Does anyone know if it is possible to have multiple icon buttons on a Sencha Touch list item that listen to different events? If so, how can I accomplish this?
For instance, say I have a list of people and there's an icon for email, phone and a map to their location for each person. I want to show 3 small icons and be able to map each icon to do 3 separate actions.
This depends on how you are creating your buttons.
If the buttons are simple HTML using itemTpl, you can just listen to the itemtap event on List and use the event argument to detect which button you pressed. You could do this via a custom attribute or even a className:
myListItemTapListener: function(list, index, target, e) {
var el = Ext.get(e.getTarget());
if (el.hasClass('map')) {
this.navigate(index);
} else if(el.hasClass('email')) {
this.email(index);
} else if(el.hasClass('phone')) {
this.phone(index);
}
}
If your buttons are actual Ext.Button's inside a component List, you can simply add a listener onto each button when you create the component. There is an example of how to do this in the DataView Guide in the Sencha Docs.
Component DataView may help you. You can see this [guide]: http://docs.sencha.com/touch/2-0/#!/guide/dataview-section-4
I have wrote a [demo]: https://github.com/hs3180/Sencha-Touch-Component-DataView
, in app/view/,
Main.js, a dataview component with useComponets true, and set defaultType to 'demo.view.Item'.
Item.js, a DataItem, the visible content of each item is a panel ( in Card.js ). I use datamap to link name in record ( within store ) to userName ( in demo.view.Card ).
Card.js, a Panel for each person. A user name title and 3 buttons.

how do I find out if my custom widget has focus in Dojo?
i have dojo editor i wnat to know if the editor has already focus or not?
you can use the module dijit/focus to find out the focus
FROM DOJO DOCS
Tracking active widgets
At any point in time there is a set of (for lack of a better word)
“active” or “focused” widgets, meaning the currently focused widget
and that widget’s ancestors. “Ancestor” can mean either DOM ancestor
(ex: TextBox –> Form), or a logical parent-child relationship (ex:
TooltipDialog –> DropDownButton).
For example, if focus is on a TextBox inside a TabContainer inside a
TooltipDialog triggered by a DropDownButton, the stack would be
TextBox –> ContentPane –> TabContainer –> TooltipDialog –>
DropDownButton.
The activeStack[] parameter indicates this set of widgets, and an app
can monitor changes to activeStack[] by:
require([ "dijit/focus" ], function(focusUtil){
focusUtil.watch("activeStack", function(name, oldValue, newValue){
console.log("Focused widget + ancestors: ", newValue.join(", "));
});
});
the question in title has a different answer than the one in the descriptions.
there are two ways achieving the question in the title, by using dojo's focusUtil ("dijit/focus"). both ways give you something that you could find the widget using it and the dijit's registry ("dijit/registry").
focusUtil.curNode: gives you the DOM Node that currently has the focus. the function below, you could get the widget reference.
function getWidgetByNode(node){
var result;
while (!result && node){
result = registry.byNode(node);
if (node.parentElement)
node = node.parentElement;
else
node = null;
}
return result;
}
var focusedWidget = getWidgetByNode(focusUtil.curNode)
focusUtil.activeStack: gives you an array of the widgets (parent to child) that has the focus. so the last item in the array is the direct widget which has the focus. index values are widget ids, so you should get the widget by the following code
var focusedWidgetId = focusUtil.activeStack[focusUtil.activeStack.length-1];
var focusedWidget = registry.byId(focusedWidgetId);
now if you want to know if the currently focused widget is some specific one, it depends on what you have in hands from that specific widget:
widget itself: like the return values of above samples. now you have to compare if these are the same thing. you can not compare two widget objects using the == operator. you could compare their ids like this:
myWidget.id == focusedWidget.id
widget's id: this way you just easily get the id of the current node from focusUtil and compare it with the id you have liek this:
myWidgetId == focusedWidgetId
references:
http://dojotoolkit.org/reference-guide/1.9/dijit/focus.html
http://dojotoolkit.org/reference-guide/1.9/dijit/registry.html
require([ "dijit/focus" ], function(focusUtil){
var activeElement = focusUtil.curNode; // returns null if there is no focused element
});
check blow url here you can see some examples
http://dojotoolkit.org/reference-guide/1.8/dijit/focus.html#dijit-focus
a) For dojo 1.6: call dijit.getFocus(). This will return an object containing the currently focused dom node, among other things (selected text, etc.). To get the corresponding widget, simply do:
var activeElement = dijit.getEnclosingWidget(dijit.getFocus().node);
This is the full reference for dijit.getFocus(), from the source code:
// summary:
// Called as getFocus(), this returns an Object showing the current focus
// and selected text.
