fallbacks, added emergency font as an asset, added graceful

BUILDING FLTK SAMPLE WITH ANDROID STUDIO 3
|
|
------------------------------------------
|
|
|
|
There is no need to ever write a single line of Java.
|
|
|
|
Download and install AndroidStudio on your developer machine. If you use
|
|
AndroidStudio for the first time, use the IDE to download and build the
|
|
"Native Plasm" sample app. In the process, all resources required to build
|
|
FLTK will be installed. Once Native Plasm runs on your emulator or physical
|
|
device, you are ready to install FLTK.
|
|
|
|
- if your host machine runs MSWindows, rename the file
|
|
"ide/AndroidStudio3/gradlew.rename_to_bat" to "gradlew.bat" first
|
|
|
|
- open the "ide/AndroidStudio3/" directory as a project in AndroidStudio
|
|
|
|
- click "run"; the project should compile and run out of the box
|
|
|
|
|
|
Extensions and limitation of FLTK on Android
|
|
--------------------------------------------
|
|
|
|
Android support for FLTK is in a very early stage. As of March 2018, very basic
|
|
rendering works, text rendering work, clipping works, window layering works,
|
|
and mouse clicks (touch events) are detected.
|
|
|
|
When loading fonts:
|
|
- font names starting with a $ will have the system font path inserted
|
|
- font names starting with an @ will be loaded via the Asset Manager
|
|
- all other names will be used verbatim
|
|
|
|
Limitations:
|
|
- the screen size is currently fixed to 600x800 and is scaled up
|
|
- many many big and little functions are not yet implemented
|
|
