Asking a question with confirmDialog

The confirmDialog command creates a modal window with a message to the user and any number of buttons.

The window disappears when the user presses any button or clicks the window’s close button.

• Use the message flag to set the text string that appears above the buttons.
• Add a button flag with the title string of each button.
• Use the defaultButton flag to specify which button corresponds to the key.
• Use the cancelButton flag to specify which button corresponds to the key.
• If the user clicks a button, the name of the button is returned.
• If the user clicks the window’s close button, the string specified by the dismissString flag is returned.
  

confirmDialog -title "Confirm" -message "Are you sure?"
	-button "OK" -button "Cancel" -defaultButton "OK"
	-cancelButton "Cancel" -dismissString "Cancel";

Letting the user choose a file with fileDialog

The fileDialog command shows a file open dialog window.

• Use the directoryMask flag to specify the starting directory and a filename filter. If you don’t use this flag, the file dialog starts in the current working directory.

  The string may contain a path name, and must contain a wildcard file specifier. (for example "*.cc" or "/usr/u/*").

• The command returns the path of the file the user chose, or an empty string if the user cancels the file dialog.
  

fileDialog -directoryMask "*.txt"

Getting a string with promptDialog

The promptDialog command creates a window with a message to the user, a text box, and any number of buttons.

• Use the title flag to set the window title. Use the message flag to set the string that appears above the text box and buttons.
• Use the text flag to set the initial contents of the text box. Use the scrollableField flag to change the text box to a multi-line scroll field.
• Add a button flag with the title string of each button.
• Use the defaultButton flag to specify which button corresponds to the key.
• Use the cancelButton flag to specify which button corresponds to the key.
• If the user clicks a button, the name of the button is returned.
• If the user clicks the window’s close button, the string specified by the dismissString flag is returned.
• After the command returns, use the command again with query flag and the text flag to get the text the user entered.
  

// Show the dialog box:
string $text;
string $result = `promptDialog
	-title "Rename Object"
	-message "Enter Name:"
	-button "OK" -button "Cancel"
	-defaultButton "OK" -cancelButton "Cancel"
	-dismissString "Cancel"`;
// Use the command again in query mode to
// get the text:
if ($result == "OK") {
	$text = `promptDialog -query -text`;
}
