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.

I've been looking at adding a simple calendar to an ExtJS app and like the features of the tui-calendar.
I've started with just trying to display a month in a panel. I've tried various layouts, length and width configs, but the calendar never fully displays. Here's a fiddle showing the results.
Any ideas what I'm missing?
Thanks in advance,
Gordon
You can use layout: 'fit' on the panel and set the div's width and height to 100% with html style, like <div id="calendar" style="width:100%;height:100%"></div>. This way you:
tell the panel (which has a fixed size) that it will have one child that should occupy all available area,
tell the div which contains the calendar to use 100% of the available place horizontally and vertically.
Ext.create('Ext.panel.Panel', {
renderTo: document.body,
height: 600,
width: 600,
layout: 'fit',
tbar: [{
xtype: 'button',
text: 'Display Calendar',
handler: function (button) {
const container = document.getElementById('calendar');
calendar = new tui.Calendar(container, options);
calendar.setDate('2023-03-01');
}
}],
items: [{
html: '<div id="calendar" style="width:100%;height:100%"></div>',
xtype: 'component'
}]
});
I'd like to note that I am not sure that this way ExtJS will manage the life cycle of the calendar object. I would recommend to keep track of the created calendar object and destroy it when the panel is destroyed. To do so, add a destroy listener event to the panel and destroy the calendar object there.
Are there any color picker for extjs (such as photo shop color picker) that developed only on extjs (not in jQuery).
I’m using (Ext.ux.ColorPicker) ux.colorpicker but, it can’t fill my requirement.
Thanks,
Thanuja.
ExtJS has a simple colorpicker.
xtype: 'colorpicker'
From the help:
Ext.create('Ext.picker.Color', {
value: '993300', // initial selected color
renderTo: Ext.getBody(),
listeners: {
select: function(picker, selColor) {
alert(selColor);
}
}
});
You can also look at this one which is more Photoshop-esque and works with Ext JS 4x+, but does require canvas support.
I realize this is an old question. but nevertheless for people looking to have these two libraries play nice... here is what I did. The problem lay in that jscolor expects all the inputs with class "color" to be available on window.load, which is called via jscolor.install(). Of course, ExtJs elements are not available at that time. Try this:
Ext.create("Ext.form.field.Text",{
renderTo: Ext.getBody(),
fieldCls:"color",
name:"TestPost",
listeners: {
afterrender: {
delay:200,
fn:function(item){
jscolor.init();
}
}
}
});
Running jscolor.init() will start it all up. If you like, you can comment out the jscolor.install() call at the bottom of the jscolor.js file, so long as you call jscolor.init() as a listener that runs after the rendering of the textfield you want to be your color picker.
I've been unable to add Scroll Bars to two views I have displaying with Ext. Each View is an extension of a base view, and the base has autoScroll: true. I've verified that the elements are properly assigned an overflow: auto property.
I've done some searching around and found this question and after applying it's solution (even though I wasn't using this 'vbox' layout) it didn't solve my problem.
Here is the base view:
Ext.define('Our.extensions.baseList', {
extend: 'Ext.view.View',
itemSelector: 'div.postContainer',
autoScroll: true,
initComponent: function(){
this.tpl = new Ext.XTemplate(
'<tpl for=".">',
'<div name="postContainer" class="postContainer">',
// Contains Layout for posts
'</div>',
{ // can run internal functions within a template
createButton: function(idPost){
// Creates layout for buttons and returns it
}
}
);
this.callParent(arguments);
}
});
And the two child views are:
Ext.define('Our.view.post.convList', {
extend: 'Our.extensions.baseList',
alias : 'widget.convList',
emptyText: 'No Conversation Followed',
title: 'Coversations',
initComponent: function(){
this.store = new Ext.create('Ext.data.Store', {
id:'convStore',
model: 'Our.model.Post',
data: []
});
this.callParent(arguments);
}
});
And:
Ext.define('Our.view.post.postList', {
extend: 'Our.extensions.baseList',
alias : 'widget.postList',
emptyText: 'No Posts',
title: 'Posts'
});
Ultimately, my question is does Ext.view.View actually support the autoScroll config property (or does it just ignore it as it seems to), which is listed in the Sencha docs as a valid config property. I know that it doesn't support the layout config hence why the linked questions solution failed to work. If it does support it, how would I go about getting the scroll bars to show up?
EDIT
Some things I've discovered in my attempts to come up with a solution, setting a size on the View itself works as long as the size is hard coded (a set number of pixels). Such as adding the config: height: 500, or a CSS class with height: 500px; but percentage sizes through CSS classes don't work at all - they don't even size the component.
SECOND EDIT
As I stated in comments to the first answer received, the component was getting the size 1063 (a note is that, the development environment is on a 1080x1920 monitor (in portrait) and with the JavaScript Console running in Chrome it's the height of the visible frame is 1063 pixels. By 'visible' I mean the postPanel that the Views are being added to.
