I'm using Dojo 1.9 to start learning, and I'm having trouble disabling the resize of the Simple Textarea. I don't really have a particular need to do this, I was just curious about how to and have since been unable.
There is no property listed in the Dijit API, and changing the CSS either with .set("style"), including it inline in the original container (I'm doing it programmatically), or even trying to set resize to none in the original declaration ie:
var textarea = new SimpleTextarea({
rows: 5,
cols: 10,
onFocus: function(){ console.log("textarea focus handler"); },
onBlur: function(){ console.log("textarea blur handler"); },
selectOnClick: true,
style: "resize=none",
value: "This is a sample SimpleTextarea."
}, "textarea");
Any ideas?
If you set style equal to an object with a key value pair of resize : "none" that will do the trick
var textarea = new SimpleTextarea({
style: {resize : "none"}
}, "textarea");
You can do like this:
<input dojotype="dijit.form.SimpleTextarea"
id="yourTxtWidget"
style="resize:none; width: 230px; height: 75px;"
class="myTextField"/>

Inside a tippy-js v6.3.7 tooltip, I have a 1px height div with background-color: #333. The div is randomly appearing blurred on some tooltips and not others. Removing the transform property on data-tippy-root fixes it but positions the tooltip in the upper-left.
Your answer saved me a ton of time, thanks Vael Victus! One more thing: you are missing a pair of {}, it should be:
popperOptions={{ modifiers: [{ name: 'computeStyles', options: { gpuAcceleration: false } }] }}
I discovered the problem resulted from the transform property used to position the tooltip itself. Tippy v6 uses popper v2, which defaults to positioning this way. You can disable it via popper's gpuAcceleration setting. Here's how I fixed it through Tippy.
opts = {
...opts,
popperOptions: {
modifiers: [{
name: 'computeStyles',
options: {
gpuAcceleration: false, // true by default
},
}]
}
}
tp = tippy(elem, opts);
Firefox did not have this rendering problem, and both Chrome 94 and 96 did.
I'm using the Dgrid Selection grid for a grid that uses check boxes for selecting the content. However, only child node of the tree should show the checkbox as the parents are just categories and can't be selected. Previously I used the editor plugin for this, but it created difficulty with clearing selections (specifically, the "clearSelection" method of the grid did nothing). I switched to the selector plugin, so now selecting and deselecting rows works fine, but now I can't seem to figure out a way to hide the check box on some rows and not others.
Original code
var columns = [
editor({
label: " ",
field: "itemSelected",
sortable: false,
width: 33,
canEdit: function(object) {
// only add checkboxes for child objects
return object.type === "child";
}
}, "checkbox"),
tree({
label: "Item",
field: "shortItemId",
width: 150,
shouldExpand: function() {
return 1;
}
}),
{
label: "Grouping Name",
field: "groupingName"
}
];
var itemGrid = new SelectionGrid({
store: itemStore,
style: {
width: '99%',
height: '99%'
},
columns: columns,
sort: [{attribute: "shortItemId", descending: false}]
});
I used the "editOn" parameter of the editor to hide the check box, but the selector plugin only has the "disabled" parameter, which doesn't hide the field at all.
Is there a way I can get the check box hidden using the selector like I did with the editor?
Looking at the dgrid/selector source, it seems that the input is always created and added to the DOM, regardless of whether it has been disabled. Presumably this is to allow it to be flexible enough to enable and disable checkboxes on the fly without the need to constantly re-create DOM nodes. While it is not possible to prevent these nodes from being rendered, it is possible to hide them with CSS, since the cell node is given a class with the format field-{fieldName} (or in this particular case, field-itemSelected):
// JavaScript
var columns = [
selector({
label: " ",
field: "itemSelected",
sortable: false,
width: 33,
// Disable any checkbox that is not of type "child"
disabled: function (item) {
return item.type !== 'child';
}
}),
...
];
/* CSS */
.field-itemSelected input[disabled] {
display: none;
}
I have a treegrid "templatecolumn" that displays an image based on a condition in an XTemplate.
However, I also would like an html formatted tooltip displayed upon mouseover of the image. I've done this with Ext JS 3.x via ext:qtip metatdata attribute in a renderer, but haven't been able to figure out how to do this in Ext JS 4.1 using tpl and haven't found anything in my searching.
Here's what I have to display the image based on a record value:
var myTemplate = new Ext.XTemplate(
'<tpl if="p > 0">',
'<img src="exclamation.gif" height="16" width="16"/>',
'</tpl>'
);
var schedTree = Ext.create('Ext.tree.Panel', {
...
columns:[
{ header:' ', dataIndex:'p', xtype:'templatecolumn', tpl:myTemplate }
]
}
Has anyone done this or have any suggestions? Is there a better way to do this? Thanks
This isn't a method using XTemplate, but this one works for me:
{
text : 'Zdj',
width: 40,
align : 'center',
dataIndex : 'Name',
sortable : false,
resizable: false,
renderer: function (v, m, r) {
if(r.get('leaf')==true) {
m.tdAttr = 'data-qtip="<img src=services/Images.ashx?id='+r.get('id')+' width=60px height=60px>"';
return '<img src="services/Images.ashx?id='+r.get('id')+'" width="25px" height="25px"/>';
}
}
},
In my example I'm showing a bigger image in tooltip, but there is no problem to show HTML formatted tooltip.
You can add conditions to renderer and in my opinion do more that XTemplate can do.
Your small image should go to return line and tooltip content to m.tdAttr.
You can read more about renderer function here: http://docs.sencha.com/ext-js/4-1/#!/api/Ext.grid.column.Column-cfg-renderer
Hope this helps :)
var gusersPanel = Ext.create('Ext.grid.Panel', {
flex:1,
columns: [{
header: 'User Login',
dataIndex: 'user_login',

