I would like to report two problems with the ->geometry method. 1. The ->geometry method returns incorrect (old?) window position when maximized. To reproduce, run the attached code, Maximize the window, then press "Get Current Geometry". When I do this, the "window position" portion of the geometry string shows the previous window position. The "window size" portion appears to be correct. 2. The ->geometry method returns invalid geometry string when window position contains negative values. To reproduce, run the attached code, move the edge of the window off the upper left side of the screen, click "Get Current Geometry". When I do this, the geometry string shows +-xxx+-yyy. Shouldn't it show -xxx-yyy? The '+' and '-' shouldn't show at the same time should it? Perhaps something is wrong on my side? Sample Code: #!/usr/bin/perl use Tk; my $mw = MainWindow->new(); $mw->withdraw(); $mw->title("Show Current Geometry"); my $button = $mw->Button( -text => 'Get Current Geometry', -command => \&get_geo, )->pack( -expand => 1, ); my $frame = $mw->Label( )->pack( -expand => 1, ); $mw->deiconify(); $mw->update(); get_geo(); MainLoop(); exit(0); sub get_geo { $mw->update(); $frame->configure(-text => 'Geo: ' . $mw->geometry . ' x: ' . $mw->x . ' y: ' . $mw->y); return(1); } __END__ Operating System: Windows XP PerlTk Version: 804.029 (from activestate repository) Using: Active State Perl v5.12.4, built for MSWin32-x86-multi-thread Summary of my perl5 (revision 5 version 12 subversion 4) configuration: Platform: osname=MSWin32, osvers=5.2, archname=MSWin32-x86-multi-thread uname='' config_args='undef' hint=recommended, useposix=true, d_sigaction=undef useithreads=define, usemultiplicity=define useperlio=define, d_sfio=undef, uselargefiles=define, usesocks=undef use64bitint=undef, use64bitall=undef, uselongdouble=undef usemymalloc=n, bincompat5005=undef Compiler: cc='c:/MinGW/bin/gcc.exe', ccflags ='-DNDEBUG -DWIN32 -D_CONSOLE -DNO_STRICT -DHAVE_DES_FCRYPT -DUSE_SITECUSTOMIZE -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DUSE_PERLIO -D_USE_32BIT_TIME_T -DPERL_MSVCRT_READFIX -DHASATTRIBUTE -fno-strict-aliasing -mms-bitfields', optimize='-O2', cppflags='-DWIN32' ccversion='', gccversion='4.5.2', gccosandvers='' intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=1234 d_longlong=undef, longlongsize=8, d_longdbl=define, longdblsize=8 ivtype='long', ivsize=4, nvtype='double', nvsize=8, Off_t='__int64', lseeksize=8 alignbytes=8, prototype=define Linker and Libraries: ld='c:\MinGW\bin\g++.exe', ldflags ='-L"C:\Perl\lib\CORE"' libpth=\lib libs=-lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -lnetapi32 -luuid -lws2_32 -lmpr -lwinmm -lversion -lodbc32 -lodbccp32 -lcomctl32 -lmsvcrt perllibs=-lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -lnetapi32 -luuid -lws2_32 -lmpr -lwinmm -lversion -lodbc32 -lodbccp32 -lcomctl32 -lmsvcrt libc=msvcrt.lib, so=dll, useshrplib=true, libperl=perl512.lib gnulibc_version='' Dynamic Linking: dlsrc=dl_win32.xs, dlext=dll, d_dlsymun=undef, ccdlflags=' ' cccdlflags=' ', lddlflags='-mdll -L"C:\Perl\lib\CORE"' Characteristics of this binary (from libperl): Compile-time options: MULTIPLICITY PERL_DONT_CREATE_GVSV PERL_IMPLICIT_CONTEXT PERL_IMPLICIT_SYS PERL_MALLOC_WRAP PL_OP_SLAB_ALLOC USE_ITHREADS USE_LARGE_FILES USE_PERLIO USE_PERL_ATOF USE_SITECUSTOMIZE Locally applied patches: ActivePerl Build 1205 [294981] c6fbf28 [perl #71806] perldb does not setup %dbline with the shebang option -d 1fd8fa4 Add Wolfram Humann to AUTHORS f120055 make string-append on win32 100 times faster a2a8d15 Define _USE_32BIT_TIME_T for VC6 and VC7 007cfe1 Don't pretend to support really old VC++ compilers 6d8f7c9 Get rid of obsolete PerlCRT.dll support d956618 Make Term::ReadLine::findConsole fall back to STDIN if /dev/tty can't be opened 321e50c Escape patch strings before embedding them in patchlevel.h Built under MSWin32 Compiled at Jun 20 2011 18:35:25 @INC: C:/Perl/site/lib C:/Perl/lib .

Hi Michael, I can confirm the first problem (just tried with StrawberryPerl 5.18.1.1). The 2nd problem is not a problem, the "+-xxx" is intended. Traditionally in X11 a negative coordinate value means "from right/bottom" instead "from left/top". For example, a user may attach a X11 program to the right bottom corner by using "/path/to/program -geometry -0-0". So real negative values have to be expressed differently, therefore the somewhat strange "+-" notation. Regards, Slaven

ad 1: Tcl/Tk 8.5 has the same problem, it seems. I tried with the following script: button .b -text "get current geometry" -command { set current_geom [wm geometry .] } label .l -textvariable current_geom pack .b pack .l Regards, Slaven
