ios text objects
Posted: Thu Mar 20, 2014 2:45 am
I have used a basic livecode field in an app designed for ios.
It has the following capabilities -
- can be locked - allows users to scroll and select a line which then changes the contents of another text field
- can be unlocked - users can then enter text as required
- its contents can be set by scripts on other objects, e.g. inserting text from the custom properties of a field on another card
- its contents can be referenced by line, word, item etc to manipulate the contents in a variety of ways.
It works perfectly but doesn't look 'native' on an ipad.
I've tried using a multiline object from mobgui (ver 0.29) but can not get it to function as above.
e.g. I spent ages on 'mgtext' before finding out that 'utext' works better.
LockText is particularly useful for standard fields but doesn't apply to multiline objects.
What type of object should I be using?
What commands and properties would I use to control it?

LiveCode fields can be visually changed to replicate the look and feel of Native mobile fields. There are various properties of a LiveCode field that you can disable to achieve this and these can be easily accessed via an objects property inspector. These are-
You can also turn opaque off and use a graphic object as a background to your field. This could give a more visually appealing mobile look (e.g.rounded rectangle graphic)
