Subject:     Visual differences with Motif
Date:        Sat, 14 Nov 1998 05:12:57 +0000

I have noticed a few visual differences between Lesstif and Motif that
have been around since at least 0.85, so I figured it was time to speak
up.  The three things that I have noticed are listed below and are
demonstrated in the attached code.

1. Option menu behavior (see option menu)

Motif: A click on the cascade button pops up the pulldown menu (note
that the cascade button does NOT stay depressed).  A second click on the
cascade button pops DOWN the pulldown menu.

Lesstif: A click on the cascade button pops up the pulldown menu (note
that the cascade button stays depressed).  A second click on the cascade
button does nothing.  You must either select an item in the menu or
click outside the widget to pop down the pulldown menu.

2. Multi-line toggle button in a menu (see menubar)

Motif: All toggle buttons in a menu are the same size regardless of the
number of lines of text contained in the labels.

Lesstif: The size of the toggle buttons is proportional to the number of
lines of text contained in the labels.

3. Multi-line toggle button (see checkboxes)

Motif: The toggle button is top-justified with the first line of text in
the label.

Lesstif: The toggle button is vertically centered w.r.t. the label text.

I'll take a crack at fixing these things when I get time, but I'm sure
they can be fixed fairly quickly by one of the core guys.

Regards,
Ken
