How to use custom sass in Ext JS 7

I have been trying to change the button colour in a form I have created on Ext JS v7.0.0.40
Login.js location is app\modern\src\view\main\Login.js
extend: "Ext.form.Panel",
xtype: "form-login",
title: "Login Form",
bodyPadding: 20,
width: 320,
autoSize: true,
items: [
{
xtype: "textfield",
allowBlank: false,
required: true,
label: "User ID",
name: "user",
placeholder: "user id"
},
{
xtype: "passwordfield",
allowBlank: false,
required: true,
label: "Password",
name: "pass",
placeholder: "password"
},
{
xtype: "checkbox",
boxLabel: "Remember me",
name: "remember"
}
],
buttons: [
{
text: "Login",
handler: "onLogin"
}
]
});
Login.sass location is app\modern\sass\var\view\main\Login.sass
.form-login {
.button {
background-color: #ff3737;
}
}
For some reason I cannot get the color of the button to be changed, I'm sure this has a pretty simple fix.
Thanks in advance!

Welcome to Stack Overflow:
You did not set the cls (custom class for the element) for the form.
And the button styling for the background-color is done in a subelement:
scss file:
.form-login {
.x-button .x-inner-el {
background-color: #ff3737;
}
}
https://fiddle.sencha.com/#view/editor&fiddle/325q
Further information:
To find out yourself, you can inspect the button and see that,
the button cls is x-button
adding the background color to the x-button will not help
going further down inside the x-button is the x-button-el and adding the background color there will acutally change the color.
The scss file should go parallel to the form-login file, but you do not have to do that.
If you plan to use this type of color
more often: Use a cls and create a custom component with that style
always: Take a look at the documentation to change the button background color in your theme

EXTJS: How can I add an click event on Icon node in a Tree Panel

I try to get an event click on the node's Icon in a tree panel.
I have a tree with many node and in front of the leaf node, I have an Icon.
For the moment, when I click on a node I display a PDF file.
I want to do a specific action when I click on the Icon of this node.
Someone have an idea for do that?
Thanks a lot for your futur answers!
EDIT:
Thanks for your answer,
#Hown_: Ok, but I must do an specific action which depends to the select node. With a CSS selector, I can't do that. I'm wrong?
#budgw: Yes, it's a good solution, but my icon must be in front of the text node :(

I guess the simplest way would be to add itemclick event to your TreePanel and check in the handler fn if the tree icon was clicked by checking the target of the event. It works as simple as this:
You may have to change the css selector of the getTarget fn for your specific use. ( e.g. only leaf elements or pdf icons or something like that )
Ext.onReady(function() {
var store = Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [{
text: "detention",
leaf: true
}, {
text: "homework",
expanded: true,
children: [{
text: "book report",
leaf: true
}, {
text: "alegrbra",
leaf: true
}]
}, {
text: "buy lottery tickets",
leaf: true
}]
}
});
Ext.create('Ext.tree.Panel', {
title: 'Simple Tree',
width: 200,
store: store,
rootVisible: false,
renderTo: Ext.getBody(),
listeners: {
itemclick: function(treeModel, record, item, index, e, eOpts){
var iconElClicked = e.getTarget('.x-tree-icon');
if(iconElClicked){
//tree icon clicked
//do something in here
console.log('tree icon clicked');
}
}
}
});
});

I don't think you can do that with the icon in front of the node (maybe I'm wrong).
But I usually solve this kind of use case by using a treepanel with 2 columns :
a treecolumn
an action column like in this example here.
The trick is to use the config property 'hideHeaders:true' on the tree panel to make it looks like a classic tree.

