In-Depth Information
The icons also serve as convenient shortcuts for managing your breakpoints.
Clicking the icon removes the breakpoint. Successive use of
Alt+Click
the icon
toggles its state between enabled and disabled. Right-clicking the breakpoint icon
provides a context menu with three options:
Disable
(like
Alt+Click
) temporarily disables the breakpoint.
■
Remove
permanently removes the breakpoint.
■
Properties
lets you configure the breakpoint in the
Breakpoints
panel.

Table 6.1 The editor displays the status of your breakpoints in the left gutter. The icons allow you to
immediately tell the type and status of the breakpoint without requiring a visit to the Breakpoints
configuration window.

Runtime breakpoints
When you run the debugger, it prepares and evaluates the configured break-
points. When this happens, the breakpoint becomes either
verified
or
invalid
, and
the icon in the gutter area updates to reflect this state. If the breakpoint is refused
and becomes invalid, in most cases it means there was an absence of debugging
