Casio IT-2000W manual Input acceptance mode, Toggle function, Repeat function, Key click sound

Input acceptance mode

￿There are two acceptance modes for key input.

Down acceptance mode

When the pen is down on the keypad, the touched area changes to reverse video, and the corresponding keycode is generated. The reverse video area will return to normal when the pen is up. Even if the pen runs outside the corresponding key area in the mid course, the reverse video

￿area continues as-is.

Up acceptance mode

When the pen is down on the keypad, the touched area changes to reverse video. If the pen runs outside the firstly touched area, the first reverse video area is canceled and a new area will change to reverse video. When the pen is up, a keycode corresponding to the current reverse video area will be generated. When the pen is up outside the keypad, the current key input operation will be invalidated.

Toggle function

When the Expansion button on the keypad (upper case alphabets or lower-case alphabets pad) is touched, the expansion keypad becomes the active pad. This keypad returns to the previous screen after only a single key input is made, unless the touched area is assigned no keycode.

Repeat function

The repeat function allows all the successive key inputs before the pen is up to be accepted in a lump. This function is valid only in the Down acceptance mode.

Key click sound

A key sensing sound is always generated whenever the keypad is touched (Down operation) irrespective of the current input acceptance mode. However, it is of course on this keypad the valid keycodes should have been set. In the Up acceptance mode if the pen is down to an invalid key area and it runs over another valid key area, the key sensing sound will not be generated.

How to use with a VC application

In order to develop an application program that utilizes the keypad library with the VC, it is necessary to register the keypad library to AppStadio. The following example shows a screen of Microsoft Visual C++ver. 1.51.
