Message Boxes

Message boxes in U++ provide up to 3 buttons. The message is using QTF rich text format - it means that you can for example embed hyper-link or even table or image. This however can cause issues if some non-literal text is presented which can accidentally contain QTF formatting characters. To solve this, you can use DeQtf function '\1' switch (supresses QTF parsing till the next '\1'), e.g.:

PromptOK(DeQtf("C:\\Program Files\\Upp\\theide"));

PromptOK("\1C:\\Program Files\\Upp\\theide");

There are many various functions providing message boxes. The first word in camel case function name designates the icon used in the message box and possible associated sound. It is followed by the name of buttons and optional Opt or Opt1 part. Opt and Opt1 mean that the dialog has "Do not show this again" option (more on that later).

If there are 2 or 3 buttons, the function returns an int to report which button was pressed. First button listed in the name returns 1, second 0 and third -1 (e.g. in PromptYesNo Yes is 1 and No is 0, in PromptYesNoCancle Yes is 1, No is 0 and Cancel is -1).

If the name contains Opt or Opt1, the process of ignoring the dialog next time is automated via storing specific String key - this key is passed as second const char * parameter to the function - if it is NULL (default), it is generated by hashing the message.

The diference between Opt and Opt1 is that Opt remembers which button was pressed and returns the same value next time (e.g. if in PromptOKCancel "Do not show again" is checked and user presses Cancel, the next the same PromptOKCancel is invoked, it returns without displaying the dialog with 0). As this behaviour can be confusing in certain context, Opt1 variant only grants "Do not show again" request if the user chooses button that returns 1 (e.g. OK or Yes).



void ClearPromptOptHistory()

Clears the list of "Do not show again" message boxes.



void ClearPromptOptHistory(Gate<Stringfilter)

Clears the list of "Do not show again" message boxes - only removes those where filter returns true for opt_id.



void SerializePromptOptHistory(Stream& s)

Serializes the list of "Do not show again" message boxes.



void RedirectPrompts(RedirectPromptFn r)

Completely redirects all message boxes to another function.
