Dear all,
I am trying to find out the width of a text string and write it on the
middle of the screen using .
I have tried
GR_SIZE text_width; /* variable to store text width of normal
text */
GR_SIZE text_height; /* variable to store text height of normal
text */
GR_SIZE text_base; /* variable to store text baselineheight of
normal text */
GrGetGCTextSize( gc , "A" , 1 , (int)NULL , text_width , text_height ,
text_base );
GrText(wid , gc , 400 - ((int)text_width_n * 7) , 240 , "books
selected", 14 , (int)NULL ); // on a 800 X 480 display
But the text does not appear exactly where I want it to be printed.
I tried to use other APIs like GrGetFontInfo , but was a little confused by
the pointer to GR_FONT_INFO structure used in it.
I tried to find information about the structure on the net.
It said that it is defined in graphics.h in /usr/src.
As I could not find graphics.h in my /usr/src directory , I have no
information about the structure.
Am I missing something here ?
Please help in resolving this problem by giving pointers to the solution.
Also it would be a great help for me if someone could refer some pointers
for me to find information about the GR_FONT_INFO structure.
Thanks and regards.
