SELECTING PRIMITIVES
CRIMSON USER MANUAL - MODULAR CONTROLLER
SELECTING PRIMITIVES
To select a display primitive, simply move your mouse pointer over the primitive in question,
and perform a left-click. You will notice that while your pointer is hovering over a primitive,
a bounding rectangle is drawn in blue to help show what will be selected. When the actual
selection is performed, the rectangle will change to red, and handles will appear, so as to
allow you to re-size the primitive as required. If you find that the primitive you want to select
is hidden below another primitive, press the Alt key to allow the selection to be made.
To select several primitives, either drag-out a selection rectangle around the primitives you
want to select, or select each primitive in turn, holding down the Shift key to indicate that
you want each primitive to be added to the selection. If multiple primitives are selected, the
red rectangle will surround all of the primitives, and the handles can then be used to resize the
primitives as a group. The relative size and position of the primitives will be maintained, as
long as Crimson can do so without violating minimum size requirements.
MOVING AND RESIZING
Primitives can be moved by first selecting them, and then by dragging them to the required
position on the display page. If Smart Align is turned on, guidelines will appear to help you
align the primitives with other items on the page. Holding down Ctrl while moving a
primitive will leave a copy of the primitive in its original position, thereby allowing
duplicates to be created. You can also use the cursor keys to “nudge” the current selection a
single pixel in the required direction. Holding down Ctrl while nudging will increase the
movement of the primitives by a factor of eight.
Primitives can be resized by selecting them, and then by dragging the appropriate handle to
the required position. Once again, if Smart Align is turned on, guidelines will appear to help
you align the primitives with other items on the page. The Shift and Ctrl keys can be used
to modify the resize behavior as described in the Adding Display Primitives section. Note that
Crimson will always constrain resizing operations so as to ensure that primitives stay on the
screen, and to make sure that items do not exceed their maximum permitted size, or shrink
below the minimum size appropriate to their format.
