What methods are there to set the value of a text widget?
Also, .mainFrame's size keeps changing; how can I keep it constant?
Code:
#!/usr/bin/wish
# Set the fortune into place
proc centerWindow {w} {
set width 500
set height 500
set x [expr { ( [winfo vrootwidth $w] - $width ) / 2 }]
set y [expr { ( [winfo vrootheight $w] - $height ) / 2 }]
wm geometry $w ${width}x${height}+${x}+${y}
}
proc newFortune {n} {
set fortune [exec fortune]
set date [exec date +%H:%m:%S]
if {$n == 1} {destroy .mainFrame.textFrame.fort}
set fort [text .mainFrame.textFrame.fort -yscrollcommand {.mainFrame.textFrame.scroll set} -setgrid true -borderwidth 2 -state disabled -wrap word]
pack .mainFrame.textFrame.fort -side left -fill both -expand true
if {$n == 1} {destroy .mainFrame.timeFrame.time }
label .mainFrame.timeFrame.time -foreground red -text $date
pack .mainFrame.timeFrame.time
if {$n == 1} { destroy .mainFrame.piX }
label .mainFrame.piX -text [winfo geometry .mainFrame]
pack .mainFrame.piX
}
# Setup Window
wm withdraw .
toplevel .mainFrame -height 900 -width 900
wm title .mainFrame "Fortune"
wm resizable .mainFrame false false
# Create widgets
frame .mainFrame.timeFrame -pady 5 -padx 5
frame .mainFrame.textFrame -pady 5 -padx 0 -height 30 -width 50
scrollbar .mainFrame.textFrame.scroll -command {.mainFrame.textFrame.fort yview}
frame .mainFrame.buttonFrame -pady 5 -padx 5
button .mainFrame.buttonFrame.close -command "destroy ." -text "Close"
button .mainFrame.buttonFrame.next -text "Next" -command "newFortune 1"
# Finalize display
centerWindow .mainFrame
pack .mainFrame.timeFrame
pack .mainFrame.textFrame
newFortune 0
pack .mainFrame.textFrame.scroll -side right -fill y
pack .mainFrame.textFrame.fort -side left -fill both -expand true
pack .mainFrame.buttonFrame
pack .mainFrame.buttonFrame.next -side left
pack .mainFrame.buttonFrame.close -side right
