Hiding report components in end-user designer

rbuser

Hi,

We use 1 central tppVariable for all calculations that has to be done on a
ging pipeline. But when the user deletes the variable from its report, all
calcs dissapear too making the report unusable. Further more he can't hook
it back up because the code resides in the delphi form... Isn't there a way
to hide certain report components or set them read only/non changeable/non
deletable.

Greetings,
Filip Moons

Here is an example of preventing the end-user from selecting a specified
component...

Nice thx Nard, any way to take it one step further and completely hide it
from the designer. The end-user still can change settings for 'non
selectable' components by right clicking. Especially the 'Timing' entry in
the popup menu for variables i would prefer to be hidden or non accessable.

Greetings,
Filip Moons.

There is nothing built into the product that enables components to be hidden
from the end-user. That would be a nice feature to add to a future release
(also the ability to lock components from being moved by the end-user).

The TppDesignerWindow class (see ppDsgner.pas) has a private, internal
DesignControlManager class that it uses to gain access to the DesignControl
associated with a Component. (For example a TppVariable will have an
associated DesignControl that is used by the designer. So you might be able
to modify the source code of TppDesignerWindows to set the
DesignControl.Visible property to False.
