EXTJS: hidden element does not show up after setvisible - javascript

Hello I want to show and image that is like an alert sign when a change is done, then I have a footer panel like this one, with the sign:
Ext.define('footerPanel', {
extend: 'Ext.panel.Panel',
cls: 'fastec_background',
height: 24,
autoScroll: false,
border: false,
layout: {
type: 'border'
},
id: 'panel_footerFastec',
initComponent: function () {
var me = this;
Ext.applyIf(me, {
items: [{
margin: '5 5 0 20',
xtype: 'label',
region: 'center',
html: '<a>© 2012 FASTEC GmbH, Paderborn, Germany - </a><a target="_blank" href="http://www.easyoee.de">www.easyOEE.de</a> <a target="_blank" href="http://www.fastec.de">www.fastec.de</a>'
}, {
xtype: 'container',
region: 'east',
layout: 'table',
id: 'cont_footer_icons',
items: [{
xtype: 'image',
id: 'configchangedIcon',
height: 16,
margin: '5 0 5 0',
width: 16,
maxHeight: 20,
dock: 'right',
maxWidth: 20,
scale: 'large',
src: 'files/images/disk_blue.png',
hidden: true
}, {
xtype: 'image',
height: 16,
id: 'errorIcon',
margin: '5 0 5 0',
width: 16,
dock: 'right',
maxHeight: 20,
maxWidth: 20,
scale: 'large',
src: 'files/images/error16.gif',
hidden: true
}]
}]
});
me.callParent(arguments);
}
});
And the idea is that I have a general function which I could call anywhere and show or hide the icon, but unfortunately I call this function and nothing happens:
changeIconVisibility = function(str, value) {
try {
switch(str){
case 'configchangedIcon':
var img = Ext.getCmp('configchangedIcon');
if(value){
img.setVisible(true);
}else{
img.setVisible(false);
}
break;
}
} catch (e) {
Ext.msg.alert(e);
}
}
I tried by directly calling the component and setVisible(true) as well and nothing happens.

get the footerPanel component and use hide/ show method.
like
var myPanel = Ext.getCmp('your_panel');
myPanel.items.items[1].hide() //second item

Flow layout with nested container

In my Ext JS 6 app, I'm trying to create a flow layout with 3 containers, with the middle container having nested items that need to continue with the flow layout. I can get this working if I add the middle container's items directly, but I don't want to do that... I want them to be separate.
Here's an example:
Ext.application({
name: 'Fiddle',
launch: function () {
Ext.create('Ext.panel.Panel', {
height: 300,
width: 300,
scrollable: true,
renderTo: Ext.getBody(),
title: 'Not properly working',
bodyPadding: 10,
layout: {
type: 'column'
},
items: [{
xtype: 'panel',
title: 'start',
width: 100,
height: 50
}, {
xtype: 'container',
defaults: {
xtype: 'panel',
title: '1',
width: 50,
height: 50,
style: 'float: left;'
},
items: [{}, {}, {}, {}, {}, {}]
}, {
xtype: 'panel',
title: 'end',
width: 100,
height: 50
}]
});
Ext.create('Ext.panel.Panel', {
height: 300,
width: 300,
scrollable: true,
renderTo: Ext.getBody(),
bodyPadding: 10,
title: 'This is how it should look',
layout: {
type: 'column'
},
items: [{
xtype: 'panel',
title: 'start',
width: 100,
height: 50
}, {
xtype: 'panel',
title: '1',
width: 50,
height: 50
}, {
xtype: 'panel',
title: '1',
width: 50,
height: 50
}, {
xtype: 'panel',
title: '1',
width: 50,
height: 50
}, {
xtype: 'panel',
title: '1',
width: 50,
height: 50
}, {
xtype: 'panel',
title: '1',
width: 50,
height: 50
}, {
xtype: 'panel',
title: '1',
width: 50,
height: 50
}, {
xtype: 'panel',
title: 'end',
width: 100,
height: 50
}]
});
}
});
So my flow layout should look like this (depicted in the example's 2nd panel):
start 1 1 1 (newline)
1 1 1 end
I got the idea from this thread, but that doesn't have a nested item like in my example. Also tried to use this thread's advice, but still no dice.
I think the issue is with the auto layout for the middle container, as it sets the width to 100% for its child div, but I'm not sure how to fix this... any advice?

