Continuing with this example, if you change the Name property of the edit control from
MyEdit to FirstName, C++Builder will change the pointer name to FirstName and the
OnChange handler name to FirstNameChange(). It’s all done automatically; you don’t have to
do anything but change the Name property and trust that C++Builder will do its thing.
WARNING
NOTE
Never change the Name property at runtime. Never manually change a
component’s name (the name that C++Builder assigned to the
component’s pointer) or event handler names in the Code Editor. If
you do either of these, C++Builder loses track of components, and the
results are not good, to say the least. You might even lose the ability to
load your form. The only safe way to change the Name property of a
component is through the Object Inspector.
C++Builder assigns a default value to the Name property for all components placed on a form.
If you place an Edit component, for example, C++Builder assigns Edit1 to the Name property.
If you place a second Edit component on the form, C++Builder assigns Edit2 to that
component’s Name property, and so on. You should give your components meaningful names
as soon as possible to avoid confusion and extra work later on.
You can leave the default names for components that will never be
referenced in code. For example, if you have several label components
that contain static (unchanging) text, you can leave the default names
because you won’t be accessing the components at runtime.
HOUSE RULES: THE Name PROPERTY
■ Change the Name property of a component from the default name to a meaningful
name as soon as possible.
■ Components not referenced at runtime can be left with the C++Buildersupplied
name.
■ Never change the Name property of a component in code or at runtime.
■ Make your components’ names meaningful but not overly long.
