Detailed Description
This application will display an analog and digital clock on the screen.
To adjust the clock, touch the screen continuously for three seconds to enter adjustment mode.
- Note:
- The clock application has not been implemented, hence a pop-up window is shown instead, informing the user about this missing application.
- Todo:
- Implement the clock application and replace the dummy pop-up window.

Function Documentation
| static bool app_clock_frame_command_handler | ( | struct wtk_basic_frame * | frame, | |
| win_command_t | command_data | |||
| ) | [static] |
Frame command handler handling the button events.
- See also:

| static void app_clock_frame_draw_handler | ( | struct win_window * | win, | |
| const struct win_clip_region * | clip | |||
| ) | [static] |
Frame draw handler handling draw events.
This function will draw the contents of the frame to the screen.

| void app_clock_launch | ( | struct workqueue_task * | task | ) |
Launcher for the clock application.
- Parameters:
-
task Workqueue task to use for the application's worker functions.
Variable Documentation
struct app_clock* the_clock_app [static] |
Pointer to the clock application context.
- Note:
- This pointer is statically allocated, but the context itself is only allocated when the application is launched, and then destroyed upon exit to conserve memory.
