I have a tab panel and every tab has grid in it, but after loading, data in first tab is missing but it displays fine in 2nd tab , this is working in all the browsers in Extjs 4.2 but it is not working in Extjs 5.0 with IE. ( working fine in chrome ) thee is no errors on console. I am getting crazy with this issue. may be it is a bug in Extjs 5. Thanks in advance.
//main panel class
Ext.define('MyApp.view.MyView', {
extend: 'Ext.tab.Panel',
alias : 'widget.myView',
id : 'myView',
autoScroll : true,
activeTab: 0,
height: 600,
layout: {
type: 'column'
},
requires : [
'MyView.view.FirstTab',
'MyView.view.SecondTab'
],
initComponent : function() {
this.items = [
{
xtype: 'panel',
id: 'fTab',
autoScroll: true,
items: [ { xtype: 'firstTab' }]
},
{
xtype: 'panel',
id: 'sTab',
autoScroll: true,
items: [ { xtype: 'secondTab' } ]
}
];
this.callParent(arguments);
}
});
//controller
var isActivieTabSet = false;
// if store1 has data show the first tab
if(store1Count > 0) {
var tab0 = myView.down('#fTab');
tab0.tab.show();
if (!isActivieTabSet) {
searchSummaryView.setActiveTab(tab0);
isActivieTabSet = true;
}
} else {
myView.down('#fTab').tab.hide();
}
//check if store2 has data
if(store2Count > 0) {
var tab1 = myView.down('#sTab');
tab1.tab.show();
if (!isActivieTabSet) {
myView.setActiveTab(tab1);
isActivieTabSet = true;
}
} else {
myView.down('#sTab').tab.hide();
}
I see these issues with your code:
you should not set a layout on tab panel. Tab panel uses card layout internally, most likely it ignores any passed layout but if you set it it may be confusing for developers
you set ids on components - they are unique in the code you posted but it may not be true for the whole application. The general rule is not to manually set ids - you don't need them.
you overnest - you don't need to wrap 'firstTab' in 'fTab'. We always try to use the most shallow containment chain possible.
hiding tabs is very unusual. I'm not saying that it wouldn't work but if you need to hide a tab then you can use card layout with some simple switching logic. Tab panel is de-facto a card layout with tab "buttons" to switch the active card.
Otherwise the code does not give a clue why it should misbehave. I would suggest a) fix the above and, if it does not help b) prepare a showcase at https://fiddle.sencha.com so that I can run it and find the real culprit.
Thank you!!
1) Right , No need to specify the Layout on tab panel. I took this out
2) Right, it is a good practice to not add the Ids but we are nesting these components and show/hide by using these ids.
3) Right, that was the first thing that came to my mind, take out the wrapper panel from the grid and it works fine and show up the data but with this we have two issues.
a) In the Grid we are using 'pagingtoolbar' and shows at the botton (same in the whole application)
this.dockedItems = [ { xtype: 'pagingtoolbar', store: this.store, displayInfo: true,
dock: 'bottom' } ];
We are using the CARD layout and when we take out the panel this always shows at the botton even though the grid has only 5 records and It looks very weird and we don't want to put this on top (dock: 'top' )
b) Other issue iis sometime Column Header and data are not aligned
{header: 'Number', dataIndex: 'number', flex: 1 }
if i take out the flex:1 then all the columns get too narrow and half of the vertical space on the right is empty.
4) We have this use case that if grid does not have any data then don't show the tab. so we have to manually show/hide the tab.
Let me combine these classes & upload them (but it may time because I have to take out only the necessary objects :( ).
Thanks you again for your help!!
My Grid is inside the panel and this panel is inside the main tabpanel. if i removed the panel over the Gris then it works fine.
//this does not works (does not show data in first tab)
{
xtype: 'panel',
id: 'fTab',
autoScroll: true,
items: [ { xtype: 'firstTab' }]
},
//this works
{
xtype: 'firstTab'
}
I guess this is a bug in Extjs 5.0, same code works in Extjs 4.2 and also in Chrome.
