Arguments

Function result

Dialog class instance created in the method.

Description

CreateDialog is a TCommonDialog function which creates and returns the dialog for the grouped edit control.

AKind contains the TDialogKind value that identifies the dialog type required for the control, and normally has the value from the DialogKind property. AKind determines the class type instantiated and used as the return value. For example:

dkOpen

TOpenDialog is the type in return value.

dkPictureOpen

TOpenPictureDialog is the type in return value.

dkSave, dkPictureSave

TSaveDialog is the type in return value.

Properties relevant to the dialog kind are copied into the dialog, and may include:

• FileName
• Path information extracted from FileName
• InitialDir
• DefaultExt
• Filter
• FilterIndex
• DialogOptions
• DialogTitle

For an open dialog, path information in FileName is retained if the path is valid. This causes use of InitialDir to be disabled in the dialog. If the path in Filename is invalid, only the base file name and extension are copied to the dialog. An explicit value in InitialDir is resolved (cleaned and expanded) when valid, and stored to the dialog. Otherwise, the initial directory is determined by the widgetset when the dialog is executed.

CreateDialog is used in the implementation of the RunDialog method.