You can select the dom elements of the icons via css selector and add a click event after the render method.
here is an example:
https://fiddle.sencha.com/#fiddle/8kd
UPDATE:
exmaple:
Ext.onReady(function() {
var store = Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [{
text: "detention",
leaf: true
}, {
text: "homework",
expanded: true,
children: [{
text: "book report",
leaf: true
}, {
text: "alegrbra",
leaf: true
}]
}, {
text: "buy lottery tickets",
leaf: true
}]
}
});
Ext.define('MyPanel', {
extend: 'Ext.tree.Panel',
title: 'Simple Tree',
width: 200,
onTreeIconClick: function(treeModel, record, item, index, e, eOpts){
// DO SOMETHING IN HERE
console.log('onTreeIconClicked');
},
render: function(){
this.callParent(arguments);
var domEls = this.el.dom.querySelectorAll('#' + this.getId() + ' .x-tree-icon', this.el.dom);
for(var i = 0; i<domEls.length; i++){
Ext.get(domEls[i]).on('click', function(){
//click on tree icon
this.on('itemclick', this.onTreeIconClick, this, { single: true });
}, this);
}
}
});
Ext.create('MyPanel', {
store: store,
rootVisible: false,
renderTo: Ext.getBody()
});
});

ExtJS4 - Change font size of TabPanel title text

I need to change the text of the title of the tab in a TabPanel, but I don't want that this will affect every other TabPanel in the application, just this TabPanel.
I tried adding a CSS class by the cls property, by the itemCls property, and by this:
defaults: {
cls: 'aClass'
}
The CSS:
.aClass {
font-size: smaller;
}
But they all look the same:
Nothing seemed to work. How am I able to achieve that?

You should indeed use the cls property on your tabpanel and then have a custom CSS selector that would only point to that tabpanel:
See here: http://jsfiddle.net/49Dc8/
JS
Ext.require('Ext.tab.*');
Ext.onReady(function(){
// basic tabs 1, built from existing content
var tabs = Ext.createWidget('tabpanel', {
renderTo: 'tabs1',
cls: 'mytab',
width: 450,
plain: true,
activeTab: 0,
defaults :{
bodyPadding: 10
},
items: [{
contentEl:'script',
title: 'Short Text'
},{
contentEl:'markup',
title: 'Long Text'
}]
});
});
CSS
.mytab .x-tab-inner{
font-size: 13px;
}

Sencha static top and bottom bars for page changes

I've been learning sencha touch 2.0 over the last 2 weeks and i've stumbled onto two problems. What i would like to do is have a static top bar and bottom bar on my page and let the dynamic content be controlled by buttons placed at the bottom dock. I've spent 4 hours on trying to get this to work the way i want to, i'm almost there but i need a little guidance.
My first problem is that i want to add an image to the static top dock. The code that was suggested in another form does not work.
var topBar = new Ext.BoxComponent(
{
xtype: 'box',
autoEl: {tag: 'img', src:'/resources/icons/icon.png'}
}
)
This code doesnt give any errors but it also doesnt show the required image. The image is 60px by 30px
The second problem i'm having is that i would like to add icons to my bottom dock so that when the user click on them, the page would change to show a new page. I have a form with 3 fields that i would like to link to one of the icons on the bottom dock so when the icon is clicked, the form would show. Here is the full code:
Ext.setup({
phoneStartupScreen : 'resources/images/icon.png',
icon : 'resources/images/Homescreen.png',
glossOnIcon : false,
onReady : function() {
var topBar = new Ext.BoxComponent(
{
xtype: 'box',
autoEl: {tag: 'img', src:'/resources/icons/icon.png'}
}
)
var tapHandler = function (btn, evt) {
alert("Button '" + btn.text + "' tapped.");
}
var form = new Ext.form.FormPanel({
items:
[
{
xtype: "textfield",
name: "name",
label: "Name",
placeHolder: "your name here"
},
{
xtype: "emailfield",
name: "email",
label: "Email",
placeHolder: "you#example.com"
},
{
xtype: "urlfield",
name: "url",
label: "Url",
placeHolder: "http://www.example.com"
}
]
})
var searchPageContent ={
html:'This is a test for search page'
}
var userPageContent ={
html:'This is a test for user page'
}
var dockedItems = [
{
xtype : 'toolbar',
dock : 'top',
items : topBar
},
{
xtype: "toolbar",
dock: "bottom",
items: [
{
xtype: 'spacer'
},
{
iconMask: true,
iconCls: "favorites",
items: form
},
{
xtype: 'spacer'
},
{
iconMask: true,
iconCls: "search",
items: searchPageContent
},
{
xtype: 'spacer'
},
{
iconMask: true,
iconCls: "user",
items: userPageContent
},
{
xtype: 'spacer'
},
]
}
]
new Ext.Panel({
id : 'buttonsPanel',
fullscreen : true,
dockedItems : dockedItems
});
}
});
as mentioned before, i have been able to create the static top and bottom bars but my image does not work in my top bar, which is my first problem, and when i click one of the 3 buttons, nothing happens; i would like my form to be displayed when i click my favorites button but nothing happens. Where have i gone wrong?
Thank you

