Hello!<br>
<br>
For example, there is small bug corresponding to this problem. See
function «ImplDrawDropdownArrow» in «toolbox.cxx» («vcl» module).<br>
A lines<br>
long x = rDropDownRect.Left() + (rDropDownRect.getWidth() -
width)/2;<br>
long y = rDropDownRect.Top() + (rDropDownRect.getHeight() -
height)/2;<br>
<br>
use wrong functions getHeight() and getWidth() , but really should
use GetHeight() and GetWidth(). <br>
So, this problem causes the dropdown arrows of menubuttons on
toolboxes to be shifted left.<br>
<br>

<pre wrap="">Hi Dmitry - yes, the two different methods are surely confusing. As
for the "wrong value", that very much depends on the mental model of
rectangles you're using. In a discrete geometry world (aka "pixel"),
the GetWidth() is correct. In a continuous geometry world (aka
"euclidean plane"), getWidth() is right.

Ho ;-) Should we perhaps have some better naming: 'getOuterWidth' vs.
'getWidth' or something ;-)

True - perhaps we should audit all calls of GetWidth on Rectangle to
see how many there are and update them if fewer than a couple of hundred
or so ?
ATB,
