### 3.4 tk-dialog

tk-dialog \- Create modal dialog and wait for response

#### Synopsis

tk-dialog window title text bitmap default string string ...

#### Description

This procedure is part of the Tk script library. Its arguments describe a dialog box:

window

  Name of top-level window to use for dialog. Any existing window by this name is destroyed.

title

  Text to appear in the window manager’s title bar for the dialog.

text

  Message to appear in the top portion of the dialog box.

bitmap

  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.

default

  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 won’t be any default button.

string

  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.

  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.
