mseedit

Declaration

type tcustomedit = class(tpublishedwidget, iedit)

Description

This item has no description. Showing description inherited from tmsecomponent.

Extends the FPC tcomponent with object linking facilities and the like; base of every MSEgui component. This unit, mseclasses, must be added to uses after classes in code that also uses a third-party unit expecting the plain FPC tcomponent (e.g. TPSScript.Create(TComponent)), since MSEgui forks the FPC classes unit.

Public property text: msestring read gettext write settext;

The data-edit widgets (tintegeredit, tstringedit, trealedit...) keep their data in value, of the widget's native type. text is the raw, not yet validated text of the embedded inplace editor, updated on every keystroke; it is converted to value by checkvalue (triggered for example by pressing Enter), which can be intercepted and rejected or modified through the onsetvalue/oncheckvalue events — ondataentered fires afterwards, once the new value has actually been accepted. To set a widget's value from code, assign value, not text: the latter is only meant to reflect (or drive) what the user is currently typing.
