tk_dialog - Create modal dialog and wait for response
tk_dialog window title text bitmap default string string ...
This procedure is part of the Tk script library. Its arguments describe a dialog
- Name of top-level window to use for dialog. Any existing window by this
name is destroyed.
- Text to appear in the window manager's title bar for the dialog.
- Message to appear in the top portion of the dialog box.
- If non-empty, specifies a bitmap to display in the top portion of the
dialog, to the left of the text. If this is an empty string then no bitmap
is displayed in the dialog.
- If this is an integer greater than or equal to zero, then it gives the
index of the button that is to be the default button for the dialog (0 for
the leftmost button, and so on). If less than zero or an empty string then
there will not be any default button.
- There will be one button for each of these arguments. Each string
specifies text to display in a button, in order from left to right.
After creating a dialog box, tk_dialog
waits for the user to select one
of the buttons either by clicking on the button with the mouse or by typing
return to invoke the default button (if any). Then it returns the index of the
selected button: 0 for the leftmost button, 1 for the button next to it, and
so on. If the dialog's window is destroyed before the user selects one of the
buttons, then -1 is returned.
While waiting for the user to respond, tk_dialog
sets a local grab. This
prevents the user from interacting with the application in any way except to
invoke the dialog box.
