From Tk 8.4 on, Tk has its own panedwindow.
Examples on use of BWidget::PanedWindow:
package require BWidget # Create PanedWindow with 3 horizontal panes set pwh [PanedWindow .pwh -side top] pack $pwh -fill both -expand true set fh1 [$pwh add] set fh2 [$pwh add] set fh3 [$pwh add] # In second pane, add 2 horizontal panes set pwv [PanedWindow $fh2.pwv -side left] pack $pwv -fill both -expand true set fv1 [$pwv add] set fv2 [$pwv add] # Make large enough to be able to resize the panes wm geometry . 500x500
Jos Decoster The following examples show the difference between extra and available values for the -weights option. You can compare this option with the -stretch option of the Tk 8.5 panedwindow widget.
package require BWidget wm geometry . 500x500+200+200 set f1 [frame .f1] set f2 [frame .f2] pack .f1 .f2 -fill both -expand true # Create 3 panes where only extra space is divided among the different panes # relative to their weight. set pwh1 [PanedWindow $f1.pwh -side top -weights extra] pack $pwh1 -fill both -expand true set fh1_1 [$pwh1 add -weight 2] pack [text $fh1_1.txt] -fill both -expand true set fh1_2 [$pwh1 add -weight 2] pack [text $fh1_2.txt] -fill both -expand true set fh1_3 [$pwh1 add -weight 1] pack [text $fh1_3.txt] -fill both -expand true # Create 3 panes where all space is divided among the different panes # relative to their weight. set pwh2 [PanedWindow $f2.pwh -side top -weights available] pack $pwh2 -fill both -expand true set fh2_1 [$pwh2 add -weight 2] pack [text $fh2_1.txt] -fill both -expand true set fh2_2 [$pwh2 add -weight 2] pack [text $fh2_2.txt] -fill both -expand true set fh2_3 [$pwh2 add -weight 1] pack [text $fh2_3.txt] -fill both -expand true
