Description
TMsgDlgType defines values describing the type of message box.
The TMsgDlgType type defines the values describing the type of a message box. TMsgDlgType is used by the MessageDlg and MessageDlgPos functions.
The following table lists the possible values:
| Value | Meaning |
|---|---|
|
|
A message box containing a yellow exclamation point symbol. |
|
|
A message box containing a red stop sign. |
|
|
A message box containing a blue "i". |
|
|
A message box containing a blue "i". See the footnote. |
|
|
A message box containing no bitmap. The caption of the message box is the name of the application's executable file. |
Note::
Since RAD Studio XE6 the mtConfirmation symbol has changed from a blue question mark to a blue "i".
Microsoft removed the question mark symbol from the function that RAD Studio uses to display the message. Quoting Microsoft: "The question-mark message icon is no longer recommended because it does not clearly represent a specific type of message and because the phrasing of a message as a question could apply to any message type. In addition, users can confuse the message symbol question mark with Help information."
There is a workaround to use the previous message box, set the UseLatestCommonDialogs var from Vcl.Dialogs to False.
procedure TForm1.Button1Click(Sender: TObject);
begin
UseLatestCommonDialogs := False;
MessageDlg('Foo', mtCustom, [mbOk], 0);
end;
