Ext.field.Select by default comes with the buttons: "Done" and "Cancel", but I need to add a third button in the middle, an "Add" button, that allows the user to insert a new option if what he needs is not in the options.
Is there a way to do this in Sencha Touch?
Thanks
Yes, it is possible. First of all, see these two documentation pages toolbar, defaultPhonePickerConfig to learn how to add custom buttons to picker toolbar.
As an example:
{
"xtype": "selectfield",
// also there is defaultTablePickerConfig
"defaultPhonePickerConfig": {
"toolbar": [
{
xtype: 'button',
text: 'Add',
align: 'left',
handler: function(){}
}
]
}
}

I am trying to create a universal titlebar with a back button for my application. I am including it in the various views by using {xclass:mUserStories.view.titlebar}.
Here is the code for the titlebar:
Ext.define('mUserStories.view.titlebar', {
extend: 'Ext.TitleBar',
id: 'narwhal',
config: {
docked: 'top',
// id: 'narwhal',
title: 'CHW Module',
items: [{
ui: 'back',
text: 'Back',
id: 'backButton'
// hidden: true
}]
}
})
However, when I try to dynamically change the toolbar when switching to different pages, the console.log of the titlebar says the _title has changed but the text on the titlebar and the "hidden" property of the button does not change.
Here is the code for the logic that occurs when the button is pressed to switch the page:
toPage: function (arg) {
var t = Ext.getCmp('narwhal');
var b = Ext.getCmp('backButton');
console.log(t,b)
if (arg === PAGES.PATIENT_LIST) {
t.setTitle('Patient List');
b.setHidden(true)
}
Ext.getCmp('viewPort').setActiveItem(arg);
}
I have also tried to include a ref at the top for Narwhal : '#narwhal' and use var t = this.getNarwhal(), but this does not work either.
I am not sure if the problem lies with where the id is being kept, how the id is being called, or because the page is not refreshing properly. Any advice would help!
Thank you for your time :)
I have had the same situation in my project.
I managed to get everything to work like you want it by having a controller owning a reference to the title bar and listening to activeItemChange on my tabPanel.
How to add interactive, dynamic components on a fixed location outside of all views in a Sencha Touch application.
With the menu at the top, I would like to add controls to the bottom of the app that control audio, display other random information and rotate imagery. This pane should not hide/move/refresh/etc. when changing views via the menu, in essence it should be separated from the rest of the application. It is highly preferred to be able to use the sencha 'audio' xtypes.
Should I implement this:
Straight into index.html
Somehow add it in the view which holds the menu as well
Some other magical way
The magical way is... Docking ( outside the rest of the app, probably means you want to doc on the viewport ).
http://docs.sencha.com/touch/2-0/#!/api/Ext.Component-cfg-docked
var button = Ext.create('Ext.Button', {
text: 'Button',
id: 'rightButton'
});
Ext.create('Ext.Container', {
fullscreen: true,
items: [
{
docked: 'top',
xtype: 'titlebar',
items: [
button
]
}
]
});
Ext.create('Ext.Panel', {
html: 'Floating Panel',
left: 0,
padding: 10
}).showBy(button);
For your top view, I would use something along the lines of a Ext.TabPanel though.
http://docs.sencha.com/touch/2-0/#!/api/Ext.tab.Panel
I have a panel with a titlebar which already have a two buttons, one on the left and another on the right of the bar. Now I would like to know how to add a panel (or else) to the center of the bar.
This panel need to have a picture and se string inside.
This is what I do for the moment but the panel is displayed on the right of the left button and I can't figure out how to put it in the middle of the titlebar.
this.getTitlebar().add([{
xtype: 'panel',
layout:'hbox',
items:[{
xtype:'img',
width:32,
height:32,
src:data.image.small.url
},{
html: data.key,
style:'color:#FFF'
}]
}]);
[UPDATE] : centered: true
I tried to add centered: true to my panel config but it didn't work, it actually got worse
from this
to this
Thanks
don not need to add the "spacer"
items: [
// your_first_button(default:left)
{},
// your_central_panel
{centered: true},
// your_second_button
{right: 0}
]
Hope this helps.
To align your items as described, simply use this prototype:
items: [
{your_first_button},
{xtype: 'spacer'},
{your_central_panel},
{xtpye: 'spacer'},
{your_second_button},
]
Hope this helps.
If you're trying to achieve the same thing, don't use a Ext.Titlebar but use a Ext.Toolbar instead.
Things like {xtype:'spacer'} don't work in Titlebars...
Did you try insert method of the component?
You can have something like this
yourComponent.insert(index,componentTobeAdded);
And after adding it, call the component layout of the Toolbar to show the panel added.
How can I set icon used in my Panel's "Title Bar"? Maybe I need to add an image myself, but if so I suppose I need to define or configure that somewhere?