OK, i found the solution, I have to add this on the grid.
bufferedRenderer: false,
In Extjs 5 it is true by default and it is not behaving right in IE when the Grid is inside a Panel with pagination. after this everything works great :) Thanks

I have been trying to change the orientation of the output in DataTables dynamically depending on how many columns are visible.
I am setting a global variable, dynOrient, that I calculate as the user shows/hides columns. I then have tried setting it in the button options:
buttons: [
{
extend: 'pdfHtml5',
footer: true,
text: 'Download PDF',
orientation: dynOrient, //HERE
customize: function(doc) {
...
}
}
]
This seems to keep whatever dynOrient was when the button was created, without changing it from landscape to portrait later as dynOrient changes.
I have also tried putting it in the customize function:
doc.content[1].pageOrientation = dynOrient;
This didn't do anything, just kept the default portrait no matter what dynOrient is.
How can I dynamically change the orientation of the pdfHtml5 output in DataTables?
I actually just figured out a solution (I don't know if it's the proper solution though).
I put the information for the button into a global variable, and every time a column get's shown or hidden, I re-calculate the orientation, set the orientation manually in the button information, and remove/recreate the button.
var buttonInfo = {
extend: 'pdfHtml5',
footer: true,
text: 'Download PDF',
orientation: dynOrient,
customize: function(doc) {
...
}
};
//some code...
$("input[name='showhideswitches']").click(function() {
var col = $(this).data('col');
myTable.column(col).visible($(this).prop("checked"));
dynOrient = getOrientation();
buttonInfo.orientation = dynOrient; //Manually overriding orientation
myTable.button('0').remove();
myTable.button().add(0, buttonInfo); //Re-create
}
Maybe someone can offer a better solution, but until then I'm going to keep this in since it works for now.
I have a Sencha Touch 2.3 application that I am helping develop. One of the features I want to implement is uploading a file that I then do various things with using PHP in the back-end. However, I cannot find a way that works to actually complete the upload (or even show a dialog box to select a file to upload!)
I have a navigation bar that looks like the following:
...
navigationBar: {
docked: 'top',
id: 'mainAdminToolbar',
items: [
{ ...
},
{
align: 'right',
hidden: true,
text: 'Import',
itemId: 'ImportBtn',
}
]
...
In my main controller file, I have the following:
ImportBtn: "adminMain #ImportBtn",
"adminMain #ImportBtn": {
tap: "onImportTap"
},
...
I looked at the a lot of examples (such as this one and this one), but I can get none of them to work. I believe the latter might be for a more updated version of the framework, too, but I cannot update as of right now and have to work with version 2.3
What I want to do is the following:
Have a user click the button
Have a dialog window pop up in which a user can select a file
Have the file auto-upload after being selected
Do various server-side things with the file
How can I achieve this using Sencha Touch 2.3?
Try to use
xtype: 'filefield' and it's 'updatedata' event
To select file you can write something like this
{
xtype: 'filefield',
itemId: 'ImportBtn',
listeners: {
change: function (button, newValue, oldValue, eOpts) {
alert(newValue);
}
}
}
And after selecting the file you can get it with this (It works fine in 2.4)
var file = [your-filefield].getComponent().input.dom.files[0];
Here is more about filefield

I have an OpenLayers 2.12/Sencha 2.4 app. On selecting a feature I wish to change to another view - a FormPanel. This works fine using Ext.View.setActiveItem(viewname).
However, there is an issue with Google Chrome on Android, when I change the view from the FormPanel back to the map view, and only after both the virtual keyboard and an Ext.Msg.alert() call have been invoked in the FormPanel.
I've analysed this with Chrome's debugger. When the I click on one of the form fields in the FormPanel, most of the OpenLayers tiles are removed from the DOM. When I set the active item back to the map view, no new tiles are added to the map div so the app ceases to be useful. The svg that is the vector layer also ceases to function usefully.
One version of the app is here: https://treemapp.se/fiddles/sencha/ol-sencha-4.html - all the code is in the html file.
Can anyone help?
