in reply to WIN32::GUI label font/color

Not very elegant, but it works. The basic idea is to simply replace the label by creating a new one with the same name. To avoid artifacts, you can hide the original first.

#!/usr/bin/winperl use warnings; use strict; use Win32::GUI; my $w = Win32::GUI::Window->new( -title => "Win32::GUI::Label test", -left => 100, -top => 100, -width => 100, -height => 100, -name => "Window", ); my $font = 0; my @fonts = ( Win32::GUI::Font->new( -name => 'Arial', -size => 14, -bold => 1, ), Win32::GUI::Font->new( -name => 'Arial', -size => 14, -italic => 1, ), ); my @colors = ([0, 0, 0], [255, 0, 0]); my @label_data = ( -name => "Label", -left => 30, -top => 10, -text => "Test", ); my $l = $w->AddLabel( @label_data, -font => $fonts[$font], -foreground => $colors[$font], ); $w->AddButton( -name => 'Button', -text => 'Change Font', -left => 10, -top => 45, ); $w->Show(); Win32::GUI::Dialog(); sub Window_Terminate { return -1; } sub Button_Click { $font = ($font+1) % @fonts; $l->Hide(); $l = $w->AddLabel( @label_data, -font => $fonts[$font], -foreground => $colors[$font], ); }

The basic idea came from the How-To.

    At least changing the color (example to Red) can (now) be achieved with similar logic to: labelobject->Change(-foreground => 255,0,0); labelobject->Redraw(1); and labelobject is Win32::GUI label.

[Corion]: Maybe the solution would be a tablet (with pens), like the Wacom tablets, but you still need good software and need to know how to operate it well in an interactive setting ;)
[ambrus]: Corion: the solution depends on who for. Some non-math presentations need to show lots of graphics or photos, with fine details and color. For those, blackboard or overhead transparencies aren't so good (yes, you can print on transparencies, but there's s
[ambrus]: ome quality limits), but film projection or computer projector is fine.
[ambrus]: A minority of math presenters are traditional and don't want to operate a computer. For them, handwritten overhead transparencies and blackboard are fine.
[Corion]: BTW, has anybody seen the Microsoft Surface Studio thing live?
[ambrus]: Some will operate a computer, but want to operate crazy unusable android-like GUIs. For those, printed overhead transparencies or simple slide editors and maybe even tablets are fine.
