Originated in
Troi Dialog Plug-in 1.2
Compatibility
FileMaker Pro 16 to 19
Considerations
If you specify a zero as maxval, an indefinite progress bar is shown (barber pole).
In some cases the time to perform lengthy scripts might increase, as FileMaker updates the screen after the ProgressBar step. A freeze screen step does not always help.
IMPORTANT Use only in a script. Do not use this function in a calculated field definition, because when FileMaker calculates the fields this will result into a repeated dialog for EACH record. Also note that functions that use the clipboard, like pasting in a container field, will not work, as they try to paste in the progress bar window.
See also the Dial_SetPreference function to change the time of automatic removal of a progress dialog.
You can also suppress the title in all ProgressBar dialogs by adding this to your (startup) script:
Dial_SetPreference ( "-TitlesInProgressBarDialogs" ; "off" )This will set the Progress bar title to blank for all subsequent calls until FileMaker is restarted.
Version 8.0 added support for (custom) icons.
Version 9.0 added the “-Floating” switch. This will open the progress bar as a floating window. When using this switch the focus is not tied to the front FileMaker window, enabling to use for example the “New Window” step in the script, the progress dialog will float above the new window. This switch has only effect on Windows.
Example
Use this function to indicate to a user that a script is doing a lengthy operation and provide feedback on how long this operation will last.
