◆ Draw()

uint BaseSettingEntry::Draw	(	GameSettings *	settings_ptr,
		int	left,
		int	right,
		int	y,
		uint	first_row,
		uint	max_row,
		BaseSettingEntry *	selected,
		uint	cur_row = `0`,
		uint	parent_last = `0`
	)		const

virtual

Draw a row in the settings panel.

The scrollbar uses rows of the page, while the page data structure is a tree of SettingsPage and SettingEntry objects. As a result, the drawing routing traverses the tree from top to bottom, counting rows in cur_row until it reaches first_row. Then it enables drawing rows while traversing until max_row is reached, at which point drawing is terminated.

The parent_last parameter ensures that the vertical lines at the left are only drawn when another entry follows, that it prevents output like

*  |-- setting
*  |-- (-) - Title
*  |    |-- setting
*  |    |-- setting
*

The left-most vertical line is not wanted. It is prevented by setting the appropriate bit in the parent_last parameter.

Parameters

settings_ptr	Pointer to current values of all settings
left	Left-most position in window/panel to start drawing first_row
right	Right-most x position to draw strings at.
y	Upper-most position in window/panel to start drawing first_row
first_row	First row number to draw
max_row	Row-number to stop drawing (the row-number of the row below the last row to draw)
selected	Selected entry by the user.
cur_row	Current row number (internal variable)
parent_last	Last-field booleans of parent page level (page level i sets bit i to 1 if it is its last field)

Returns: Row number of the next row to draw

◆ IsFiltered()

bool BaseSettingEntry::IsFiltered ( ) const

inline

Check whether an entry is hidden due to filters.

Returns: true if hidden.

◆ IsVisible()

bool BaseSettingEntry::IsVisible ( const BaseSettingEntry * item ) const

virtual

Check whether an entry is visible and not folded or filtered away.

Note: This does not consider the scrolling range; it might still require scrolling to make the setting really visible.

Parameters

item	Entry to search for.

Returns: true if entry is visible.

Set whether this is the last visible entry of the parent node.

Parameters
