hello
i refer to the "rpnoble" question:
((((In the Draw.pl example, all program action takes place in the timer
event. Is
there a way to trigger a default program action without using the timer
event once the program has called Win32::GUI::Dialog()? In all of my
win32::GUI programs, I use a menu or button to start action.
))))))
here is a not optimized code which display a black rectangle and a red line
whith thickness "2" upon a click on a button , and erase the draw upon the
click of another button, i have cut the code from a very long file .
the only problem with the draw is that it is erased when we cover it whith
another window.
use Win32::GUI;
my $mw = new Win32::GUI::Window(
-left => 0,
-top => 0,
-width => 638,
-height => 478,
-name => "mw",
);
$mw->AddButton(
-name => "Button1",
-text => "RUN ",
-pos => [ 0, 0 ],
);
$mw->AddButton(
-name => "Button2",
-text => "CLS ",
-pos => [ 0, 30 ],
);
$mw->Show();
Win32::GUI::Dialog();
sub Window_Terminate {
return -1;
}
sub Button1_Click {
my $DC = $mw->GetDC;
my @colrB = "0,0,0"; #color of background
$x=0; $y=0;
@colrBR= map { split ',', $_ } @colrB;
$P = new Win32::GUI::Pen(
-color => [ @colrBR],
-width => 1,
);
$B = new Win32::GUI::Brush(
[EMAIL PROTECTED]
);
$oldP = $DC->SelectObject($P);
$oldB = $DC->SelectObject($B);
$DC->Rectangle(70, 45, 300, 200);
my @colrF = "245, 56, 10"; #color of Foreground
$pointsize = "2";
@colrFR= map { split ',', $_ } @colrF;
for (my $i= 1; $i <= 400; $i += 1) {
$P = new Win32::GUI::Pen(
-color => [ @colrFR],
-width => 1,
);
$B = new Win32::GUI::Brush(
[ @colrFR]
);
$oldP = $DC->SelectObject($P);
$oldB = $DC->SelectObject($B);
$x+=1; $y+=1;
$DC->Circle($x, $y,$pointsize);
}
}
sub Button2_Click {
$mw -> InvalidateRect(1);
}
