I have a spreed sheet (include a table of input boxes in the out put) I put a scroll bar for it as it was larger than the screen width I did this by using Fl_Scroll and made the input boxes between Fl_Scroll scroll = new Fl_Scroll(0, 0, 780, 580); **** scroll->end(); I wanted to add labels rows and columns but something that is important is that the labels of rows should just scroll by the vertical scroll bar and the labels of columns should just scroll by the horizontal scroll bar and I dont know how should I do this? how can I understand which scroll bars( horizontal or vertical) was selected and how should I write my scroll call back? (I insist on using Fl_Scroll not Fl_Scrollbar) another question is how should I open a saved spreed sheet? I saved it and restore it using files but the new spreed sheet I open is not editable and the last I don't know why I can one time I run the program draw a chart and next time I try to I encounter with an empty page, should I add something else to my program or the problem is something else?
