| Description: |
The attached patch is a demo for Win2K/XP alpha transparency for entire toplevels. While cool looking ... it's all relatively useless outside of demos and splash screens. I attach it here for reference. Made against win/tkWinWm.c of 8.5a0. | |||

This sample script has a fade out test:
console show
# A start value of 0.99 ensures that we avoid the
# window class switch "blink"
wm attributes . -alpha 0.99
bind . <FocusIn> { wm attributes . -alpha 0.99 }
bind . <FocusOut> { fade %W 0.99 }
proc fade {w val {min 0.5} {decr 0.03} {delay 50}} {
catch {after cancel $::ID}
if {$val > $min} {
set val [expr {$val - $decr}]
wm attributes $w -alpha $val
}
set ::ID [after $delay \
[lreplace [info level 0] 2 2 $val]]
}

This aligns with Aqua alpha usage, and enables generally better granularity. andreas_kupries added on 2004-09-17 05:42:46: Logged In: YES user_id=75003 This has been proposed to the TCT as "http://tip.tcl.tk/222". hobbs added on 2004-09-17 03:09:14: File Deleted - 101646: File Added - 101750: alphatranwin2.diff hobbs added on 2004-09-17 03:09:13: Logged In: YES user_id=72656 Update of my patch to add the tkWinInt.h changes, and with improvements to reduce calls to UpdateWrapper and use the right Z order when updating wrapper. hobbs added on 2004-09-16 07:00:21: File Added - 101646: alphatranwin2.diff hobbs added on 2004-09-16 07:00:20: Logged In: YES user_id=72656 An update to the previous patch that creates an alternate window class style to handle transparent windows. It accepts (opaque 0..100 (transparent) as the %age transparent value. This should be tipped up for 8.5. It handles the cases where layered windows aren't available. hobbs added on 2004-02-07 07:58:51: File Added - 75984: alphatranwin.diff | |||
