I hit what seems to be two bugs. Here is a fiddle which demonstrates these bugs. First of all, if you click on the first panel or any other ones, you will see there appear some new panel with a missing title:
And the second bug, is that it is impossible to see the contents of the panel (one textfield, which I put to every panel). The code is as simple as:
Ext.create("Ext.window.Window", {
width: 300,
height: 400,
layout: "fit",
items:[{
xtype: "panel",
layout: {
type: "accordion"
},
scrollable: true,
listeners: {
beforerender: function () {
var i;
for (i = 0; i < 30; i += 1) {
this.add({
title: i,
items:[{
xtype: "textfield",
value: i
}]
});
}
}
}
}]
}).show();
So, the question is how to fix it all?
The outer window should not have a fit layout as this will interfere with the way the accordion layout works as it uses more or less vertical space depending on the user's actions. Also, the accordion should not have scrollable set to true as it is the parent window that should scroll.
The title you are using for the items in the accordion are seen as integer values in JS and so the 0 is not being interpreted as you would like when used in a title (which expects a string). Explicitly converting i to a string will ensure the 0 shows correctly.
In summary, the following changes will enable your code to work better:
On the outer window: remove the layout:fit and add scrollable:true.
On the accordion: remove the scrollable:true.
On the items in the accordion: ensure the title is consistently converted to a string.
See updated fiddle here.
Ext.create("Ext.window.Window", {
width: 300,
height: 400,
scrollable: true,
items: [{
xtype: "panel",
layout: {
type: "accordion"
},
listeners: {
beforerender: function () {
var i;
for (i = 0; i < 30; i += 1) {
this.add({
title: 'box ' + i,
items: [{
xtype: "textfield",
value: i
}]
});
}
}
}
}]
}).show();

I have treepanel. On some specific condition I want to show image on mouse enter and remove that image on mouseleave in treenode. but when i hover the mouse quickly image get added but not getting removed as itemmouseleave event is not getting fired.
I have prepared jsfiidle to understand my problem in which I am trying to change text of node on mouseenter and mouseleave. on slow motion it is working fine but if hover quickly it shows mouseenter even if we are away from node.
Link to jsfiddle : http://jsfiddle.net/79ZkX/238/
Ext.create("Ext.tree.Panel", {
title: "Car Simple Tree",
width: 400,
height: 600,
store: store,
rootVisible: false,
lines: true, // will show lines to display hierarchy.
useArrows: true, //this is a cool feature - converts the + signs into Windows-7 like arrows. "lines" will not be displayed
renderTo: Ext.getBody(),
listeners: {
itemmouseenter: function(_this, _item) {
var name = _item.get("name");
_item.set("name", "mouseenter");
},
itemmouseleave: function(_this, _item) {
//var name = _item.get('name');
_item.set("name", "leave");
}
},
columns: [
{
xtype: "treecolumn",
dataIndex: "name", // value field which will be displayed on screen
flex: 1
}
]
});
I want to remove the image on mouseleave. Thanks
Added manual workaround for this. On Fast Mouse Hover itemmouseleave event will not get triggered. so i am maintaining array of hovered node and on mouseenter of node, checking if array contain element then set text of that node.
added code to this jsfiddle: http://jsfiddle.net/79ZkX/250/
Ext.create('Ext.tree.Panel', {
title: 'Car Simple Tree',
width: 400,
height: 600,
store: store,
rootVisible: false,
visibleNodes: [],
lines: true, // will show lines to display hierarchy.
useArrows: true, //this is a cool feature - converts the + signs into Windows-7 like arrows. "lines" will not be displayed
renderTo: Ext.getBody(),
listeners : {
itemmouseenter: function(_this, _item) {
for (var i = 0; i < this.visibleNodes.length; i++) {
var node = this.visibleNodes[i];
node.set('name', "leave");
this.visibleNodes.splice(i, 1);
}
var name = _item.get('name');
_item.set('name', "mouseenter");
this.visibleNodes.push(_item);
},
itemmouseleave: function(_this, _item) {
//var name = _item.get('name');
_item.set('name', "leave");
var index = this.visibleNodes.indexOf(_node);
if (index != -1){
this.visibleNodes.splice(index, 1);
}
},
},
columns: [{
xtype: 'treecolumn',
dataIndex: 'name', // value field which will be displayed on screen
flex: 1
}]
});
Here is a Sencha fiddle of my tab panel setup. Buttons are dynamically added to a vbox tabs container that is part of an hbox layout setup. The tabs container's width is determined by the flex property.
I've tried setting every button's width: '100%', but upon looking at the Sencha docs on button.width, I find that width takes an integer value representing pixels. I've tried setting the width in style, but I've only succeeded in making the button's width be the width of the screen.
Help and an explanation of the underlying CSS concepts would be greatly appreciated
You're looking for the stretchmax option.
var locationCameraList=[];
Ext.application({
name : 'Fiddle',
launch : function() {
var buttonArr = [];
for (i = 0; i < locationCameraList.length; ++i) {
var tabName = locationCameraList[i].location,
index = i;
var tab = {
xtype: 'button',
cls: 'tab'+index,
text: tabName,
scale: 'medium'
};
buttonArr.push(tab);
console.log(i)
}
var forms = {
xtype: 'container',
flex: 4,
layout: 'fit',
align: 'stretch',
html: 'zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz'
};
Ext.create('Ext.window.Window', {
title: 'Foo',
layout: 'hbox',
items:[{
xtype: 'container',
items: buttonArr,
flex: 1,
layout: {
type: 'vbox',
align: 'stretchmax'
},
autoScroll: true,
height: 200
}, forms]
}).show();
}
});
I display Panel A first, then display Panel B below it. Panel A uses JSONP to get the data and is shown in the callback function of the store load. So it takes about 1 sec to show.
