I'm working on an app that, from the Main.mxml, opens one or many Window.mxml instances. When it's done I want all windows to be chromeless so the custom controls need to work.
In Main I've added applicationComplete="init();" so the init function gets ran, which contains clickhandlers, which makes the buttons work.
However, this way of running an init function doesn't seem to be valid for an mx:Window.
I can cheat by not using a clickhandler for the minimize and close buttons with a click="this.minimize();", but I don't know of a way like this to make the move work because it's a MOUSE_DOWN event.
Question 1:
Is there a way to have such an init function in an mx:Window?
Question 2:
What's a good way to make the buttons on the Window instances all work?
ps. If you think question 2 needs a separate post please let me know, they're so closely related and seemingly simple I couldn't decide.
Example code:
Main.mxml - http://pastebin.com/0HHVpkb8
Window.mxml - http://pastebin.com/g5TWuLYk
Window doesn't have an applicationComplete event, but it does have windowComplete event. Perhaps that would work for you. There is a list if Window events here.

Researching https://fullcalendar.io/docs/vertical-resource-view for work
It seems the columnHeaderHtml callback does not work for this view.
https://github.com/fullcalendar/fullcalendar-scheduler/issues/429
Is this still the case? Any way around this?
I also need the ability to click a timeslot. Eg. clicking the 10 AM row to create an event at 10 AM. Does this functionality exist? I can't seem to find any callbacks that seem to work.
My codepen so far:
https://codepen.io/anon/pen/OKyvGZ?editors=0010
EDIT: #ADyson pointed out that columnHeaderHtml only works for date headers, not resource headers as is the case here.
DukeScript is quite clever in the way it handle changes to the Model so that code is hot-swapped at runtime, see for example here.
One thing it doesn't seem to handle at Runtime though is changes to the HTML layout. Given it runs in a WebView, a kind of a browse, it would nice just to be able to reload the page without having to stop and restart the app.
So, I've tried adding a "reload" button, but I can't find an easy way to do that after the initialization:
BrowserBuilder
.newBrowser()
.loadPage("pages/index.html")
.loadClass(Main.class).
invoke("onPageLoad", args).
showAndWait();
showAndWait() does what it's supposed to do, it doesn't return until the browser is closed. There doesn't seem any way to act on the underlying instance of a WebView and its thread.
Ha ha, simple but effective solution:
Reload
Note: Toni Epple says NetBeans would just detect the change, no reload needed.
I have a main application calling several ViewStack states, each with popup windows. If I don't open any popup windows, I can move between states fine. If I open a popup window then try to change the state using currentState=... I get the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I see others having the same problem, for example here:

http://bugs.adobe.com/jira/browse/SDK-32036?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel
But I haven't figured out how to implement the recommended solution. It sounds like I should just include:
import mx.managers.PopUpManager; PopUpManager;
inside my main application and it should work, but it doesn't work for me.
My application has each view state in a different file, each defined using <views:View>. Also, all of the popups are separate files defined as <s:TitleWindow>. Each file includes this line:
import mx.managers.PopUpManager;
I wonder if this means each file is using a different popup manager(?), when it's a singleton and only one should be used for the whole app (how to set that up?).
The code I use to call a popup is:
var _popupName:MyTitleWindowFileName = MyTitleWindowFileName(
PopUpManager.createPopUp(this, MyTitleWindowFileName, true));
_popupName.addEventListener(MyAppController.CLOSE_POPUP,onClosePopUp);
PopUpManager.centerPopUp(_popupName); // call popup
Note that when the main application (the one defined as <s:Application>) runs, the ViewStack states have not been loaded yet (since they get loaded when they are used the first time). Not sure if that has any cause/effect here.
I've tried to follow Adobe's example code in the "Passing data to and from a Spark pop-up window" section here:
http://help.adobe.com/en_US/flex/using/WS6c678f7b363d5da52e8f1ca1124a0430dcf-8000.html#WS6c678f7b363d5da52e8f1ca1124a0430dcf-7ffe
Any ideas much appreciated.
Based on your comments, it seems like the error occurs because the focus remains in the popup. I would expect the PopUpManager and FocusManager classes to handle this better.
One thing I can think of is that the FocusManager may be trying to handle this. But since the state changes, the item that originally had focus (in the view stack child, before the pop up was opened) may no longer be there when the view state changes. Just a hunch, w/out seeing your code.
Here's some things you can do to either work around the problem (or better) further debug it to understand what is happening:
Use FocusManager.setFocus() to move the focus back to an object in the view stack child before closing the pop up
Use FocusManager.getFocus() to debug and see where it thinks the focus is at various stages (before opening popup, before/after changing state, and before/after closing pop up).
It appears this is the situation I'm experiencing:
Adobe Air: scroller throws error when changes focus between different applications
It's an Adobe bug. Solution from Adobe is:
This bug is easily fixed by changing Scroller to do a null pointer check on focusManager before using it.
which is what the first link above attempts to do.