I have found a temporary solution, unfortunately I don't think it's ideal for an actual production release - I'm using the refresh of the XTemplate to set the height of the component to the height of the panel to that of the postPanel (which sets the same height as it has been receiving) and this seems to force it to apply the scroll bars. I also added a listener to the resize event of the postPanel that fires the refresh event of the two Views.
The additions...
to the child views:
listeners: {
refresh: function() {
var parent = this.up('postPanel');
if (parent != undefined) {
this.setSize({
width: undefined,
height: parent.getHeight()
});
}
}
}
and to the postPanel:
listeners: {
resize: function() {
var postList = this.down('postList');
if (postList != undefined) {
try {
postList.fireEvent('refresh');
} catch(e) { /* ignored */ }
}
var convList = this.down('convList');
if (convList != undefined) {
try {
convList.fireEvent('refresh');
} catch(e) { /* ignored */ }
}
}
}
The main reason I feel this is not an ideal solution is that it's broken the views automatic resizing to half the width of the parent (and setting the width to parent.getWidth() / 2 in the this.setSize() call in the refresh event doesn't alter the size at all, even if the parent is resized. In addition to that, I'm not sure if this will add any overhead to slower computers or not.
So the autoScroll should work as long as the component knows the size of the box it is supposed to fit in. If you don't want to set a specific box size try placing your view component into a viewport with fit layout. Then the viewport will dictate the size of the box and your view should start scrolling in the allocated space. This principal is used for all containers - some one somwhere must specify the size of the box. Viewport is the magic component that figures out the size of the full screen by default.
Try to place each of your views in a container with layout: 'fix'. Then the autoScroll: true of the views will force the scroll bars, when the content requires it.
i was trying to drag and drop an image inside a panel of extjs. but it didnt work.
Just want to drag and drop elements like in the draggable demos of jquery. Is there an easy solution cause i didn't found.
thanks in advance,
cheers,
Thomas
I am sorry ChrisR, forgot the code. Well i tried it in that way:
panel(with html code of an image) inside a panel. dreagable = true. But i cant drag an drop it like to position XY.
Ext.createWidget('panel', {
renderTo: 'panel1',
width: 500,
height: 500,
items: [
{
xtype: 'panel',
title: 'My Panel',
width: 150,
height: 150,
draggable: true,
html: '<img id="resizeImg" src="avus_gtr.jpg" style="width: 100%; height: 100%;"></img>'
}]
You realize you are adding an image into a panel which is draggable and insert that panel again into your main panel? It isn't the image you are making draggable, it's the panel that the image sits in which is draggable but still the code you posted looks totally wrong.
I suggest you read up on ExtJS DD first to grasp the concepts of Drag and Drop in ExtJS and how that is implemented in default Components like Panels. The way of using DD on an Ext Panel is totally different than making an image draggable. A Panel is an Ext Component with alot of built in features like DD but an image is just a DOM element on which you should implement your DD behaviour yourself.
Check the following links, they have some good info on DD in ExtJS

I have a combobox inside of a ext.panel, inside of an ext.window. When I click the down arrow to show the possible SELECT options, the options pop up at the top-left of the browser window, instead of below the SELECT box. The funny thing is if I attach the drugDetailsPanel (see code below) to a div on the page (instead of inside an ext.window), the combobox works correctly. This also happens when I change ext.panel to ext.form.formpanel, by the way.
Any ideas?
My code:
drugDetailsPanel = new Ext.Panel({
layout:'form',
id:'drug-details-panel',
region:'center',
title:'Drug Details',
height:200,
collapsed:false,
collapsible:false,
items:[
new Ext.form.ComboBox({
fieldLabel:'What is the status of this drug?',
typeAhead:false,
store:drugStatusStore,
displayField:'lookup',
mode:'remote',
triggerAction:'all',
editable:false,
allowBlank:false,
emptyText:'Select a status..',
name:'/drug/drug-status',
id:'drug-status'
})
]
});
newDrugWindow = new Ext.Window({
title: 'Add Drug',
closable:true,
width:650,
height:650,
//border:false,
plain:true,
layout: 'border',
items: [drugDetailsPanel],
closeAction:'hide',
modal:true,
buttons: [
{
text:'Close',
disabled:false,
handler: function(){
newDrugWindow.hide();
}
},
{
text:'Save Drug',
handler: function(){
newDrugDialog.hide();
}
}]
});
Try to add shim: true to combo-box control.
Older versions of Ext had issues like this in certain browsers (FF 2.x) in certain situations dealing with nested positioning, the specifics of which escape me now. If that's the case, search the Ext forums for more info. If not, then I'm not sure...
This forum thread helped me: http://www.sencha.com/forum/showthread.php?177677-IE-displays-combobox-dropdown-in-the-top-left-corner-of-browser-window
Just give the combobox a (unique) name. Giving the combobox an inputId should also help
Seems like IE does not respect the position of the element if it does not have an explicit name/inputId. This thread goes more deeply into it: http://www.sencha.com/forum/showthread.php?154412-Combo-Box-options-appears-in-Top-Left-Corner-in-IE-9