I aligned a floating panel C to Panel B. The floating panel C is something like this:
Ext.define('MyApp.view.MyWindow', {
extend: 'Ext.window.Window',
height: 334,
width: 540,
layout: {
type: 'border'
},
title: 'Run report',
initComponent: function () {
var me = this;
floatingpanel = Ext.create('Ext.panel.Panel', {
html: "something",
width: 100,
height: 50,
floating: true,
listeners: {
'show': {
fn: function () {
floatingpanel.alignTo(PanelB, "tr-tr", [left, top]);
},
scope: floatingpanel,
//delay: 1000, // to wait for other component to show
single: true
}
}
});
Ext.applyIf(me, {
items: [{
xtype: 'form',
bodyPadding: 10,
region: 'center'
}]
});
me.callParent(arguments);
}
});
Then floatingpanel.show() is called to display the panel. It is not added to Panel B though.
If I don't use delay as shown above, the floating panel C appeared somewhere in Panel A since Panel A is not available yet when the floating panel is about to show. So I put the "delay".
After 1 sec, Panel A is shown as the callback succeeded. Now the floating panel C aligns to Panel B in the right place.
Since the callback function may succeed in 1 sec or 10 sec, the delay time is hard to choose.
Are there other ways to work this out? I tried to use doConstrain to attach the floating panel C to Panel B: floatingpanel.doConstrain(PanelB). But somehow it didn't work.
initComponent: function () {
var me = this;
floatingpanel = Ext.create('Ext.panel.Panel', {
html: "something",
width: 100,
height: 50,
// floating: true,
listeners: {
'show': {
fn: function () {
me.alignTo(PanelB, "tr-tr", [left, top]);
},
scope: floatingpanel,
//delay: 1000, // to wait for other component to show
single: true
}
}
});
Ext.applyIf(me, {
items: [{
xtype: 'form',
bodyPadding: 10,
region: 'center'
}]
});
me.callParent(arguments);
}
please use above code instead of ..
I've got a a Tab panel with a few tabs inside. I'm using the iconCls property in the tabs to give each tab an image along with its title. I'm using the fam fam fam 16x16 icons and the default tab space is cutting the images off at the top/bottom.
I tried messing around with the icon's class by changing the margins but it's not helping. According to the documentation the ext.tab.Tab component has padding and height properties, but setting those is not having an effect on the tab at runtime.
Ext.define('AM.view.Tab.Standard', {
extend: 'Ext.tab.Panel',
alias: 'widget.TabStandard',
region: 'center', // a center region is ALWAYS required for border layout
deferredRender: false,
activeTab: 0, // first tab initially active
initComponent: function() {
this.items = this.buildItems();
this.callParent(arguments);
},
buildItems: function(){
var items =
[
{
padding: 10, // nope :(
title: 'Gantt',
autoScroll: true,
iconCls: 'gantt icon',
},
{
height: 10, // nope :(
title: 'Logs',
autoScroll: true,
iconCls: 'logs icon',
},
{
title: 'Help',
autoScroll: true,
iconCls: 'help icon',
}
];
return items
},
});
Perhaps I'm misunderstanding how those properties work, but the everything on the page looks the same.
EDIT: It appears I'm having the same problem with the "Headings" (the bar with the +/-) when used as an accordion panel.
You can customize tabs in a tab panel by using the tabBar property on tabPanel:
var tabpanel = new Ext.tab.Panel({
plain: true,
region: 'center',
tabBar: {
defaults: {
flex: 1, // if you want them to stretch all the way
height: 20, // set the height
padding: 6 // set the padding
},
dock: 'top'
}
});
I've got a sencha touch app, with a panel that contains 3 image buttons, and the idea is that you can use flick scrolling to scroll them left or right to press the correct one.
The first time (after each load of the app) that you touch or flick these buttons, it doesn't scroll, or it scrolls jerkily. It works ok if you touch it and hold your finger steady for half a second before moving. After that initial time it flicks nicely.
The panel is constructed like so:
var picScroller = { // The picture scroller
flex: 1,
cls: 'items',
scroll: 'horizontal',
layout: 'hbox',
defaults: {
width: 235,
height: 160
},
items: [
{ width: 32 },
{ xtype: 'button', id:"bn1", cls:'myimagebutton', pressedCls:'', handler: myHandler },
{ xtype: 'button', id:"bn2", cls:'myimagebutton', pressedCls:'', handler: myHandler },
{ xtype: 'button', id:"bn3", cls:'myimagebutton', pressedCls:'', handler: myHandler },
{ width: 32 }
]
};
And my CSS is like so:
.myimagebutton {
border:0;
border-radius:0;
margin:10px;
}
Any suggestions? thanks so much
Here's an article that lists a solution to a similar-sounding problem (although this may be specific to being used in conjunction with PhoneGap): http://www.senchatouchbits.com/6/fixing-flickering-of-animations-in-phonegap.html