//
// Called as getFocus(widget), where widget is a (widget representing) a button
// that was just pressed, it returns where focus was before that button
// was pressed. (Pressing the button may have either shifted focus to the button,
// or removed focus altogether.) In this case the selected text is not returned,
// since it can't be accurately determined.
//
// menu: dijit._Widget or {domNode: DomNode} structure
// The button that was just pressed. If focus has disappeared or moved
// to this button, returns the previous focus. In this case the bookmark
// information is already lost, and null is returned.
//
// openedForWindow:
// iframe in which menu was opened
//
// returns:
// A handle to restore focus/selection, to be passed to `dijit.focus`.
b) For dojo 1.7 and up, use dijit/focus:
require([ "dijit/focus" ], function(focusUtil) {
var activeElement = focusUtil.curNode; // returns null if there is no focused element
});
I have a custom menubutton in my tinyMCE editor that uses specific HTML elements elsewhere on the page as the menu items. I use a jQuery selector to get the list of elements and then add one each as a menu item:
c.onRenderMenu.add(function(c,m) {
m.add({ title: 'Pick One:', 'class': 'mceMenuItemTitle' }).setDisabled(1);
$('span[data-menuitem]').each(function() {
var val = $(this).html();
m.add({
title: $(this).attr("data-menuitem"),
onclick: function () { tinyMCE.activeEditor.execCommand('mceInsertContent', false, val) }
});
});
});
My problem is that this only happens once when the button is first clicked and the menu is first rendered. The HTML elements on the current page will change occasionally based on user clicks and some AJAX, so I need this selector code to run each time the menu is rendered to make sure the menu is fully up-to-date. Is that possible?
Failing that, is it possible to dynamically update the control from the end of my AJAX call elsewhere in the page? I'm not sure how to access the menu item and to update it. Something using tinyMCE.activeEditor.controlManager...?
Thanks!
I found a solution to this problem, though I'm not sure it's the best path.
It doesn't look like I can make tinyMCE re-render the menu, so instead I've added some code at the end of my AJAX call: after it has updated the DOM then it manually updates the tinymce drop menu.
The menu object is accessible using:
tinyMCE.activeEditor.controlManager.get('editor_mybutton_menu')
where mybutton is the name of my custom control. My quick-and-dirty solution is to call removeAll() on this menu object (to remove all the current menu items) and then to re-execute my selector code to find the matching elements in the (new) DOM and to add the menu items back based on the new state.
It seems to work just fine, though tweaks & ideas are always welcome!
In my project I need to create some play,pause,stop buttons in one composite.
For that I created one composite and added these buttons there. Also I have added the images
for each button. But after drawing, it does not look good. I mean images on the buttons does not look good.Clients are not satisfied. Now is it possible to add Images to Label and give some Toggle button actions to the label? I know I can add images to the label. But when I click the label,it does not give button effect..
If you want a custom look for your 'buttons' you could use labels with custom images (one for the normal state and one for the "pushed" state. Something like:
final Label stop = new Label(composite, SWT.NONE);
stop.setSize(STOP_IMG.getImageData().width, STOP_IMG.getImageData().height)
stop.setBackgroundImage(STOP_IMG);
stop.addMouseListener(new MouseAdapter()
{
#Override
public void mouseUp(MouseEvent e)
{
stop.setBackgroundImage(STOP_IMG);
}
#Override
public void mouseDown(MouseEvent e)
{
stop.setBackgroundImage(STOP_DOWN_IMG);
// DO ACTION
}
});
For a nice UI you could also add a MouseTrack listener and have different images for the mouse over states.
