Forms: using the LAF to display Google Charts

One of the features of the Look and Feel Project, is the capability to add items at runtime, and more particularly Image items, via the IMG_NEW method. As Google Charts are PNG images, it is easy to use a dynamic image to display them.

Only 3 instructions are required:

Declare
  LC$Chart Varchar2(2000) := 'http://chart.apis.google.com/chart?cht=v&chs=200x100&chd=t:100,80,60,30,25,20,10';
Begin  
  -- add image to the canvas --
  Set_Custom_Property('LAF_BLOCK.LAF_BEAN',1,'IMG_NEW','img,10,80,450,230');
  Set_Custom_Property('LAF_BLOCK.LAF_BEAN',1,'IMG_SET_BORDER','img,line' ) ;
  -- populate image --
  Set_Custom_Property('LAF_BLOCK.LAF_BEAN',1,'IMG_READIMGFILE'
                     ,'img,' || replace(LC$Chart,',','%2C'));
End;

That's all !

I have added a new test_laf_gchart.fmb sample dialog in the current LAF_1772.zip if you want to play with.
