I am new to flex and as3 and I need to create a workaround for a button issue. I don't know how to have one button created by one class send a click event to another item created in a different class
Therefore, I'd like to place both of my buttons on top of one another, alpha one of them out and have both buttons receive the same click.
Is this possible? How?
One button's click handler can dispatch another button's click event. See this: http://livedocs.adobe.com/flex/3/html/createevents_3.html

Trying to simplify the UX in a Watch application by getting rid of a redundant button which a user has to tap in order to choose a selected item in WKInterfacePicker and perform a next step. Just want to replace the tap on this button with the tap on a picker.
Cannot find such API in the class specification and the following quote haunts me:
The user interacts with a picker by tapping it, using the crown to scroll through items, and tapping again to select an item.
Everything points to the fact that an item can be selected by tapping on a picker and we can get an access to that action programatically. Has anyone faced this task?
To handle focus to picker did tap event use - pickerDidFocus.
If you want handle each tap now there are only one custom way. You need every time did focus picker programmaticaly call [picker resignFocus]
Put picker into group and set background border image to it if you want to customize focus. Set picker focus style to none.
just add a picker to your WKInterfaceController and create an IBAction to react on the pitch events:
I have a dialog based application. I have one static text control and a button on this, both of which I have made invisible in the beginning. I want to show both the controls on reaching a certain condition. When I click this button, again I want to make both the controls invisible.
However, I am able to show and hide the control and also captured the button click event like this:
ON_BN_CLICKED(IDC_MY_BUTTON, &MyDlg::OnBnClickedMyButton)
and defined OnBnClickedMyButton().
But when I press the button, it is not pressed and the event is also not generated.
Any suggestions?
First check if the IDC_MY_BUTTON exists and is valid.
Remember to add DECLARE_MESSAGE_MAP() at the header file.
Also check at the BEGIN_MESSAGE_MAP(MyClass,MyParentClass) if the class
and the parent class you write are right.
I hope this helps.
I think the IDC_MY_BUTTON maybe is invalid or other control has the same ID.
Well, finally I have come to know that though the button was visible but on clicking it was not taking control, hence I used BringWindowToTop() to draw it on top. Now it is being clicked and OnBnClickedMyButton() is also being called.
But now the issue is that after calling BringWindowToTop() the button is not shown. It is shown only when I take the mouse pointer on it. Not able to understand what is the issue.
I have the navigationcontroller based viewcontroller and I overriding the root view controller navigation bar back button in to my custom segment control with different purpose. This navigation controller is placed one of the separate tab in the uitabbarcontroller. If this is used as the separate tab bar then no problem.
But if i use this navigationcontroller inside the more option in tabbarcontroller i am not able to come back to the more option list because of backbutton is overridden in my navigationcontroller.
My idea is add one back button only if my navigationcontroller is used more option tab otherwise i need to hidden the back button.
Please help me in this issue?
You can check if a view controller is in the 'more' section as follows:
BOOL isOnMoreNavigationController = [tabBarController.moreNavigationController.viewControllers containsObject:myViewController.navigationController];
From a UI consistency perspective it might be better to always show the back button in its standard position and move your custom buttons to some other place.
I have a scenario where...
1.) Have created a div with a dropdown list and ok, cancel button
2.) On document ready - registering div created on step 1 into a jQuery dialog
3.) on a javascript button click - I am opening this dialog box.
4.) Now, the problem is - the jQuery dialogbox which I have created, needs to be used by other button clicks as well on same page. Now, my div's (which is a dialog at runtime using jQuery) ok button click is already engaged with a javascript function (button1 click) and I can not associate other button's click events with it - thus stuck up here and have no clues or hit to resolve this.
Anyone have faced this issue in asp.net, jquery earlier? Can someone provide a guidance?
Why you cant associate another event?
buttons will have different id. Is it?
$('#button1').click(function() {
alert('Handler for button 1 .click() called.');
});
$('#button2').click(function() {
alert('Handler for button 2 .click() called.');
});
Is this not possible in your case.?
Options:
1) disassociate the click handler when the function opens the div, then later in the function of opening the div associate a click handler to the button.
2) create multiple buttons toggle them all hidden, associate the click handler to each button you want. When the div is opened do a check to see which button to toggle to visible.
3) create no buttons but have a function create the button on the fly. When the div is opened, create the button for that div by calling the function and passing in a code telling it which button to open and what to associate to the click handler (this can be stored in an array and all that is passed in is the key).
Depending on the application, I have used all of these methods. The last one can have a twist that allows it to call an ajax server based application to get the button text and functionality (stored in a database), this saves you from having to load an array with button data, and also allows for easier expansion of the application.
I am using a box element to add a transparent overlay to a column of buttons. I want to add a click event to the buttons. However, when you click a button the click event is only triggered on the overlaying box. Is there anyway to pass the event to the underlying button or perhaps a better way to display an overlay without blocking the click event?
If you want a DisplayObject (which nearly all visual things subclass in Flex) to be treated as "transparent" to the mouse (i.e. it won't intercept click events), set that object's mouseEnabled property to false.
e.g.
transparentBox.mouseEnabled = false;
