I would like to have a "welcome text" before the directory tree in my Ext.tree.Panel, so something like that:
I wrote this code, but it doesn't work:
Ext.define('MyProject.view.permissions.Example', {
extend: 'Ext.tree.Panel',
requires: [
'MyProject.view.permissions.ExampleController'
],
controller: 'example',
xtype: 'exampleWindow',
store: 'examplePermissionTree',
rootVisible: false,
rowLines: false,
//headerPosition: 'left',
lines: false,
autoLoad: false,
autoExpand: false,
items :[{
xtype: 'displayfield',
fieldLabel: 'welcome text',
name: 'welcome',
}],
columns: {
items: [ {
xtype: 'treecolumn',
dataIndex: 'text',
flex: 1
}, {
xtype: 'booleancolumn',
flex: 0.3,
dataIndex: 'granted',
trueText: Strings.permissionGranted,
falseText: Strings.permissionNotGranted
}, {
xtype: 'widgetcolumn',
flex: 0.2,
widget: {
xtype: 'button',
handler: 'onGroupClick',
text: Strings.permissionGrant
}
}
]
}
});
My problem is that the text doesn't appear. It appears only the directory tree.
How Could I fix it? Should I use another approach?
1. Use Tools instead of items
Using tools instead of items can solve the problem. An array of Ext.panel.Tool configs/instances to be added to the header tool area. The code should be like
tools :[{
xtype: 'displayfield',
fieldLabel: 'welcome text',
name: 'welcome',
}],
2. Use label in lieu of displayfield
tools :[{
xtype: 'label',
fieldLabel: 'welcome text',
name: 'welcome',
}],
In the record editing window, I need to use the tree selector, for this, the file Ext.ux.TreePicker is included in the app.js file, which is located in the app folder on the same level as the app.js file.
Ext.Loader.setConfig({enabled:true});
Ext.Loader.setPath('Ext.ux', 'app');
Ext.application({
extend: 'Ext.app.Application',
name: 'App',
appFolder: 'app',
requires: ['Ext.ux.TreePicker'],
...
In the record editing window, set the xtype: 'treepicker' field:
Ext.define('App.view.OperationEdit', {
extend: 'Ext.window.Window',
xtype: 'operation-edit',
alias: 'widget.operationedit',
controller: 'operation_controller',
viewModel: {
type: 'operation_model'
},
defaults: {
xtype: 'textfield',
margin: 10,
labelAlign: 'top'
},
closable: true,
items: [{
xtype: 'form',
items: [
{
xtype: 'treepicker',
store: Ext.data.StoreManager.get('StorageStore'),
fieldLabel: "Mesto_hraneniya",
valueField: 'id',
displayField: 'text',
selectChildren: true,
canSelectFolders: true,
name: 'mesto_hraneniya'
},
......
When I open the edit window, I get an error:
TypeError: p is undefined
Example link Fiddle
Why does an error appear? How to display the treepicker field correctly?
thank
The problem in your code, at least in your fiddle is that you defined the "edit form" as fully json, which will be parsed and executed on load time. Since, there is no StorageStore at load time, store parameter of treepicker will be null and that is the reason you get an error. Proper way would be to set form items on object instantiaton as follows, and the working fiddle is here.
Ext.define('App.view.TestEdit', {
extend: 'Ext.window.Window',
xtype: 'test-edit',
alias: 'widget.testedit',
requires: ['App.store.StorageStore'],
controller: 'app_view_testgrid',
defaults: {
xtype: 'textfield',
margin: 10,
labelAlign: 'top'
},
closable: true,
items: [],
initConfig: function(config){
config = config || {};
config.items = [
{
xtype: 'form',
items: [{
xtype: 'combobox',
store: {
type: 'type-store'
},
fieldLabel: 'Type',
displayField: 'name',
valueField: 'id',
name: 'id_type',
reference: 'mycombo',
}, {
xtype: 'textfield',
fieldLabel: 'My field',
name: 'mytextfield'
}, {
xtype: 'treepicker',
store: Ext.data.StoreManager.get("StorageStore"),
fieldLabel: "Mesto_hraneniya",
valueField: 'id',
displayField: 'text',
selectChildren: true,
canSelectFolders: true,
name: 'mesto_hraneniya'
}, {
xtype: 'button',
minWidth: 70,
text: 'Save',
listeners: {
click: 'saveRecord'
}
}]
}
];
this.callParent(arguments);
}
});
I am creating a grid inside one penal. Now I wanted to access this grid and for that I am writing a function.
which is like this.
function getGrid(obj, store){
debugger;
}
Here obj is grid and store is store.
But I don't know where to write. How to get the correct scope.
my Store and Grid code is
initComponent:function(){
var myData = [
['FFPE Slide',2,'eSample'],
['Plasma',2,'eSample'],
['Whole Blood',2,'eSample']
];
// create the data store
var myStor = new Ext.data.ArrayStore({
fields: [
{name: 'Stu'},
{name: 'Sub'},
{name: 'Excl'}
]
});
{
xtype: 'panel',
region:"east",
header:true,
collapsible:true,
autoScroll:true,
width:"30%",
hideBorders:true,
split:true,
items: [{
xtype:'panel',
title:"Panel Header",
items:[],
id:'East_pan',
tbar: this.desToolbar
},{
xtype:'panel',
title:"Result",
items:[{
xtype :'grid',
id: 'COHART_GRID',
selType: 'checkboxmodel',
frame: true,
store: myStor,
autoHeight: true,
stripeRows: true,
columns: [
{
text: 'Study',
id: 'Sd',
header: 'Study',
width: 130,
sortable: false,
hideable: false,
dataIndex: 'Stu'
},
{
text: 'Subject',
width: 130,
header: 'Subject',
id:'Sub',
dataIndex: 'Sub',
hidden:false,
},
{
text: 'Exclude',
width: 130,
id:'Ext',
header: 'Exclude',
dataIndex: 'Excl',
hidden:false
}
]
}]
}]
}
}
Thanks for help !!
You can get the grid using getCmp function & after getting the grid you can call getStore on it to get its store:
var obj=Ext.getCmp('COHART_GRID');
var store=obj.getStore();
1) Dont Use getCmp() use Component query.
2) Change id to itemID in the Grid declaration.
xtype :'grid',
itemId: 'COHART_GRID',
selType: 'checkboxmodel',
frame: true,
store: myStor,
autoHeight: true,
stripeRows: true,
3) store = Ext.ComponentQuery.query('#COHART_GRID')[0].getStore().
4) can you access your grid and Store in the Controller.
I have an app that uses a Tab layout with the same grid panel shared as an xtype widget between each form panel bound to each tab.
My Main tab layout is as follows:
Ext.define('cardioCatalogQT.view.main.Main', {
extend: 'Ext.tab.Panel',
xtype: 'main-view',

