adjustxy(RECTANGLE

, BOUNDARY

, DELTAV

, DELTAH

)
The** adjustxy( **function adjusts the four corners of a rectangle. However, only corners
that are inside a boundary are adjusted. Corners outside the boundary are left alone.

**Parameters**

This function has four parameters:

** rectangle** – is the rectangle that is being adjusted.

** boundary** – is a rectangle describing the area to be adjusted. Only points inside this rectangle will be adjusted.

** deltav** – is the vertical distance each corner inside the boundary should be adjusted.

** deltah** – is the horizontal distance each corner inside the boundary should be adjusted.

**Description**

The procedure below uses adjustxy to help move a slider on a form. This procedure is designed to be triggered by a button with the Click/Release option turned off.

```
local drag,dragstart,deltaV,deltaH,slider,slidebox
drag=info("buttonrectangle")
dragstart=drag
slider=xytoxy(drag,"s","f")
slider=rectangleadjust(slider,0,0,1,1)
selectobjects intersectionrectangle(xytoxy(drag,"s","f"),
objectinfo("rectangle") <> rectangle(0,0,0,0))
slidebox=xytoxy( objectinfo("boundary"),"f","s")
slidebox=rectangleadjust(insidewindow,0,16,0,-16)
draggraybox drag,slidebox,info("windowrectangle"),1
if drag="" stop endif
deltaV=rtop(drag)-rtop(dragstart)
deltaH=rleft(drag)-rleft(dragstart)

```
