Herror T_set_window_extents(const Htuple WindowHandle, const Htuple Row, const Htuple Column, const Htuple Width, const Htuple Height)

void SetWindowExtents(const HTuple& WindowHandle, const HTuple& Row, const HTuple& Column, const HTuple& Width, const HTuple& Height)

static void HOperatorSet.SetWindowExtents(HTuple windowHandle, HTuple row, HTuple column, HTuple width, HTuple height)

void HWindow.SetWindowExtents(int row, int column, int width, int height)

Description

set_window_extentsset_window_extentsSetWindowExtentsSetWindowExtentsSetWindowExtents positions the upper left corner of the output window at (RowRowRowRowrow,ColumnColumnColumnColumncolumn) and changes the size of the window to WidthWidthWidthWidthwidth and HeightHeightHeightHeightheight at the same time. Negative values for WidthWidthWidthWidthwidth and HeightHeightHeightHeightheight are ignored.

Attention

Modifying the size of the window does not automatically redraw the window contents. This has to be done by the program by redisplaying the desired data.
