Displaying a TextInput control’s text as a password in Flex (redux)

We’ve already seen how to get a TextInput control to display its text as a masked password field before in an earlier example, “Displaying a TextInput control’s text as a password in Flex” by setting the displayAsPassword property to true.
The following example will show you how you can listen for the focusIn and focusOut events to toggle the displayAsPassword property so that when the password field has focus the text is displayed as plain text, and when the password field does not have focus the text is displayed as masked text.

Full code after the jump.

Globally setting modal styles in a Flex application

The topic of setting modal styles came up again today so I thought I’d re-share this tip (I previously covered controlling modal styles for the Alert control in an earlier post, “Changing a modal Alert control’s blur, transparency and transparency color”).

The following example shows how you can set the various modal styles (modalTransparencyBlur, modalTransparency, modalTransparencyColor, and modalTransparencyDuration) on the global selector so it propogates to both the Alert control and pop-ups created using the PopUpManager.

Creating custom pop-up windows with the PopUpManager class

The Alert control is great if you need to get a simple confirmation on an action which has a yes/no type answer, but what do you use when you need to prompt a user for their name or something else? JavaScript has a prompt(), and Flex has a very robust PopUpManager class.

This following example will demonstrate how to launch a custom Panel pop-up dialog which includes a Label control, TextInput control, and two Button controls. It also shows how to create a bunch of Flex components and containers using ActionScript instead of MXML.

Modules and singleton manager classes

This is a bit more of a “gotcha” than a tip, but it is something I’ve run into twice in the past week or so. When working with application domains and singletons (such as the DragManager or PopUpManager). I’ve been playing with modules the past couple days and ran into an issue when trying to drag items from a DataGrid in one module to a DataGrid in the second module. When trying to select an item in one of the data grids, I’d get strange run-time errors. The solution? Create a reference in my main application to a dummy DragManager or PopUpManager instance.

Hopefully this will save somebody a little bit of a headache in the future.