Disadvantage of this is you are making it less accessible as it will only respond to mouse events. If you go for this approach you should look at creating your own class that extends MouseAdapter, and takes the label, images and action to invoke in a constructor so you don't end up with tonnes of very similar anonymous classes.
I have used toolbars in the past to achieve a nice effect.
This will create a toolbar with an item that behaves like a regular button:
//Toolbar button
ToolBar toolBar = new ToolBar(composite,SWT.FLAT);
ToolItem toolItem = new ToolItem(toolBar,SWT.PUSH);
toolItem.setImage(image);
This will a toolbar with an item that has toggle behaviour:
//Create a toggle effect
ToolBar toggleToolBar = new ToolBar(composite,SWT.FLAT);
ToolItem toggleToolItem = new ToolItem(toggleToolBar,SWT.CHECK);
toggleToolItem.setImage(image);
I'm new with Appcelerator and I encountered an annoying problem regarding layout.
I have to do a menu bar that is very easy to do with plain html (ul>li>a and that's all). The problem is that it seems that all button-related functions are not... customizable. I want buttons to be displayed as plain text, not buttons.
The first thought was to use labels (instead of buttons). But... Is this a right way? I need a menu bar, not a text paragraph! Besides that, the menu is somehow flexible, not like labels.
This is one (of many!) things i tried:
var menu_color = Titanium.UI.createButton({
title:Ti.Locale.getString("menu_color") || "Color",
height:24,
top:10
});
I also added borderWidth:0 (no effect) and backgroundColor:none/transparent with no luck.
Help? :)
I usually use views when I need to create what you described above.
For example:
I use a view with a vertical layout, then add my child views. The child views then have listeners for the click or whatever event.
This allows you to have more control over the formatting. A side effect of this is you will need to create your own "press" ui cue in some cases.
var demo = {win : Ti.UI.currentWindow};
(function(){
//Create the container view
demo.vwMain = Ti.UI.createView({height:100, layout:'vertical', backgroundColor:'yellow'});
demo.win.add(demo.vwMain);
demo.fakebutton1 = Ti.UI.createView({height:40, backgroundColor:'blue',left:25,right:25,borderRadius:5,borderColor:'#000'});
demo.vwMain.add(demo.fakebutton1);
demo.fakebutton2 = Ti.UI.createView({top:5,height:40, backgroundColor:'green',left:25,right:25,borderRadius:5,borderColor:'#000'});
demo.vwMain.add(demo.fakebutton2);
demo.fakebutton1.addEventListener('click', function(e) {
alert('Clicked fake button 1');
});
demo.fakebutton2.addEventListener('click', function(e) {
alert('Clicked fake button 2');
});
})();
create a view with layout property is set to vertical and add label or button which you want.View is like in HTML.Hope you understand.
What i have is a single dijit.Menu that contains the dijit.MenuItem objects with labels 1 - 9. It is connected to a sudoku like grid of 81 'nodes' (because there are so many, i dont bother with individual id's, i simply collect them with dojo.query('their-css-class-name')). This is the code i'm using inside of a widget to instantiate the context menu and its menu items.
var contextMenu = new dijit.Menu({targetNodeIds:dojo.query(".sudokuNode"), leftClickToOpen:true});
for(var i = 1; i <= 9; i++) {
contextMenu.addChild(new dijit.MenuItem({
label:i,
onClick: function(evt) {
//??
}
}));
};
contextMenu.startup();
What i'm trying to do is have the node that is clicked, and subsequently opens a popup/context menu, be filled with the value (1-9) selected from the context menu's MenuItems.
My problem is that i dont know how to "know" which of the 81 nodes was the one to fire the oncontextmenu event, and i dont know how to reference that node inside the 'onClick' method declared in the menu item.
Any help demonstrating how to reference the calling node in that context would be appreciated! If this isn't enough information, let me know what else i can do to explain my problem!
evt.target should get you the node that was actually clicked. Depending on the structure, you may need to do some other navigation from there, or use dijit.getEnclosingWidget().
If the MenuItems allow the events to bubble (I'm not sure; haven't used it myself), you could connect to the onClick() method of the Menu, so you've only got the single event listener in play.
