Whenever I add a form to a card layout, all the form items seem to disappear. I tested my layout here:
http://tof2k.com/ext/formbuilder/
with this code and got the same result, (use show/edit JSON to try it or build one yourself)
How can I make the for fields visible?
{
xtype:"panel",
title:"Panel",
items:[{
layout:"card",
title:"CardLayout Container",
activeItem:"0",
items:[{
xtype:"form",
title:"Form",
items:[{
xtype:"textfield",
fieldLabel:"Text",
name:"textvalue"
},{
xtype:"textfield",
fieldLabel:"Text",
name:"textvalue"
}]
}]
}]
}
I figured out the answer, ensure you set the height property of the form or else it will be hidden.

I've been looking at adding a simple calendar to an ExtJS app and like the features of the tui-calendar.
I've started with just trying to display a month in a panel. I've tried various layouts, length and width configs, but the calendar never fully displays. Here's a fiddle showing the results.
Any ideas what I'm missing?
Thanks in advance,
Gordon
You can use layout: 'fit' on the panel and set the div's width and height to 100% with html style, like <div id="calendar" style="width:100%;height:100%"></div>. This way you:
tell the panel (which has a fixed size) that it will have one child that should occupy all available area,
tell the div which contains the calendar to use 100% of the available place horizontally and vertically.
Ext.create('Ext.panel.Panel', {
renderTo: document.body,
height: 600,
width: 600,
layout: 'fit',
tbar: [{
xtype: 'button',
text: 'Display Calendar',
handler: function (button) {
const container = document.getElementById('calendar');
calendar = new tui.Calendar(container, options);
calendar.setDate('2023-03-01');
}
}],
items: [{
html: '<div id="calendar" style="width:100%;height:100%"></div>',
xtype: 'component'
}]
});
I'd like to note that I am not sure that this way ExtJS will manage the life cycle of the calendar object. I would recommend to keep track of the created calendar object and destroy it when the panel is destroyed. To do so, add a destroy listener event to the panel and destroy the calendar object there.
I need to customize the yes no combo within a specific panel, local to the panel without affecting the parent yesnocombo box configuration. Is there a way to do this?
I am referring to the form I posted earlier in another thread in the Sencha forums, but no one has answered. The url is:
http://www.sencha.com/forum/showthre...ng-Sencha-form
I tried this:
var myNewStore =[
"", "Yes", "Revoke"];
Ext.define('YesNoCombo',{
extend:'Ext.form.ComboBox',
store:myNewStore,
value:'',
emptyText:'Select...',
labelalign:'left',
labelWidth:550,
inputWidth:80,
allowBlank:true,
listeners:{
select:function(comp,record,index){
if(comp.getVelue() == "" || comp.getVale() ===" ")
comp.setValue(null);
}
}
});
but this broke the format of the form.
Is there a way to create a local combo with custom variables like this:
var UserForm_BlahBlahBlah=Ext.create('YesNoCombo', {
name:"UserForm_BlahBlahBlah",
fieldLabel:"BlahBlahBlah",
values:" Yes" "Revoke",
});
I tried this but it will not work. But you get the idea- It is just creating a local extension within a specific panel with new values.
Is this possible? Or is there a better way that sencha implements customizing the combo box with out affecting the parent class?

You can easily extend Ext.form.ComboBox class and create your own combo box class. Then you can use your combobox in forms.
In the exmaple I create custom combobox by using its xtype which I defined by alias: 'widget.yesNoCombo'. You can also create instance of custom combobox by var combo = Ext.create('YesNoCombo');
Ext.define('YesNoCombo',{
alias: 'widget.yesNoCombo',
extend:'Ext.form.ComboBox',
store: ["No", "Yes", "Revoke"],
emptyText:'Select...',
allowBlank:true
});
Ext.create('Ext.form.Panel', {
renderTo: Ext.getBody(),
items:[
{
xtype: 'yesNoCombo',
fieldLabel:'Yes No Label',
name: 'combo',
},
{
xtype: 'textfield',
fieldLabel: 'Another field',
name: 'anotherField',
},
]
});

