NAME
macsheet - Custom, Mac-native "sheet" windows
SYNPOSIS
package require macsheet
macsheet::sheet parent? sheet?
macsheet::closesheet sheet?
DESCRIPTION
This package implements Mac-native "sheet" windows for Tk. "Sheet" windows are dialogs or toplevel windows that slide down from the top of a Mac toplevel window, and then slide back up when they are dismissed. Tk on the Mac has long supported the "sheet" effect for system dialogs, such as tk_messageBox, when a "-parent" option is passed to the call. The macsheet package adds the ability to create customized dialogs or windows with a similar effect.
LIMITATIONS
Some experimenting with window layout may be necessary to achieve a visually pleasing appearance with a sheet. Also, because of some differences in how the Mac/Cocoa frameworks implement the sheet animation and how Tk manages window geometry, the "sliding down" effect is not perfectly achieved; the "sliding up" effect works fine.
EXAMPLE
package require macsheet
button .b -text "Run Sheet" -command sheetf
pack .b
proc sheetf {} {
toplevel .f
label .f.l -bg red -text "Sheet"
pack .f.l -fill both -expand yes
button .f.b -text "Close Sheet" -command [list macsheet::closesheet .f]
pack .f.b -fill both -expand yes
macsheet::sheet . .f
}