After a few days of wrestling with sencha, i found an example that almost had what i wanted so modified it and it worked out exactly the way i wanted. I now have a static top bar and a static bottom bar with page icons such that when i click the page icons, the main content scrolls and the new page is displayed.
Ext.setup({
onReady: function() {
var topBar = new Ext.BoxComponent({
layout: 'hbox',
html:
'<img src="resources/icons/icon.png" height="30", width="48"/>',
flex: 1,
style:{
textAlign: 'center'
}
})
var dockedItems = [
{
//this creates the top bar, places it at the top of the page and gives it a background image
xtype : 'toolbar',
dock : 'top',
style: 'background-image:url("resources/images/backgroundSmall.png"); background-repeat: repeat-x;',
items : topBar
}
]
// Sub-page sections
// Main portion of the page, which includes top toolbar and content
var welcome = new Ext.Panel({
items: [{
html: 'this is the welcome screen'
}],
title: "Welcome",
iconCls: "welcome",
});
var search = new Ext.Panel({
items: [{
html: 'this is the search screen'
}],
title: "Search",
iconCls: "search",
});
// This is the outer panel with the bottom toolbar
var wrapper = new Ext.TabPanel({
fullscreen: true,
tabBar: {
dock: 'bottom',
style: 'background:#8a9cB2;',
layout: {
pack: 'center'
}
},
items: [
welcome,
search,
{
iconMask: true,
iconCls: "search"
},
{
iconMask: true,
iconCls: "user"
}
],
dockedItems: dockedItems
});
}
});

Ext js FormPanel is not showing panel items when toolbar is present

I seem to be having a weird issue here. An extended component has the following code:
MyApp.panels.RelationshipDetails = Ext.extend(Ext.FormPanel, {
closable: true,
relationshipId: null,
documentId: null,
title: 'Relationship',
initComponent: function () {
if (!this.verifyRequiredData()) {
MyApp.panels.RelationshipDetails.superclass.initComponent.call(this);
return;
}
// Build components
this.tbar = this.buildToolbar();
this.items = this.buildDetailItemArray();
MyApp.panels.RelationshipDetails.superclass.initComponent.call(this);
},
verifyRequiredData: function () {
// Verification code here
},
buildDetailItemArray: function () {
return [{
xtype: 'fieldset',
title: 'Details',
collapsible: true,
autoHeight: true,
items: [{
xtype: 'hidden',
name: 'Id'
}, {
xtype: 'textfield',
fieldLabel: 'Name',
name: 'Name'
}, {
xtype: 'textfield',
fieldLabel: 'Description',
name: 'Description'
}, {
xtype: 'button',
text: 'Save',
name: 'saveButton'
}]
}];
},
buildToolbar: function () {
return new Ext.Toolbar({
// Toolbar Config
});
}
});
The issue is that when this panel renders, the toolbar is the only thing that renders. Through debugging I can see that BuildDetailItemArray() is being called correctly and returning the correct result.
It gets even weirder when I comment out the this.tbar = line, because when the toolbar is not present, the fieldset and field renders correctly. This occurs even if I extend Panel instead of FormPanel. I also tried abstracting out the form fields into it's own component, and the same thing occurs.
Anyone have any idea why this doesn't seem to work?

What sort of layout are you trying to put this panel into? Also, are you setting a height for this panel?
Often, if you aren't specifying a height for the component to be added (in your case, this panel), or you're not setting an anchor if using an AnchorLayout, component content won't be shown, but the toolbar still will.
It'd be good to know the context of this panel in your overall layout.
