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 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"/>
I am only a month old with extjs and still experimenting. My question is: I have a grid panel and within it the 'tools' config options. I am using this to enable/disable a Ext.grid.feature.Grouping variable. The 2 handler functions have the logic to disable/enable the 2 views by clicking on the 2 'cross' buttons that appear on the right side of the header. The logic is fine. However, I would like to display my set of custom images in place of the 'cross' buttons. Can this be done? If yes, how? Do I need to make some changes in the css code for that?
I have looked into the documentation and also done a good search but nothing seems to answer my question.
Specify a custom type config on your tools:
Ext.create('Ext.grid.Panel', {
...
tools: [
{
type: 'enable-grouping',
handler: function() {
...
}
},
{
type: 'disable-grouping',
handler: function() {
...
}
}
]
});
Then define the following classes in a stylesheet to style your new tools:
.x-tool-enable-grouping {
background-image: url('path/to/tool/image/enable-grouping.png');
}
.x-tool-disable-grouping {
background-image: url('path/to/tool/image/disable-grouping.png');
}
The size of a tool image should be 15 x 15 px
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 :)
How can I set icon used in my Panel's "Title Bar"? Maybe I need to add an image myself, but if so I suppose I need to define or configure that somewhere?
{
xtype: 'treepanel',
title: 'Projects',
width: 200,
store: Ext.data.StoreManager.lookup('projects'),
tools: [
{
type: 'add', // this doesn't appear to work, probably I need to use a valid class
tooltip: 'Add project',
handler: function() {
console.log('TODO: Add project');
}
},
...
]
},
There are a set of 25 icons that can be specified by using the type config.
check http://docs.sencha.com/ext-js/4-0/#!/api/Ext.panel.Tool-cfg-type
To get add symbol use
tools:[{
type:'plus',
tooltip: 'Add project',
// hidden:true,
handler: function(event, toolEl, panel){
// Add logic
}
}]
the specified type:'add' is not in the list
If you want to add your own tool type and be able to assign it an image of your own, you can do the following:
Add a css class in your css file:
.x-tool-mytool { background-image: url(path_to_your_image_file) !important; }
Then in your tools, simply use 'mytool' as the type:
{
type:'mytool',
tooltip: 'This is my tool',
handler: function(event, toolEl, panel){
// my tool logic
}
}
Make sure that you use the same name in tool's type as you used for the css class suffix.
according to the ExtJS documentation, these predefined types are available:
collapse, expand, maximize, minimize, resize, restore, move, close
minus, plus, prev, next, pin, unpin, search, toggle, refresh
save, print, gear, help
right, left, up, down
one can enter whatever type one wants:
{type: 'YOURTYPE'}
while providing a 15px icon - or preferably icon sprites
(the background-position certainly not applies for single icons, but icon sprites):
.x-tool-img.x-tool-YOURTYPE{
background: url('../images/custom_tool_sprites.png') no-repeat 0 0;
}
sources: Ext.panel.Tool-cfg-type, codefx.biz.
I think you mean "set buttons used in my Panel's Title Bar", not "set icon". You can use buttons config of Panel, not tools:
buttons: [{
text: 'Add',
tooltip: 'Add project',
handler: function() {
console.log('TODO: Add project');
}
}]
You can use other configurations like bbar (bottom bar), fbar (footer), tbar (top), lbar (left), rbar (right) for position the toolbar. One small notice is the config objects in buttons have the default xtype as button, so you don't need to explicitly specify them.
var gusersPanel = Ext.create('Ext.grid.Panel', {
flex:1,
columns: [{
header: 'User Login',
dataIndex: 'user_login',
width:150
},{
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.