I have a problem.
My app is a tab bar controller and its first view controller is a split view controller.
This seems to be not ok for Apple because documents say a split voew controller must be the root, so perhaps that is the reason of my problems.
The problem is that sometimes, willHideViewController from UISplitViewControllerDelegate is not called, so, for this reason, the upper/left button sometimes is not created, which is anoying.
I realised, to reproduce this error, try several times this:
-Landscape mode.
-Select a tab different to split view controller tap.
-Move the iPad to portrait in that tab.
-Go to the split view controller tab, and sometimes, willHideViewController is not called so you will not see the upper button. However if I rotate my iPad to landscape and after that to portrait, it's fixed.
I tried to force manually several rotations to work around this problem, but no luck.
I still have to try any split view controller clone class from github or similar.
Do you have idea what's going on or any work around?
Here I show you two examples working properly.
Thanks a lot for your help.
Where do you set the splitViewControllers delegate? Perhaps you can set the delegate when you load the tab. It sounds like you set it only when you have rotated once?
Otherwise, see this example
Here they have the TableViewController be the delegate of the splitviewcontroller. Perhaps you could do the same with the TabBarController?
I've concluded that this can't be done in any way that I consider 'sufficiently' legitimate. It's possible to get frustratingly close, but the issue of having the willShow..., willHide disseminated to the split view controllers under each tab remains.
The solution that seems most likely to work is,
https://github.com/grgcombs/IntelligentSplitViewController/blob/master/IntelligentSplitViewController.m
Though this code is undoubtedly clever, it's a bit too 'side door' for me. I suspect (but don't know) that just invoking the delegate methods is not sufficient. Surely the UISplitViewController itself needs to change it's internal state as well as calling the delegate methods? This method 'just' invokes the delegate methods when there's an orientation change.
So... I've decided on a more legitimate solution, which is to use the new method introduced in iOS 5.
- (BOOL) splitViewController:(UISplitViewController *)svc
shouldHideViewController:(UIViewController *)vc
inOrientation:(UIInterfaceOrientation)orientation
{
return NO;
}
So, the master menu is never hidden, and therefore the problem of managing the popover doesn't arise.
Of course, this is still not totally 'legit' as it still includes UISplitViewControllers that are not at the top level (the UITabViewController is at the top level, and the split views are on each tab)
Good luck with whichever solution you choose.
I'll update this reply when I've confirmed Apple will approve an app using this solution.
I've used JRab's example here http://supportforums.blackberry.com/t5/Tablet-OS-SDK-for-Adobe-AIR/App-specific-system-menu/td-p/693... to add a header menu to my app. What I'm having trouble with is executing my functions from the header mennu. For example, my firstView is appHome.mxml. It instantiates a Canvas object that has an erase(). There is a button in appHope.mxml that executes the erase() on the Canvas instance. I'm trying move the Erase button out of my appHome.mxml and into my headerMenu.mxml but don't know how to execute the erase() on the Canvas instance. The first thing I thought to try was click="{appHome.myCanvas.erase()}" but obviously that didn't work.
I asked a similar question yesterday here: Flex executing a function on another view and I accepted the answer before I tried it. The problem is that the headermenu.mxml is not a child of appHome.mxml. They are both children of the main app.mxml. Secondly, the object that has the erase() is in a separate .as class I instantiate in appHome.mxml.
I hope I described my question well enough. Thanks n advance to anyone that can help.
Based on your description, I don't understand how my comment on the previous answer doesn't answer it.
The event from headermenu dispatches up to app; which can call the method on it's child (appHome) like this:
appHome.erase()
