Fork of DMBasicGUI by Embedded Artists

Application/ImageButton.cpp@17:6e2abf107800, 2015-03-20 (annotated)

Committer:
embeddedartists
Date:
Fri Mar 20 14:25:46 2015 +0100
Revision:
17:6e2abf107800
Parent:
11:265884fa7fdd
Child:
25:9528217a6c39
- Added a Resource concept to allow runtime selection of image source. The

  resource can be loaded from an array in flash or from a file on any of the

  available file systems. Using a resource makes it possible to have different

  resources depending on display resolution

- Removed the basic_image data files

- Added support for the 5" display (800x480 resolution)

- Added possibility to change the default font in SWIM
