How to detect when a button has been pressed

[NewsArchive]

Take the Install Folder window for example, how can I detect when the Back,
Next, Cancel or Change buttons are pressed and code something to do at that
point.

For example, whenever Back is pressed I need to reset a variable to a
default value. Equally when Next or Change is pressed I need to append a
value to the install folder selected.

I can use Set Focus to ControlID $edit_Data1$ for example, but this is not
the same as detecting a button has been actioned.

TIA

If you press BACK, the variable %_SB_BUTTONID% returns $BACK_BTN$ and if you
click NEXT, the variable %_SB_BUTTONID% returns $NEXT_BTN$. The "Browse..."
button in a standard "Select Install Folder" does not execute any script
action (you can create your own Select Install Folder dialog to handle this)
or you can validate the before/after value of $_SB_INSTALLDIR$ to detect
changes.

The CANCEL button never executes any script action in SB7.

Hope this helps.

John,

There are additional tricks in the example files, some of which are
explained in "Learning SetupBuilder Part I"

For example,
in the latter file, look through the descriptions for
Custom Dialog 1 Demo - button,
Custom Dialog 1 Demo - Check Boxes for the on init event
Custom Dialog 2 Demo for the newselection event
Custom Dialog 3 Demo for the onupdate event

etc.
