Hello!
I have a series of pictures, dropped in the project window so they are
known to the app.
I have a dictionary containing pairs of strings, the seconds being the
_names_ of the aforesaid pictures.
I want to assign these pictures to canvases, according to dictionary
searches. I know how to retrieve correctly the _names_ of the desired
pictures, but how do I tell the app that I want it to load the
_pictures_ ? In another way, I would like to be able to write
something like :
thiscanvas.backdrop = Picture(thisname)
Maybe defining the dictionary a different way, maybe through some
coercing method, I am lost in the wilderness...
Define a global Dictionary object PictureMap. Load this Dictionary at
runtime --
For each PictureName
PictureMap.Value("PictureName") = Picture
Next
Alternatively, move the pictures to a directory, and load them from
disk at runtime. You could write a function like the following.
Function LoadPicture(pictureName as String) as Picture
If PictureDirectory <> nil and PictureDirectory.Child(pictureName) <>
Nil then
Return PictureDIrectory.Child(pictureName).OpenAsPicture
Else
Return nil
End if
End Function
Inside this function you could add the ability to cache Picture objects
once open.