I cannot change the tabbar titles in a tab Panel.
Edit: I'm working on a test app witch consists in a main tab panel with other three views, similar to the "getting started video" of the sencha-touch documentation.
Now, for localization purposes, I need to change dinamically the labels under the icons of the tab bar, representing the three links to the panels.
In the code below there is my attempt to change the label of the first button by changing the title of the related view, as the label display "Home", that is the title of the view.
I want to do that on the "activate" event of the view.
The result of this code is that if I log the title of the home view, it is changed but the tab bar button label remains the same.
I think that I miss something like "refreshing" the button, but I cannot find anything on this subject on the documentation.
I hope this edit explains better my question.
Here is the code:
Ext.define('lvzMobile.view.Main', {
extend: 'Ext.tab.Panel',
requires: ['Ext.TitleBar'],
xtype: 'main',
config: {
tabBarPosition: "bottom",
items: [
{
xtype: 'homePanel',
id: 'home',
},
{
xtype: 'catalogue',
id: 'catalogue'
},
{
xtype: 'infoPanel',
id: 'info'
}
],
listeners: {
activate: function() {
console.log("activate");
this.getAt(0).setTitle("emoh");
//the title changes but nothing happens in the tabbar...
}
}
}
});
Please, can you help me? I can't understand what's wrong.
The line that says:
this.getAt(0).setTitle('emoh')
…will change the title of your panel, but not the button itself. To change the button text, use:
this.getTabBar().getAt(0).setTitle('emoh')
Here's a fiddle with your code to demonstrate.
While there, here's a tip: use alias: 'widget.main' instead of xtype: 'main'. xtype is for configs, alias is for defining the alias which in turn can be used later with xtype (use prefix widget. to be used as a widget, store. to be used as a store, etc.).
I have a combobox inside of a ext.panel, inside of an ext.window. When I click the down arrow to show the possible SELECT options, the options pop up at the top-left of the browser window, instead of below the SELECT box. The funny thing is if I attach the drugDetailsPanel (see code below) to a div on the page (instead of inside an ext.window), the combobox works correctly. This also happens when I change ext.panel to ext.form.formpanel, by the way.
Any ideas?
My code:
drugDetailsPanel = new Ext.Panel({
layout:'form',
id:'drug-details-panel',
region:'center',
title:'Drug Details',
height:200,
collapsed:false,
collapsible:false,
items:[
new Ext.form.ComboBox({
fieldLabel:'What is the status of this drug?',
typeAhead:false,
store:drugStatusStore,
displayField:'lookup',
mode:'remote',
triggerAction:'all',
editable:false,
allowBlank:false,
emptyText:'Select a status..',
name:'/drug/drug-status',
id:'drug-status'
})
]
});
newDrugWindow = new Ext.Window({
title: 'Add Drug',
closable:true,
width:650,
height:650,
//border:false,
plain:true,
layout: 'border',
items: [drugDetailsPanel],
closeAction:'hide',
modal:true,
buttons: [
{
text:'Close',
disabled:false,
handler: function(){
newDrugWindow.hide();
}
},
{
text:'Save Drug',
handler: function(){
newDrugDialog.hide();
}
}]
});
Try to add shim: true to combo-box control.
Older versions of Ext had issues like this in certain browsers (FF 2.x) in certain situations dealing with nested positioning, the specifics of which escape me now. If that's the case, search the Ext forums for more info. If not, then I'm not sure...
This forum thread helped me: http://www.sencha.com/forum/showthread.php?177677-IE-displays-combobox-dropdown-in-the-top-left-corner-of-browser-window
Just give the combobox a (unique) name. Giving the combobox an inputId should also help
Seems like IE does not respect the position of the element if it does not have an explicit name/inputId. This thread goes more deeply into it: http://www.sencha.com/forum/showthread.php?154412-Combo-Box-options-appears-in-Top-Left-Corner-in-IE-9
Inside my FormPanel , I have a fieldset with a layout of 'column'.
I have tried several different config properties but i cannot get the label for my textfield to work. It just renders the textbox without a label.
(Obviously, if i make the layout type 'form', i have no issues). The text for the checkboxes shows fine, but the textbox label does not. Can someone point out what is wrong ?
thanks!
xtype:'fieldset',
title:'Transaction Status',
layout: 'column',
style:'margin:5px;'
,height:125//or:'-20', allowBlank:false}
,defaultType: 'checkbox'
,defaults: {
columnWidth: '.32',
border: false
},
items: [{
id:'check1-field',
name: 'check1',
boxLabel: 'DOT'
},{
id:'check2-field',
boxLabel: 'Results Matched',
name: 'check2'
},{
xtype:'textfield',
name: 'testname',
fieldLabel:'This doesnt show'
}
]
Ext Docs for TextField
"This config is only used when this Component is rendered by a Container which has been configured to use the FormLayout layout manager."
So, since you have a layout of "column", I don't think it will render.
Best best is probably to place your check boxes in a separate field set below the text entry boxes, or just remove the column layout style and change it to form (the default).
I had the same problem with you..
I solved it using panel xtype.
set your checkboxes becomes the items of a panel.
