addmenu - interactive button or menu definition

Calling Sequence

addmenu(button [,submenus] [,action])

addmenu(gwin,button [,submenus] [,action])

Parameters

• button : a character string. The button name. On Windows operating systems (not X_window), an & can be placed before the character in the name to be used for keyboard shortcut; this character will be underlined on the GUI.
• submenus : a vector of character string. The sub_menus items names
• action : a list with 2 elements action=list(flag,proc_name)
  • flag : an integer (default value is 0)
  • flag==0 the action is defined by a scilab instruction
  • flag==1 the action is defined by a C or Fortran procedure
  • flag==2 : the action is defined by a scilab function
  • proc_name : a character string which gives the name of scilab variable containing the instruction or the name of procedure to call.
• gwin : integer. The number of graphic window where the button is required to be installed

Description

The function allows the user to add new buttons or menus in the main window or graphics windows command panels.

If action argument is not given the action associated with a button must be defined by a scilab instruction given by the character string variable which name is

+ button for a main window command

+ button_gwin for a graphic window command

If action argument is set to 0 proc_name should be the name of a Scilab string vector. Actions associated with the kth sub_menu must be defined by scilab instructions stored in the kth element of the character string variable.

If action argument is set to 1 proc_name designes a C or Fortran procedure, this procedure may be interfaced in Fortran subroutine default/fbutn.f or dynamically linked with scilab using the link function. The C calling sequence is: (char* button_name, int* gwin,int *k)

If action argument is set to 2 proc_name designes a Scilab function. This function calling sequence should be:

+ proc_name(k) for a main window command

+ proc_name(k,gwin) for a graphic window command or a main window command

Examples

addmenu('foo')
foo='disp(''hello'')'

addmenu('Hello',['Franck';'Peter'])
Hello=['disp(''hello Franck'')';'disp(''hello Peter'')']

addmenu(0,'Hello',['Franck';'Peter'])
Hello_0=['disp(''hello Franck'')';'disp(''hello Peter'')']

addmenu('Bye',list(0,'French_Bye'))
French_Bye='disp(''Au revoir'')'
