It is not the setWidthPx that needs to be after the setFont, it is the
getTextSizePx method. And the getTextSizePx() has to be invoked on the
list box, not on the dialog:
*-- set the font for the list box*
lb = self~newListBox('IDC_LB_CITIES')
max = 10
items = .array~of("New York New York"~copies(9), -
"San Diego California"~copies(8), -
"Los Angles Californiz"~copies(10), -
"Bakersfield California"~copies(11), -
"San Jose")
do city over items
s = *lb~getTextSizePx(city)*
if s~width > max then max = s~width
lb~insert( , city)
end
lb~setWidthPx(max)
In the above, getTextSizePx() will use the font of the list box to
calculate the size.
Nevertheless, you're correct, the setTabulators() will make any attempts to
calculate the size needed from the string itself pointless.
What you could do is calculate where the last tabulator is and then add the
length of the string that follows the last tab to it.