{
xtype: 'treepanel',
title: 'Projects',
width: 200,
store: Ext.data.StoreManager.lookup('projects'),
tools: [
{
type: 'add', // this doesn't appear to work, probably I need to use a valid class
tooltip: 'Add project',
handler: function() {
console.log('TODO: Add project');
}
},
...
]
},
There are a set of 25 icons that can be specified by using the type config.
check http://docs.sencha.com/ext-js/4-0/#!/api/Ext.panel.Tool-cfg-type
To get add symbol use
tools:[{
type:'plus',
tooltip: 'Add project',
// hidden:true,
handler: function(event, toolEl, panel){
// Add logic
}
}]
the specified type:'add' is not in the list
If you want to add your own tool type and be able to assign it an image of your own, you can do the following:
Add a css class in your css file:
.x-tool-mytool { background-image: url(path_to_your_image_file) !important; }
Then in your tools, simply use 'mytool' as the type:
{
type:'mytool',
tooltip: 'This is my tool',
handler: function(event, toolEl, panel){
// my tool logic
}
}
Make sure that you use the same name in tool's type as you used for the css class suffix.
according to the ExtJS documentation, these predefined types are available:
collapse, expand, maximize, minimize, resize, restore, move, close
minus, plus, prev, next, pin, unpin, search, toggle, refresh
save, print, gear, help
right, left, up, down
one can enter whatever type one wants:
{type: 'YOURTYPE'}
while providing a 15px icon - or preferably icon sprites
(the background-position certainly not applies for single icons, but icon sprites):
.x-tool-img.x-tool-YOURTYPE{
background: url('../images/custom_tool_sprites.png') no-repeat 0 0;
}
sources: Ext.panel.Tool-cfg-type, codefx.biz.
I think you mean "set buttons used in my Panel's Title Bar", not "set icon". You can use buttons config of Panel, not tools:
buttons: [{
text: 'Add',
tooltip: 'Add project',
handler: function() {
console.log('TODO: Add project');
}
}]
You can use other configurations like bbar (bottom bar), fbar (footer), tbar (top), lbar (left), rbar (right) for position the toolbar. One small notice is the config objects in buttons have the default xtype as button, so you don't need to explicitly specify them.
I'm trying to implement a list filter in a text field in sencha touch. For example, I'd have a bunch of contacts, and when I typed in the field, it might filter by name. When I click the circular X button to clear the textfield, I'd like to reset the filter to filter none of the contacts.
The problem is, I can't seem to figure out a way to detect the click on the clear button. There doesn't appear to be any type of event, and I can't seem to hack in a workaround.
If anyone has any idea how to detect a textfield clearing in sencha touch, I'd be much obliged.
I've tried in safari and xcode simulator, and am using sencha touch 1.1.0. Am I missing something? Is this not an issue when it's actually a mobile app?
You can listen for tap events on clearIconContainerEl inside the text field or override the onClearIconTap method.
Ext.setup({
icon: 'icon.png',
tabletStartupScreen: 'tablet_startup.png',
phoneStartupScreen: 'phone_startup.png',
glossOnIcon: false,
onReady: function() {
var searchField = new Ext.form.Search({
name : 'search',
placeHolder: 'Search',
useClearIcon: true,
onClearIconTap: function() {
if (!this.disabled) {
this.setValue('');
console.log('onClearTap: Clear button tapped!');
}
}
});
var viewport = new Ext.Panel({
fullscreen: true,
dockedItems: [{
xtype: 'toolbar',
dock: 'top',
items: [searchField]
}]
});
console.log(searchField.useClearIcon);
searchField.mon(searchField.clearIconContainerEl, {
scope: searchField,
tap: function() {
if (!this.disabled) {
console.log('clearIconContainerEl: Clear button tapped!');
}
}
});
}
});
For sencha touch 2.0 users:
If your using new mvc structure, you can use this in the controller init
this.control({
'#yourTextFieldId clearicon': {
tap: function(){console.log('ClearICON tapped');}
}
....
)};
The problem is the little X is not added in by sencha touch. It is a feature of the "search" input with html5. To capture this event you need to look for the search event. How I solved this was I edited sencha-touch.js
I modified -
if (this.fieldEl) {
this.mon(this.fieldEl, {
focus: this.onFocus,
blur: this.onBlur,
keyup: this.onKeyUp,
paste: this.updateClearIconVisibility,
mousedown: this.onBeforeFocus,
scope: this
});
to be -
if (this.fieldEl) {
this.mon(this.fieldEl, {
focus: this.onFocus,
blur: this.onBlur,
keyup: this.onKeyUp,
paste: this.updateClearIconVisibility,
mousedown: this.onBeforeFocus,
search: this.onSearch,
scope: this
});
inside of Ext.form.Text = Ext.extend(Ext.form.Field, { ...
Now in my implementation of the searchfield I can make a function called onSearch which will be called when the "search" event is called. Note that the "search" event is not only called for the X but for some things like the enter key. The bottom line is sencha touch 1.1 does not check for this event at all and it is the only time the X fires an event so the only solution is to modify sencha-touch.js.
