Flex :: Mobile - Navigator.pushView Slow?
Oct 27, 2011
This is a general question on optimization technique and am more than willing to rewrite a majority of my code as I am moving a lot of it to a library.My concern applies not so much to flex performance as I have used methods that have reduced cpu/memory footprint so performance is quick when inside a view.The problem I have is with the navigator.pushView which seems slow, I do call my init function on creationComplete for the view but I have it factored so my init looks like:
private function init() : void {
doStuff1();
doStuff2();

I have a project for mobile where some of my animations scenes look as though they are winding up or playing in slow motion (from the start). They start out slow for about three seconds, as if they are winding up or in slow motion, and then they run at a normal pace. It only happens on specific animations and is consistent on different devices. Also, once I come back to the scene (revisit), the animations run normally from start to finish.
I have had some success in speeding up some animation by doing the following: In some scenes, the following would occurr: 1) a character was walking 2) the character grew in size though tweening 3) the background was animated as well ect. In other words, there were several things happening in the animation. In this example, I made it less complex by keeping the character the same size and making the background static. This helped alot. However, for the aforemation animations, I have tried everything (I am aware of) and nothing has helped. I'm not sure what to do next.

I would like to move (right or left according the current view) between 2 views when I move my finger on the mobile screen; for example with Google+ mobile application, in profil section, you can change the view just on move your finger on the screen, and the offset and the moving speed must be checked before change complete view.

I'm trying to create a custom tab navigator that has to look like. Also, when there's a rollover, the borders of the arrow have to be in blue (like the label in the current tab). For that purpose, I've created a custom component: a hbox containing a label and a canvas with 3 images inside (for the arrow tip that has to change depending on the currentState). Then, I thought of overlapping the components in order to get the blue highlight color (ex: arrow button 3 is over arrow button 4. The image of the arrow tip in button 3 will be transparent outside the arrow, so that we can see the black color of the following button).
I'm now trying to position the components inside the canvas ... but I cannot. After the creationComplete event, I assign the label text and I was calculating the coordonates of the component but it doesn't take into account the label width... -_-'

Suppose I have two tabs in my app:
<ViewNavigator id="tab1" firstView="Tab1">
<ViewNavigator id="tab2" firstView="Tab2">
I go into Tab1, and start pushing other views onto the stack
navigator.pushView(Tab1View1)
navigator.pushView(Tab1View2)
and so on....
Now I want to jump directly, with NO TRANSITIONS, from one of the views deep in Tab1, into one of the views in Tab2. How do I do this?

My problem: I have a tab navigator, with many forms in each tab. But I have a single global save button.Problem is, if I don't open a Tab, it doesn't get initialized and therefore the forms it contains do not exist..
How Can I make it as if the user had clicked on every tab?

I I have a view in Flex 3 where I use a tab navigator and a number of views inside the tab navigator. I need to be know which view was clicked because of it's one specific view then I need to take action, i.e. if view with id "secondTab" is clicked then do something.
I have set it up to be notified, my problem is that I need to be able to know what view it is. Calling tab.GetChildByName or a similar method seems to only get me back a TabSkin object.

I have a flex application mxml file with 3 tabs.the first tab having the link button to select the value in the 3rd tab. Suppose, i have a link button in first atab. And the 3rd tab contains the combobox with values:"basic", "advanced". by default the vaule is displaying "default". When i select the linkbutton on the first tab, the "advanced"should be displayed in the comboBox on the 3rd tab. and the problem is , when click on the first tab link button , at that time the 3rd tab is not initialized. So it is not displaying the "advanced" in the comboBox. selecting the 2nd time on the link button it is displaying fine. But not first time. code: thirdTab.comboBoxId.selectedItem.data = 1;

I have a tab navigator defined in MXML, with two tabs.In each tab, I have some buttons. I have used ActionScript to add event listeners to all the buttons, and they work for the buttons that are visible (and in the currently "active" tab) when I load my Flex 4.5 AIR application.However, I get an AIR error for the event listeners attached to the buttons in the second tab.Here's the crucial part of the error:TypeError: Error #1009: Cannot access a property or method of a null object reference.

does anyone know how to disable that slide animation and just have the action bar instantly change to whatever action bar the next view contains, but still do a slide navigation for the rest of the view. My Action bar doesn't change on every page so seeing the same image reload repetitively in the action bar.

Does anyone know if there is a way to make the new Package Explorer window in Flash Builder emulate Flex Builders 'Flex navigator' window?
Bottom line is I don't always need to peer into SWC's, and I don't like having a 'default package' automatically created for me. Not sure why the interface wasn't made simpler, allowing access to more power and complexity only if necessary. I want to focus on the code, not on how to navigate and use the bells and whistles in the coding environment.

I have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based? I am hoping that there is a plugin somewhere or maybe html5 has some magic in there that supports it.

i've got a few fonts embedded and am using them in my mobile application, and they are all working, except for the ones i try to use for the "ActionBar". They work everywhere else, and substituting "Comic Sans MS" for "titleCGF" changes it to Comic Sans. So why won't it work with my custom fontFamily?

I have a flex mobile application that I am working on that I am having issues with selecting an image from roll/taking a picture. My application is not tabbed, however one part of it contains a Tabbed View Navigator with tabs across the bottom. Within one of those tabs, I have the ability to upload an image to a webservice that I have created. However, when I select an image or take the picture, it pops back out to the initial splash screen and the application restarts. If I use the component standalone (outside of the tabbed view navigator) it selects the image and uploads without any problem.
