draw_rectangle2_modT_draw_rectangle2_modDrawRectangle2ModDrawRectangle2Mod — Interactive drawing of any orientated rectangle.


draw_rectangle2_mod( : : WindowHandle, RowIn, ColumnIn, PhiIn, Length1In, Length2In : Row, Column, Phi, Length1, Length2)

Herror T_draw_rectangle2_mod(const Htuple WindowHandle, const Htuple RowIn, const Htuple ColumnIn, const Htuple PhiIn, const Htuple Length1In, const Htuple Length2In, Htuple* Row, Htuple* Column, Htuple* Phi, Htuple* Length1, Htuple* Length2)

draw_rectangle2_moddraw_rectangle2_modDrawRectangle2ModDrawRectangle2ModDrawRectangle2Mod returns the parameter for any orientated rectangle, which has been created interactively by the user in the window.

The created rectangle is described by its center, its two half axes and the angle between the first half axis and the horizontal coordinate axis.

To create a rectangle are expected the parameters RowInRowInRowInRowInrowIn, ColumnInColumnInColumnInColumnIncolumnIn,PhiInPhiInPhiInPhiInphiIn,Length1InLength1InLength1InLength1Inlength1In,Length2InLength2InLength2InLength2Inlength2In. A click close to one side “grips” it to modify the rectangle's dimension in perpendicular direction (Length2Length2Length2Length2length2) to this side. You only can modify the orientation (PhiPhiPhiPhiphi), if you grip a side perpendicular to the first half axis. After another mouse click in the middle of the created rectangle, you can move it. Pressing the right mouse button terminates the procedure. On macOS draw_rectangle2_moddraw_rectangle2_modDrawRectangle2ModDrawRectangle2ModDrawRectangle2Mod can also be terminated by pressing the escape key.

After terminating the procedure the rectangle is not visible in the window any longer.


If used in a buffer window, mouse events have to be supplied by the application, while the draw operator must be run in another thread.

draw_rectangle2_moddraw_rectangle2_modDrawRectangle2ModDrawRectangle2ModDrawRectangle2Mod returns 2 (H_MSG_TRUE), if the window is valid and the needed drawing mode (see set_insertset_insertSetInsertSetInsertSetInsert) is available. If necessary, an exception is raised.
