Adding logic to control objects
User Defined events can include parameters to supply more information to be used within
the action. Since parametrized User Defined events are only likely to be used in very
specific cases, what follows is a generic example with a control panel. It shows how to set
text from one text box to the next and change it along the way by clicking a button.
To create a panel using parametrized User Defined events:
1.
Create a new control panel with three (3) text boxes and a button.
2. Select T EXTBOX 2 and then display the A CTION E DITOR (CTRL + E).
You will create a new event for Textbox2.
3. From the E VENTS drop-down list, select U SER D EFINED and then click the A DD E VENT
button to the right of the drop-down list.
4. In the A DD E VENT dialog box, type a name for the event followed immediately by in
parentheses into which you will enter a parameter name. For example,
MyEvents(text)
. Then click OK and the custom event is added immediately to the
Events List.
5. You will now assign a S END E VENT action to the button object. This will send the new
event to Textbox2.
a.
Select the button object on the control panel.
b. Select O N C LICK from the Event list.
c. Select the S END E VENT action from the A CTIONS drop-down list and click the A DD
A CTIONS button.
The Send Event is immediately added to the Action Table.
6. In the A CTION P ARAMETERS , enter the name of your event in the E VENT T YPE field
followed by a parentheses into which you will enter Control:Textbox1. For
example, MyEvent(Control:Textbox1).
This means that whatever text is entered in Textbox1 becomes the parameter for the
U
SER D EFINED event.
7. Enter Control:Textbox2 in the Action Parameter’s T ARGET field.
