The ticks are always red, and option box labels are in green background and the checkbutton label background is pinkish. If, however, you prolong your mouse click, you see all the colors reverting to that gray Tk default temporarily while you hold the mouse button down. DrS

The visual change for the radio and check button indicators followed the attempt to "revitalize" Tk under X11 --prior to tile--. This vitualized designs are the same as being used by Windows 95. I guess the rational for this particular choice was: Microsoft sells so much copies of Windows it must be due to the visual quality of its GUI. As an ironic sidenote: Micosoft has almost corrected their indicators and highlighting in Vista, which is now similar to the original motif-look, albeit highlighting is still inside the control. >It is not clear to me whether the "Under Windows" means "when the Tk >application runs on Windows" or if it means "when the Tk application >DISPLAYS on Windows". > >In our case, the applications are running on a Solaris machine, >displaying back to a Windows machine via Cygwin/X . > >I'm just wondering whether the difference we are seeing reflects a >change in Tk which has not yet made it to the man page, a bug in Tk >8.5 and 8.6, or a problem when Tk 8.5 displays back to a Windows-based >X server. > > > Both: the property selectcolor should reflect a state change. The property name should have changed in 8.5 to something like indicatorBackground. -roger -- http://gestaltitems.sourceforge.net/geitems/Gstripes_Controls.html#d0e2628

The bug maintainer did notice the discrepancy and suggested as much as to reopen it as a documentation bug. quotation from the bug erport: ....maybe only the *documentation* needs to be changed, to say that "selectcolor" now means the background color of the indicator, ... I say the property name has to be indicatorBackground, not selectcolor. Abusing selectcolor for the indicator background was a long tolerated hack under windows (ms), changing the complet behaviour requires to remove this hack. -roger

The critical part is the altered behavior: In motif and tk 8.4 there are two types of radio and checkbuttons grouped without indicators and stand-alone with indicators. The indicator checkbutton must be a iconic representation of a grouped checkbutton. Microsoft Windows and all other windowing systems feature grouped radio and checkuttons, today. This is the reason why microsoft switched to the motif look-a-like versions in Vista, albeit seeing to some historic resemblance... The windows 95 versions were called checkentry and radioentry, making them akin to the entry windows --OK for Windows 95. -roger |
