Numeric input enable button at runtime
When the operator presses the numeric input enable button, the numeric pop-up scratchpad opens.
TIP:
On mobile operating systems and
Windows
10 operating systems, the device scratchpad appears automatically when a numeric input enable button is selected.The operator types a numeric value in the pop-up and presses Enter. The value is sent to the Value connection at the data source.
If a write expression is assigned, the application evaluates the expression and sends the expression value to the Value connection.
TIP:
Timing and Handshaking are not supported. Optional Expression and Enter connections are not supported.
Ramping
If the button has input focus, you can press a Move Up Key button object or a cursor up key on an external keyboard or keypad to increase the Value connection by the ramp value, or press a Move Down Key button object or a cursor down key to decrease the Value connection by the ramp value.
The button does not need to have input focus to call a pop-up. It does have to have input focus to perform the ramping function. If you want the button to have input focus when pressed, select the
Take Focus on Press
checkbox (on the General
tab). Select the Key Navigation
checkbox (on the General
tab) if you want the operator to be able to navigate to the button with the keyboard and give the button input focus.Provide Feedback
