Detect key press or key down event

[khalprin]

Is there a way to detect a key press or key down event in any of the installation dialogs? I'd like to handle an F1 key press and show the user some help information.

Dear khalprin,

I am very sorry but it is not possible.

Eventually you can use a button that triggers an action.

Regards.

How would I use a button? I only see actions like showing the next dialog, going back, or closing the dialog?

Dear khalprin,

To capture a custom button selection do the following:

- Open your Dialog with Dialog Editor.
- Add a Button to your dialog (with the following sample code I used the Welcome Dialog)
- Set the ID property of the button as you like (in my sample I used MYBUTTON)
- Double click the button and in the Object Behavior tab set "Return from Dialog" as Perform action.
- Close Dialog Editor and Save your Dialog settings .
- In your main script use the returned value by Display Dialog command.

With the following code snippet I used the value returned by the Welcome Dialog to show a Yes / NO MessageBox.
If the Yes button is selected the control is returned to the dialog, otherwise it will continue with the next dialog

Code: Select all

Set Variable MYCONTINUE to TRUE
while Variable MYCONTINUE Equals TRUE loop
  Display Dialog: welcome, wait for dialog to return (modal)
   
  if Variable WIZARD Equals MYBUTTON
    MessageBox: Debug, Button Pressed!
    if Variable MYCONTINUE Equals YES
      Set Variable MYCONTINUE to TRUE
    else
      Set Variable MYCONTINUE to FALSE
    end
  else
    Set Variable MYCONTINUE to FALSE
  end
wend

Code: Select all
