Really Miscellaneous Methods
findINC
returns the absolute pathname of a file:
$file = Tk->findINC("Xcamel.gif");
Tk->findINC
searches for files in all Tk
subdirectories of the current @INC
path. This can
also be a personal Tk directory, if it was added with use
lib
or push @INC,...
earlier. If using
the form Tk::findINC
, then only
@INC
is searched, not the subdirectories.
FullScreen
simply makes a Toplevel window as large
as the display. On Win32, this does not include the taskbar area.
$mw->FullScreen;
Getimage
looks for an image with the specified
basename and returns the object reference. The subroutine appends
extensions to the basename in the following order:
xpm
, gif
,
ppm
, xbm
until a valid image is
found. If that fails, built-in images are searched.
$image = $widget->Getimage(name);
tainting
returns a true value if the program is
running with taint checks enabled.
$tainted = $widget->Tk::tainting;
scaling
sets and queries the current scaling
factor used by Tk to convert between physical units (for example,
points, inches, or millimeters) and pixels. The number argument is a
floating-point number that specifies the number of pixels per point
on $widget
’s display. If the number argument
is omitted, the current value of the scaling factor is returned.
A point is a unit of measurement equal to 1/72 inch. A scaling factor of 1.0 corresponds to 1 pixel per point, which is equivalent to a standard 72 dpi monitor. A scaling factor of 1.25 would mean 1.25 pixels per point, ...