How to switch content of a center panel in by check and uncheck checkbox

I have buttons in west region and by clicking on buttons I am getting different charts in center region(using border layout). In last button click, I created a window with checkbox. When I check the box I want to destroy the the chart in center and create a new chart with controllpanel : true. If it is unchecked then it should be controllpanel:false.
My code for regions is
Ext.define('MyApp.view.main.Main', {
requires: ['Mgo.*', 'MyApp.view.main.MainModel', 'Ext.plugin.Viewport'],
extend: 'Ext.container.Container',
ui: 'navigation',
height: '100%',

floating: true,
controller: 'MainController',
items: [{
xtype: 'toolbar',
height: 50,
region: 'north',
split: true, // enable resizing
//margin: '0 5 5 5',
items: [{
xtype: 'image',
width: 160,
src: 'resources/images/newpowered.gif',
style: "height: 30px; left: auto; right: 1066px; top: 20px; margin: 0px;"
}, '->', {
xtype: 'image',
height: 30,
width: 30,
tooltip: 'About',
position: 'right',
margin: '0 4 0 0',
hidden: false,

}, {

xtype: 'panel',

showLegends: true,
showSlider: false,
showDataGrid: true,
chartType: 'line',
controlPanel:false, // this should be true when checkbox is checked
orientation: 'x'
}]
}]});
Handler for Checkbox is
Ext.define('MyApp.view.main.CheckBox', {
extend: 'Ext.form.Panel',
alias: 'widget.checkboxPanel',
height: 300,
width: 400,
layout: 'fit',
bodyPadding: 10,
items: [{
xtype: 'fieldcontainer',
fieldLabel: 'Select Panels',
defaultType: 'checkboxfield',
items: [{
boxLabel: 'Control Panel',
name: 'ctrlPanel',
inputValue: '1',
id: 'checkbox1',
handler: function(field, value) {
debugger;
if (this.checked == true) {
var xyz = Ext.getCmp('abc').items.items;
for (i = 0; i <= xyz.length-1; i++) {
xyz[i].destroy(); // destroying center element. Need to true controllpanel
}
}
}
}]
}],
renderTo: Ext.getBody()});
Any help will apreciated.
To remove elements and replace with new ones:
handler: function(field, checked) {
var centerContainer = Ext.getCmp('abc');
Ext.suspendLayouts();
centerContainer.removeAll();
centerContainer.add([{
xtype: 'mgoPanel', // My own xtype
itemId: 'igp1',
showZoom: false,
showLegends: true,
showSlider: false,
showDataGrid: true,
chartType: 'groupedBoxPlot',
controlPanel: checked,
orientation: 'x'
}, {
xtype: 'mgoPanel',
itemId: 'igp4',
showZoom: false,
showLegends: true,
showSlider: false,
showDataGrid: true,
chartType: 'line',
controlPanel: checked,
orientation: 'x'
}]);
Ext.resumeLayouts(true);
}

how to show the Window when press the show-btn?
this code i m using Sencha Articheh to create. any idea?
With Ext.define() method you define class, but not creating instance of the class. For creating class instance you have to use Ext.create() method.
Also I recommend to move class definition outside click handler to separate file. If you are using standard application structure created by Sencha architect, create file with class definition in view folder.
So in click handler you will have just:
// create instance of MyApp.view.LeftRightWIndow class
win = Ext.create('MyApp.view.LeftRightWIndow');
// display window
win.show();
On the present moment click event just create window object without displaying it. For showing your window after clicking on 'show-btn', you need just to invoke show() method of window object. So try to place win.show() before last line, like this:
...
me.callParent(arguments);
}
});
win.show();
});

