Wimp question

[Stefan Bellon]

Hi!

Currently I'm displaying a JPEG in a simple window which works very
well. But on a mode change that modifies the xeig and/or yeig values,
the window is double or half the size in any or both directions.

Therefore whenever I get message_MODE_CHANGE I do the following:

  wimp_close_window(mainwin);
  wopen->visible.x1 = wopen->visible.x0 + (1 << xeig) * width;
  wopen->visible.y1 = wopen->visible.y0 + (1 << yeig) * height;
  extent.x0 = 0;
  extent.y0 = 0;
  extent.x1 = (1 << xeig) * width;
  extent.y1 = (1 << yeig) * height;
  wimp_set_extent(mainwin, &extent);
  wimp_open_window(wopen);

Where mainwin is the handle of the window (type wimp_w), extent is of
type os_box and wopen is a pointer to a wimp_open structure.

What am I missing?

TIA.

Greetings,

Stefan.