Thanks

I added map.updateSize() to the 'painted' listener, which has mostly solved the problem:
Ext.application({
launch: function() {
container1 = new Ext.Container({
scroll: false,
monitorResize: true,
items: [{
xtype: 'component', //xtype: 'panel' - shows nothing
id: 'map',
width: '100%',
height: '100%',
listeners: {
painted: function(){
console.log( "painted" );
if( !map ) {
init( this.id );
} else {
map.updateSize();
}
}
}
}]
});
});
});
Looks like I might need to add a layer.redraw() or layer.refresh() loop for all the layers, as one or two tiles don't get redrawn after the call to map.updateSize() - they do however get drawn after zooming or moving.

I am new in extjs and I am trying to create a customized alert using Extjs4 but I haven't been successful doing so, the main idea is basically to add the company logo on the left side of the window, and the icon of the type of message and the message text aligned to the right side of the window. I tried different approaches but is not working, I tried to create a new window and adding panels, I tried to customize a regular Ext.Msg.show adding items to its properties but they are never displayed, can anybody give me an idea how to get this done or what approach is the best? I've been 2 days trying but I can't make it work and I am running out of ideas. I am attaching the code I did now, many thanks!!:
Ext.Msg.show({
title:title,
msg: msg,
height: 200,
width: 300,
layout: 'fit',
items: {
xtype: 'panel',
html: '<img src="http://localhost:8080/anylogo/companylogo.gif" />'
},
buttons: Ext.Msg.OK,
icon: Ext.Msg.WARNING
});
It's a matter of style. You can assign a CSS class to the message box via cls config:
Ext.Msg.show({
cls: 'alignright-with-logo'
});
This is a novice question. Hopefully this example can educate myself and others As well as fix my problem.
I have an EXTJS layout that is very similar to the EXTJS complex layout example. A TabPanel is the center piece of this layout. One of the tabs renders a GridPanel that displays some data. I want to click on an Edit icon in the table and open up a separate tab to do the editing.
Here are my issues:
1. If mainTabPnl is defined in view_main.js and the handler in grid.js, how do I add a tab to mainTabPnl? This seems like a scope issue.
2. In the following Firefox line, 't' is undefined. Why?
var t = Ext.getCmp('main-tab-panel');
3. If I try to id my tabs, my whole layout goes haywire. What's happening here?
(see 'center2' tab). I thought that if I could do an Ext.getCmp('center2') I could render something in in from a separate handler.
Thanks for any help on this....
// file: view_main.js
var mainTabPnl = new Ext.TabPanel({
region: 'center',
id: 'main-tab-pnl',
deferredRender: false,
activeTab: 0,
items: [{
contentEl: 'center2',
//id: 'center2', /*!!! screen goes haywire!! why? !!!*/
title: 'Main Panel',
autoScroll: true
}, {
contentEl: 'center1',
title: 'Close Me',
closable: true,
autoScroll: true
}]
})
// file: grid.js
var columns = [{
// Column Headers
//...
},{
header: 'Actions',
id: 'actions',
xtype: 'actioncolumn',
width: 50,
items: [{
icon : '/site_media/icons/application_edit.png',
tooltip: 'Edit Record',
handler: function(grid, rowIndex, colIndex) {
alert("Add-Tab "); // The alert works..
/* but mainTabPnl is not defined */
mainTabPnl.add({
title: 'New Tab',
iconCls: 'tabs',
html: 'Tab Body <br/><br/>',
closable:true
}).show();
}
}];
}];
Collect all your UI initialization code into a single call to Ext.onReady made from a single file. This will ensure that the ExtJS library is fully initialized before you begin building your widgets and that interacting widgets are instantiated in the proper order.
Specific answers:
1: There is no "scoping issue" between multiple JS files pulled into the same page through standard includes. Global symbols defined in each file populate the same window object.
2: 'main-tab-panel' doesn't exist yet at the time of that call. Putting all UI initialization into the same Ext.onReady call will prevent this from happening.
3: You are creating a DOM node with an ID identical to that which you are already using for contentEl.
