tool bar drop-down creation..?

The goal:
to have a pulldown "menu" of page setups 24x36, 11x17, 8.5x11.. and
beside that.. have a "changing" text readout.. for text size (that will
change depending on what dimstyle is current).

how would I go about doing this?

for an example of the pull-down I'm after, just look at the "dimension"
toolbar.. the dimstyle pulldown


TIA

 

addition:

The pagesetup pull down will NOT effect the drawing as a whole.. it will
only effect the text size readout (different text sizes for each paper
size.. and scale)

 

Can you give me any pointers?.. (I posted in the ARX, but that NG seems
rather dead so I could be waiting a while).

 

Joy.

 

<chuckle>..... I know absolutely nothing about ARX, other
than is seems difficult and you need a couple of years of
C++ programming first, or so I have read.

 

we have found another solution.. scrapped the whole tool bar idea, and
opted to a alert box. lisp looks at the current dim style text hight,
multiplies that by the dim scale, and spits out the correct text height
for that scale.

Simple is good.
