Per modificare le dimensioni della finestra di un programma esterno si può utilizzare la funzione XResizeWindow() della libreria condivisa (nella sua attuale versione) libX11.so.6.3.0 .
Tale funzione esterna non modifica le dimensioni dei bordi della finestra, e richiede, fra l'altro, la specificazione del numero identificativo della finestra del programma da chiudere.
Mostriamo un esempio essenziale:
Library "libX11:6.3.0" ' Display *XOpenDisplay(char *display_name) ' Opens a connection to the X server that controls a display. Private Extern XOpenDisplay(display$ As String) As Pointer ' XResizeWindow(Display *display, Window w, unsigned int x, unsigned int y) ' Changes the inside dimensions of the specified window, not including its borders. Private Extern XResizeWindow(displayP As Pointer, w As Integer, width As Integer, height As Integer) ' XCloseDisplay(Display *display) ' Closes the connection to the X server for the display specified in the Display structure and destroys all windows. Private Extern XCloseDisplay(displayP As Pointer) Public Sub Main() Dim disp As Pointer ' Connessione al server X ed impostazione di default: disp = XOpenDisplay(Null) XResizeWindow(disp, num_ID_della_finestra, 50, 200) ' Chiude la libreria: XCloseDisplay(disp) End
