Very simple scenario: I want to have a small grid for a good overview. But when clicking in a cell the editor should have a higher width than the actual column.
Example:
https://fiddle.sencha.com/#fiddle/reg&view/editor
I tried to specify the width and I tried to add it in the afterrender. Width is always exactly as wide as the column. Same problem with textareas.
editor: {
xtype: 'textfield',
enableKeyEvents: true,
selectOnFocus: true,
width: 500,
listeners: {
afterrender: function (field) {
field.setWidth(500);
}
}
}
I thought this should be easy but I couldn't find a way to accomplish that. I can specify the height on a textarea but the width isn't considered.
Check below fiddle.
https://fiddle.sencha.com/#fiddle/27bv&view/editor
Here I have done change for setting width of table node in which cell editor is rendered by Ext.get(Ext.get(Ext.query('div.x-grid-editor')[0]).dom.childNodes[0]).setWidth(300).
This approach is having one limitation- for first time width is not getting set as in beforeedit event we do not get instance of editor.If we get this instance we can apply similar logic for setting editor's width.
please check if it could solve your issue or not.Also let me know for any changes.
Note: I have impl. this thing for first column only.
Okay, I figured out a solution which is pretty close to mine.
afterrender: function (field) {
field.bodyEl.setWidth(500);
}
This works for textareas and textfields with Ext version 5. I found out that in my fiddle I also used the wrong Ext version. Seems not to work with Ext 4.

I am new to ExtJs ,In this I have a textareafield binding data from API response.
What I want to do is if the response has any url's in it I would like to show a tool tip kind of thing with copy option when user hover on it.Can anyone help me to get this .
code:
xtype: 'textareafield',
fieldLabel: 'Reponse',
name: 'response',
align: 'stretch',
allowBlank: false,
flex: 1
response.setValue(StringUtils.addHtmlBreaks(record.get('response')));
Thanks..
I have created simple fiddle where I have shown one textarea and binded mouse events and shown tip accordingly in this fiddle.
textarea.on('mouseover',function(evt,field){
//Show tip if url matches
},this);
textarea.on('mouseout',function(){
//just hide tip
},this);
and matched url in textarea by text.match(/\bhttps?:\/\/\S+/gi)
In this fiddle I haven't implemented copy thing because I want to confirm if this behavior fits for you. Please check and reply for same, and in case of any edits in code suggest same.
I want displayfield to span multiple lines, when there is some large content inside. I tried many configurations and css-styling, but to no avail. If there is no quick solution, could you please advise me another component, that I could use instead of displayfield.
assign width and height config explicitly and if it is not enough use maxWidth and maxHeight configs
check out :
http://jsfiddle.net/acteon/p46v3/
{
xtype: 'displayfield',
value: 'line 1 aasdasdasdasdasdasd line 2 ad asd asd asd asd asdasd',
fieldLabel: 'multiLineField',
width : '20%'
}
Oh, I used textarea with readOnly set to true. It works almost as I want.
This answer is for ExtJS 4.2 - not sure about later versions.
The sass definition file at ext/packages/ext-theme-neutral/sass/src/form/field/Display.scss has a height definition, using $form-field-height. If this height is removed, then the field will expand/contract based on the content within.
I have a custom field component based on Ext.form.field.Base. I got the big idea from this post. But what's bothering me with this solution is the fact, that it has a fixed height. What I would like to have instead is that the container grows in height as I add entries to the grid.
I have made an earlier attempt to make such a field but based on a Panel containing the grid and buttons. Putting this panel into a vbox layout and adding rows to the grid perfectly resized the container form panel. What did I miss to implement that the container would resize?
Here is a fiddle where you should easily see what I mean:
http://jsfiddle.net/amx9j/
I finally got it working!
See this fiddle here: http://jsfiddle.net/amx9j/3/
This configuration for the form worked:
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'container',
layout: 'anchor',
items: [{
//custom fields that change their height
}]
And in the custom field you have to use this.updateLayout() everytime you expect the height to change. In addition I had to implement the onResize method:
onResize: function(w, h) {
this.callParent(arguments);
this.grid.setWidth(w - this.getLabelWidth());
}
Important thing is, to NOT set the height of the grid ;-)
Thanks #Peter for taking the time to look into this!
I have set up an EditorGridPanel with ComboBox's and it's working well. The only issue I'm having is that the width of the ComboBox seems to only expand to the width of the grid column, and not the content of the ComboBox itself.
Is there a way around this?
Here's an example of what I mean:
Thanks!
Use the
listWidth : Number
config option
You could calculate the length of the largest content element and then set the listWidth in the 'expand' event of the combo
Cheers!
listWidth does'nt exist in extjs 4.
Add below to combobox config:
matchFieldWidth: false,
listConfig: {
width: 200
},
You can use RowEditor to managed multi forms editor !
see sencha's samples ;)
I'm working on a project where I have a single GridPanel on a page. The panel can display any number of rows and I have the autoHeight property set, which causes the GridPanel to expand to fit the number of rows. I now want a horizontal scrollbar because on some resolutions not all columns get displayed (and I cannot reduce the number of columns).
If I set the autoHeight I have no horizontal scrollbar, if I do not set it and set a fixed height I have a horizontal scrollbar but the GridPanel obviously does not fit the number of rows....
Is there anything I can do to fix this? I can't seem to find a property that would achieve the result I need.
You will find that putting a parent container (Ext.panel.Panel or any container really) around your grid panel to be successful. If you hard code the height, width and layout (to 'fit') on the parent container, the child item (Ext.grid.Panel) will expand to fill the entire space available from it's parent container.
See pages 80 and 81 of Ext JS 4 Web Application Development Cookbook.
You can use the lazy instantiation notation for 'Ext.grid.Panel'. Meaning use 'grid' for your child container (item) xtype property.
Ext.create('Ext.panel.Panel', {
title: 'parent container',
width: 800,
height: 600,
layout: 'fit',
items: {
xtype: 'grid',
title: 'child container',
... define your grid here
},
renderTo: 'grand parent container'
});
My thought would be to set autoScroll: true on the panel.Panel that contained the grid.
This seems like an issue with your layout settings as opposed to the object properties.
Try setting the layout property of the parent container to 'fit'- can you also provide a code excerpt?
As Ergo said, this is more likely a layout problem - the GridPanel is probably higher than the panel containing it, high enough not to need a scrollbar but not fully visible, obviously. Put the GridPanel into a container with a proper layout, i.e. border layout, fit layout or card layout. Getting layout managers right is generally one of the hardest part of ExtJS-Fu.
adding
viewConfig = {
scroll:false,
style:{overflow: 'auto',overflowX: 'hidden'}
}
sometimes causes a bug with displaying 2 scrollbars. To prevent it in my case I added a listener. And then works fine.
this.on('scrollershow',function(scroller,orientation,eOpts){
if (orientation=='vertical'){
scroller.hide();
}
},this);
