const ErrorMessageData &

data

ScheduleErrorMessage() [2/2]

void ScheduleErrorMessage

(

ErrorList &

datas

Schedule a list of errors.

Note: This does not try to display the error now. This is useful if the window system is not yet running.

Parameters

datas

Error message datas; cleared afterwards

ShowErrorMessage() [1/2]

void ShowErrorMessage	(	EncodedString &&	summary_msg,
		EncodedString &&	detailed_msg,
		WarningLevel	wl,
		int	x,
		int	y,
		EncodedString &&	extra_msg,
		CompanyID	company
	)

Display an error message in a window.

Parameters

summary_msg	General error message showed in first line. Must be valid.
detailed_msg	Detailed error message showed in second line. Can be empty.
wl	Message severity.
x	World X position (TileVirtX) of the error location. Set both x and y to 0 to just center the message when there is no related error tile.
y	World Y position (TileVirtY) of the error location. Set both x and y to 0 to just center the message when there is no related error tile.
extra_msg	Extra error message shown in third line. Can be empty.

ShowErrorMessage() [2/2]

void ShowErrorMessage	(	EncodedString &&	summary_msg,
		int	x,
		int	y,
		CommandCost &	cc
	)

Display an error message in a window.

Note: CommandCost errors are always severity level WL_INFO.

Parameters

summary_msg	General error message showed in first line. Must be valid.
x	World X position (TileVirtX) of the error location. Set both x and y to 0 to just center the message when there is no related error tile.
y	World Y position (TileVirtY) of the error location. Set both x and y to 0 to just center the message when there is no related error tile.
cc	CommandCost containing the optional detailed and extra error messages shown in the second and third lines (can be empty).