},{
header: 'User Name',
dataIndex: 'user_nicename',
width:150

Hi I am using above code for the grid Panel in Extjs4.0.2a When I populate data dynamically in the store the scrollbars are not working .
I have also tried using doLayout() for grid Panel but dosent work too .
The grid Panel is in a Window .
Anything that can solve this problem ?
Actually it works for some time but dosen't work all the time .
I've had the same problem. They use custom scrollbar and it's pretty buggy (especialy in chrome). If you are not going to use infinite scroll the possible solution could be to remove custom scrollbar and use native one. To do that just add the following to the grid's config:
var gusersPanel = Ext.create('Ext.grid.Panel', {
scroll : false,
viewConfig : {
style : { overflow: 'auto', overflowX: 'hidden' }
},
// ...
});
I did gusersPanel.determineScrollbars() when i am adding and removing data from store and it is working fine .
The problem with this is the scroll listener is attached to the div element on the afterrender event, but then if the scrollbar is not needed after a layout operation the div element is removed from the dom. Then, when it's needed again it's added back, but only if enough time has passed the garbage collection makes extjs recreate the div node and this time it's added to the dom without attaching the scroll listener again. The following code solves the problem:
Ext.override(Ext.grid.Scroller, {
onAdded: function() {
this.callParent(arguments);
var me = this;
if (me.scrollEl) {
me.mun(me.scrollEl, 'scroll', me.onElScroll, me);
me.mon(me.scrollEl, 'scroll', me.onElScroll, me);
}
}
});
You written code to layout: 'fit'. It did not work autoScroll.
Change the code to some height and remove layout: 'fit' code.
Like this.
var gusersPanel = Ext.create('Ext.grid.Panel', {
flex:1,
columns: [{
...........
}],
autoScroll: true,
//layout:'fit',
height: 130,
selModel: gusersSel,
store: gusersStore
It is help you. Cheers.
I am using Ext.grid.GridPanel in Extjs 4.
Autoscroll is not working in my GridPanel.
How can I resolve this?
Put below config in your parent container of GridPanel.
layout: 'fit'
And remove autoScroll from GridPanel.
scroll: true,
viewConfig: {
style: {
overflow: 'auto',
overflowX: 'hidden'
}
},
Try the above config option. This also will solve your problem.
If the parent container needs to use some other layout other than 'fit', as suggested by previous comments, you could try this: set the height of the grid once the store loads. Moreover, instead of having to calculate the actual height, this may do the trick:
grid.setHeight('100%')
According to documentation, setHeight can accept "A String used to set the CSS height style."
