I'm using Lazarus IDE v1.0.2 on Windows 7.

When I right click a button, I don't get an OnClick Event?

Is this expected? If so, why?

Seems we're faithfully following the competition/inspiration/other product: http://docwiki.embarcadero.com/Libraries/XE3/en/Vcl.StdCtrls.TButton.OnClick

.. that states the event fires for left mouse click, but nothing about right mouse click..

The competition/inspiration/other's doc says:

Use the OnClick event handler to respond when the user clicks the control. <<cut>>
Usually, OnClick occurs when the user presses and releases the left mouse button with the mouse pointer over the control. This event can also occur when: ...

So it doesn't outlaw OnClick for right click... :-)

Or could there be an OnRightClick event?

I have a Step button in a celluar automaton program, and hoped to have left click do one more line, right click to 10 more lines, and shift-click to 10 times the unshifted...

Now, in OnMouseDown, I have:
    if Button=mbRight then StepCount:=10 else StepCount:=1;
    if ssShift in Shift then StepCount:=10*StepCount;
Then in OnClick I use StepCount, but I have to doubleClick to get OnClick to fire....

Tested with Delphi 3. No OnClick on right-clicking.

Why is that? OnClick should fire with a single click.

Anyway you can use OnMouseUp to test Left/Right click. OnClick is not needed at all then.

Probably to avoid interference with any Menu defined for the Form. ?
