[Openroad-users] Displaying Image in optionfield

[Bloomfield, Martin (PSD)]

Thanks for all your replies.  It confirmed my suspicion that you can add
bitmaps to choicelists, but cannot view them.  I have reverted to
copying the bitmaps from a hidden palette field into a bitmapobject
attribute of my userclass.  I did, however, discover that the tablefield
attribute containing the bitmap also has to exist in the userclass
otherwise it does not get displayed and openROAD crashes (there are no
compilation errors however).

Martin,

 

All choice lists have enumbitmap (as part of the ChoiceDetail class), at
least since version 4.0, but only palettefields display them;
ListViewFields by contrast display images from a smallimagelist and
largeimagelist, both of which are array of bitmapobject.  I tend to use
the palettefield editor to load my lookup images + keyword (the editor
puts them in the tooltiptext); then in the startup code I loop through
to copy the keyword to the enumtext so I can subsequently use
valuelist.BitmapByText().  

 

Regards,

Sean.

Martin,

 

Am I right in presuming that the optionfield is used to decode the
values and isn't shown to the user in the tablefield?

 

If so, instead of holding the code/decode values in an optionfield could
you use a ListViewField? The ListViewField uses a choicelist that is
composed of ChoiceBitmap objects, each of which has an enumvalue,
enumtext and an enumbitmap.

 

Hope that helps.

 

Regards,

Jim

	In my latest project I have a class which contains a single
character attribute to indicate whether a phrase has been Accepted,
Rejected or is Pending Acceptance.  Rather than displaying this as text
in a tablefield, I would like to display a bitmap (Tick, Cross, Question
mark).  If I was displaying the text, I would use an optionfield to
decode the single character into the required text.  

	I though it was possible to do the same thing with a bitmap.
However, I cannot seem to find how to load and display a bitmap in an
optionfield.  Is this possible, or am I going to have to add code to
copy the image from a (hidden) palette of images into an imagetrim in
the tablefield based on the character code?

	Thanks,

	Martin Bloomfield.