'Ext.tip.QuickTipManager',
'Ext.layout.container.Card'
],
style: 'background-color:#dfe8f5;',
width: '100%',
height: 400,
layout: 'vbox',

},

height: 50,
width: 280
},{
title: 'Ad Hoc Sandbox for Cohort Discovery'
}] ,
lbar:[{
text: 'Initiate advanced request',
xtype: 'button',

var url = 'https://url_here';
//cardioCatalogQT.service.UtilityService.http_auth(button);

}
}]
},

The only difference between each of the form panels in the tabs are the item components. Each of these form panels references an xtype of 'searchGrid' and renders it like in the attached image:
The problem is that I have 6-instances of this same grid. This works for the most part, but it is causing some issues related to getting control of the checkboxes in my grid along with some bizarre grid store load behaviors, and honestly, keeping track of components using this anti-pattern is a PITA.
I would like to somehow have a single instance of my searchGrid in a lower vertical panel, while an upper vertical panel has the item components I need to change according to the requirements for each tab. An example of how the item controls vary is
My desired behavior is that when I click on a tab, the upper item components would take me to a different form panel, while the lower panel stay fixed on the search grid.
However, I currently have the searchGrid bound to each tab's form panel, since that is the only way I could get this to work.
The searchGrid grid panel looks like:
Ext.define('cardioCatalogQT.view.grid.Search', {
extend: 'Ext.grid.Panel',
xtype: 'framing-buttons',
store: 'Payload',
itemId: 'searchGrid',
requires: [
'cardioCatalogQT.view.main.MainController'

{text: "Key", flex: 1, sortable: true, dataIndex: 'key'},
{text: "Criteria", flex: 1, sortable: true, dataIndex: 'criteria'},

I messed around with using a Vbox layout to get my desired behavior, but was rather unsuccessful. This does not seem like that uncommon of a use case to have an upper Vbox panel change to different form panels based on a Tab click, while the lower Vbox panel remains fixed. Any insight would be most welcome.
If I understand correctly, this small test of mine should do exactly what you want, using a border layout with regions north and center.