extjs 4 portal example

I would like to say that Im struggling with understanding the portal demo in ExtJS 4. Can someone please just provide me a generic example of a container and how to add a portlet item. The docs provided with the download do not have the word portal or portlet when I do the search. When I look at the source of the example there are classes files and extra CSS files too. Are those needed? I have searched all over the web and only seem to find other people asking the same question. Any help or even a link to a demo for extjs 4 would be greatly appreciated. Maybe my googlefoo is lacking?
When I use the demo and start modifying the border layout I run into all sorts of issues. The center region cannot contain a tab panel, I use accordion layouts for my east, west, and north regions. There seems to be an issue with the West region and having an accordion layout because it does not display properly ie. the accordion is like half open and any images inside do not display unless you collapse and then re-open. Would someone be able to provide me with an example that just shows how to make a basic portal without any added functionality? Below is the code I was using that was not working properly but displays and works fine (except for the portal part) when using just a viewport.
Here is some example code
Ext.define('Ext.app.Portal', {

----------- Just for anyone who reads this Portal Layout IS NOT part of the official framework and is a 3rd party extension bundled with the library, which is why it is not in the docs.
It'ss the portal example with tabs in center region

How to make an ExtJS table layout have percentage instead of absolute values for height and width?

Using Ext.Panel and the table layout, I was able to create a layout just the way I want. However, how do I change this code so that I can define the widths and heights proportionally?
e.g. the table should not be 800 pixels but 100% of the screen width, and each box not 200 pixels but 25%.
here is the code:
<script type="text/javascript">
clearExtjsComponent(targetRegion);
var table_wrapper2 = new Ext.Panel({
id: 'table_wrapper2',
baseCls: 'x-plain',
renderTo: Ext.getBody(),
layout:'table',
layoutConfig: {columns:2},
defaults: {
frame:true,
width:200,
height: 200,
style: 'margin: 0 10px 10px 0'
},
items:[{
title:'Shopping Cart',
width: 400,
height: 290,
colspan: 2
},{
title:'Invoice Address',
width: 190,
height: 100
},{
title:'Delivery Address',
width: 200,
height: 100
}
]
})
var table_wrapper = new Ext.Panel({
id:'table_wrapper',
baseCls:'x-plain',
renderTo: Ext.getBody(),
layout:'table',
layoutConfig: {columns:4},
defaults: {
frame:true,
width:200,
height: 200,
style: 'margin: 10px 0 0 10px'
},
items:[{
title:'Orders',
width: 810,
colspan: 4
},{
title:'Customer Information',
width: 400,
height: 400,
colspan: 2
},{
//title:'Shopping Cart',
frame: false,
border: false,
width: 400,
height: 400,
colspan: 2,
items: [ table_wrapper2 ]
}
]
});
replaceComponentContent(targetRegion, table_wrapper);
hideComponent(regionHelp);
</script>
Instead of :
layout:'table',
layoutConfig: {columns:2},
try this :
layout: {
type: 'table',
columns: 3,
tableAttrs: {
style: {
width: '100%',
height: '100%'
}
}
},
Like I said in the reply to your other thread using vbox and hbox layouts might be a little easier for you if you want to do relative positioning. Also, if you want to stretch things to your window, put it in a Viewport, that automatically uses you entire window.
You might want to change the layout a bit (borders, frames), but with vbox and hbox layouts it would be something like this:
new Ext.Viewport({
layout: 'vbox',
layoutConfig: {
align : 'stretch',
pack : 'start'
},
defaults: {
style: 'margin: 10px 0 0 10px'
},
items:[{
title:'Orders',
height: 200
},{
layout: 'hbox',
flex: 1,
layoutConfig: {
align : 'stretch',
pack : 'start'
},
items: [{
title:'Customer Information',
flex: 1
},{
layout: 'vbox',
flex: 1,
layoutConfig: {
align : 'stretch',
pack : 'start'
},
items: [{
title: 'Shopping cart',
height: 200
},{
layout: 'hbox',
flex: 1,
layoutConfig: {
align : 'stretch',
pack : 'start'
},
items: [{
title: 'Invoice address',
flex: 1
},{
title: 'Delivery address',
flex: 1
}]
}]
}]
}
]
});
try this one fiddle example :
https://fiddle.sencha.com/#fiddle/2dm
