Tweetanium/Struct window loading on device

I'm using Struct to build an app, a port of Tweentanium, and I'm using Struct with native tabs (https://github.com/krawaller/Struct/tree/nativetabs).

The issue I'm running into is that when a new window is called to open on the actual device, it takes 1-3 seconds for the window to load, and then the window slides to open after all the views have loaded. This is problematic because you click a button for a new window to load and then the app just sits there for a few seconds and appears to not work... so a user might click open several times in a row.

This doesnt happen on the iOS simulator (which runs like a dream), but on the actual device, there is the 1-3 second delay.

Has anyone else noticed this issue? Right now my solution is to put a setTimeout on the window to a half second before it loads any tableviews or other views, but that seems like a lame hack.

I had a similar delay on loading a few pages after using the Tibar module and processing the information. The solution that the team I work with used was to create a loading bar using an image view similar to the following:

var screen_imageView_loadingBar = Titanium.UI.createImageView({ images:screen_array_images, duration:100, repeatCount:0, //infinitely repeat top:, left: , zIndex: });

Then you can show the user information is processing without making many changes to your current working functionality.

I tried something a bit different that makes it so I don't need for a preloader to appear when I open a new page.

I think the issue is, my global function to run the window has to run before the tab.open() function gets called.

Instead of creating the Window inside of my global function, I create the window outside of the function and instead pass the window as a parameter.

var browseWindow = Titanium.UI.createWindow({  
 title:'Browse',
 barColor:'#5f320c',
 barImage:'/content/images/bars/top.png',
 backgroundImage: '/content/images/bg.png'
});
 
 
homeTab.open(browseWindow, {animated:true});
 
// call to my global function to pass the window      
tt.ui.createBrowseView( browseWindow );

This seems to work better and the windows slides to open almost instantly on the device, although I'm not positive that this doesn't create any memory leak issues.
