You can use Ext.getCmp Component id. Take a look at this example:

Clicking on the Canvas creates a Grid that contains the Textbox. Hover over the TextBox, a Button is added in this Grid. How to check the existence of the button in the Grid, not to create a duplicate. I tried
if(!((Grid)sender).Children.Contains(Button))
{
DeleteButton deleteButton = new DeleteButton();
((Grid)sender).Children.Add(deleteButton);
}
But it's not working.
Try this:
var yourButton = ((Grid)sender).Children.OfType<Button>().FirstOrDefault();
This will return the first child of type Button if one exists.
I have created a login page, on click of button, I want to load a new page. how can I achieve that?
I have tried:
Ext.create({
xtype: 'login'
});
If 'login' is of type Window or Panel (so a kind of container), you can call show() method after creation.
first you need to remove login page view, after create new view and render it. for example.
get access to top level element. in most case it's viewport and remove all child elements.
var topLvlElement = Ext.ComponentQuery.query("viewport")[0]
topLvlElement .removeAll()
create new view and add it in top level element
var newView = Ext.create("myapp.view.mainPage",{title:"mainPage"});
topLvlElement .add(newView);
I have panel wiht toolbar with buttons. Panel resizable when it small buttons hide in menu. In menu it show icon and value of overflowText. But on click button i need change overflowText.
expandClick: function (btn) {
var me = this;
btn.blur();
btn.overflowText = btn.overflowText === "expand" ? "reduce" : "expand";
view.fireEvent('expandGraph', view);
}
in browser's console on breckpoint i see right value but there is no change in interface. Why?!
btn.setConfig( name, [value] );
try to use this function to set specific initial configs dinamically.
Sometimes the button din't refresh his state if you modify directly the variable
Try to refresh component layout with doLayout() method after you change overflowText property.
Using Wijmo Open ComponentOne's Dropdown, I tried to place it in a registration form that displays when a button is clicked. This form is inside a jquery modal window.
The problem is that it is not displayed like a wijdropdown inside the form.
I supposed that since is was hidden, then it wasn't part of the DOM and so I added a method in the callback of the function that displayed the modal window; when the modal window finishes displaying, then call the .wijdropdown() on the element. However, it didn't work.
In conclusion: the select tag is not being wijdropdowned...
¿Any recommendations?
Script
$(function() {
// show overlay
$('#product-slideshow-overlay-trigger').live('click', function() {
var $registerOverlay = $('#product-slideshow-overlay');
//left position
var positionLeft = ($(window).width() - $registerOverlay.width())/2;
$registerOverlay.css({'left':positionLeft});
//show mask
$('#mask').fadeIn();
$registerOverlay.slideDown(function()
{
console.log("Started");
/**Add WijmoDropdown***/
$('#estado').wijdropdown(function()
{
console.log("Did the wijdropdown");
});
console.log("Ended");
});
return false
});
}); // end document ready function
Refresh the wijdropdown when the dropdown is not hidden:
$('.wijmo_drp').wijdropdown("refresh");
or
Find the wijmo component and check if it's visible or not (styled or not).
And trigger the visiblity changed event when you display the modal window.
if($('.wijmo-wijobserver-visibility').is(':visible'))
{
$('.wijmo-wijobserver-visibility').trigger("wijmovisibilitychanged");
}
I have an MVC app which has a Tab Panel rendered as the only item in the viewport. Within the tabs I would like to put the same type of component, for which the event handling is equal within all tabs.
Therefore I need an ExtJS MVC Controller ref to the active tab, that would lead me to execute events on the components in the active tab. Is it possible to have such a ref?
My current approach is this:
get reference to Tab Panel
call getActiveTab()
call the controller events for the component in active tab
Is it possible to encapsulate the above 3 steps in one controller ref? Would be beautiful :-)
I'm using ExtJS 4.1.
Personally, I think controller refs are overrated. This sounds like a simple case where you can use one as you describe, but I prefer to listen to the event, and navigate from the firing component to the one I need.
In your case, assuming your tab panel contains regular ext panels, I'd do something like the following:
onButtonClick: function (button) {
var panel = button.up('panel[tab]');
if (panel) {
panel.someMethod();
}
}
The up method will find the closest ancestor that is of xtype panel and has a property named tab. If you have more specific xtypes or known properties, use those instead.
The panel should be the active one (else how was its button clicked?) but you can check that by going up another level to the tab panel and getting the activeTab there.
onButtonClick: function (button) {
var panel = button.up('panel[tab]'),
tabPanel = button.up('tabpanel'),
activeTab = tabPanel && tabPanel.getActiveTab();
if (panel && panel === activeTab) {
panel.someMethod();
}
}
Say your tabPanel has itemId: 'content'. Inside that panel you will have bunch of tabs and on each tab you will have bunch of buttons (as an example). And you want to handle all these button's click in one controller. Do I understand you correctly?
I believe that simple ref inside your controller would work:
this.control('#content button', {
click: this.buttonClicked
}
});
