[Iup-users] IUP matrix with a scrollbar

[Steven Mak]

Hi all,

I am writing an application using IUP matrix control. Here's how it is created:


  Ihandle *_mat;
  _mat = IupMatrix("myaction");
  IupSetAttributes(_mat,"SCROLLBAR=YES DX=0.5 DY=0.5");
  IupSetAttribute(_mat,IUP_VERTICAL,"YES");
  IupSetAttribute(_mat,IUP_HORIZONTAL,"YES");
  IupSetAttribute(_mat,IUP_RESIZEMATRIX,"YES");
  IupSetAttribute(_mat,IUP_NUMCOL,"2"); 
  IupSetAttribute(_mat,IUP_NUMLIN,"16"); 
  
  IupSetAttribute(_mat,IUP_NUMCOL_VISIBLE,"2") ;
  IupSetAttribute(_mat,IUP_NUMLIN_VISIBLE,"0") ;
  
  IupSetAttribute(_mat,"0:0","Inflation");
  IupSetAttribute(_mat,"1:0","Medicine");
  IupSetAttribute(_mat,"2:0","Food"); 
  IupSetAttribute(_mat,"3:0","Energy"); 
  IupSetAttribute(_mat,"0:1","January 2000"); 
  IupSetAttribute(_mat,"0:2","February 2000"); 
  IupSetAttribute(_mat,"1:1","5.6");
  IupSetAttribute(_mat,"2:1","2.2");
  IupSetAttribute(_mat,"3:1","7.2");
  IupSetAttribute(_mat,"4:1","7.2");
  IupSetAttribute(_mat,"5:1","7.2");
  IupSetAttribute(_mat,"6:1","7.2");
  IupSetAttribute(_mat,"7:1","7.2");
  IupSetAttribute(_mat,"8:1","7.2");
  IupSetAttribute(_mat,"9:1","7.2");
  IupSetAttribute(_mat,"10:1","7.2");
  IupSetAttribute(_mat,"11:1","7.2");
  IupSetAttribute(_mat,"12:1","7.2");
  IupSetAttribute(_mat,"13:1","7.2");
  IupSetAttribute(_mat,"14:1","7.2");
  IupSetAttribute(_mat,"15:1","7.2");
  IupSetAttribute(_mat,"1:2","4.5");
  IupSetAttribute(_mat,"2:2","8.1");
  IupSetAttribute(_mat,"3:2","3.4");
  IupSetAttribute(_mat,"4:2","3.4");
  IupSetAttribute(_mat,"5:2","3.4");
  IupSetAttribute(_mat,"6:2","3.4");
  IupSetAttribute(_mat,"7:2","3.4");
  IupSetAttribute(_mat,"8:2","3.4");
  IupSetAttribute(_mat,"9:2","3.4");
  IupSetAttribute(_mat,"10:2","3.4");
  IupSetAttribute(_mat,"11:2","4.4");
  IupSetAttribute(_mat,"12:2","4.4");
  IupSetAttribute(_mat,"13:2","4.4");
  IupSetAttribute(_mat,"14:2","4.4");
  IupSetAttribute(_mat,"15:2","4.4");
  IupSetAttribute(_mat,"WIDTHDEF","34");

  IupSetAttribute(_mat,IUP_CURSOR,"ARROW");

It compiled successfully. However, the window only show upper potion of the matrix, first 12 lines. I press down arrow key in order to show the bottom rows. There is no scoll bar indicated.

I am wondering if I can have a vertical scrollbar so as to scroll down with a mouse. In fact, you can see that I have attempted to enable scrollbar. However, it wasn't shown up.

Can I know if there is anything I am wrong here? or do you have any example code for a matrix with a scrollbar.

Thank you very much,
Steven
