NAME

Document::Open - instance method

TEMPLATE

newDocOpened = bool Open()

SPECIFIERS

public virtual

DESCRIPTION

Open first checks what to do with unsaved changes (see method AlertChanges). Then it opens the load file dialog. When the user selects a file the method CanLoadDocument checks whether it can be loaded. If this is the case the file is loaded by the method Load. If the method CanLoadDocument returns FALSE, then a new document is created by passing the name of the file to the method Application::OpenDocument. Method is rarely overridden.

ARGUMENTS

none

RETURN ARGUMENT

bool newDocOpened: It is TRUE if a new document has actually been opened. It is FALSE if the user cancelled the operation, did not select a file or storing unsaved changes by the method Save failed.

FIRST DEFINITION

class Document

FILES

implementation:: Document.C

KNOWN PROBLEMS

The command gResetUndo is performed in any case; but it may only be performed after another file has successfully been loaded. The statement Load(...) should be changed to if (Load(...)) PerformCommand(gResetUndo); or Load itself should execute gResetUndo. See also method Load.
