Hi,
I am writing my logic code in a separate thread, then the thread calls some UI callback functions to display some prompt messages and also respond keypad and touch action. Some thing like this,
1. Do something
2. Pop up a prompt message to indicate the result and next instruction
3. Wait for key pressed or touch action
4. If Key pressed, hide or destroy the prompt and back to main screen
Note: in main screen, touch and key are also supported, but the action response is absolutely different from that with prompt.
UI callbacks for key, touch and message show/hide
void TestSetKey(uint32_t key);
void TestSetTouch(void);
void ShowTestUIMsg(Test_UI_Message *pMsg, uint32 count, uint32 bk_color);
void HideTestUIMsg(void);
What I am trying is create a prompt class to add some text box and draw the background, and add simple touch handler, key press handler. This prompt class will be createdin class application, that is the main screen. By default, BeginModal() will not be called for not respond key and touch , and the prompt is invisable. So the question is how do I implement ShowTestUIMsg() and HideTestUIMsg() to let GUI to show or hide the prompt and respond key or touch?
