similar result in ext 4?
I tried using some css to hide some elements like the title bar, but ext 4 always calculates the height of the window as if the element was visible, which looks even weirder.
Any idea?
Ext.panel.Header is just an extended Ext.container.Container so you can do as you wish to it.
I think the closest you're going to get is by applying frame: true which kind of forces the content to fill the window frame.
However, it doesn't seem to work if you have a Close button in the top right.
Ext.create('Ext.window.Window', {
height: 60,
width: 345,
closable: false,
layout: 'fit',
frame: true,
items: {
html: '<p>hello</p>'
}
}).show();
You're still going to have to style it a little, but its far closer to what you need.
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 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).
