Constructor & Destructor Documentation

◆ TLvColumn() [1/5]

owl::TLvColumn::TLvColumn	(	uint	mask_ = lvcfAll,
		int	subitemIndex = 0,
		int	bufferSize = 1000 )

explicit

Constructs an empty parameter package.

This constructor is typically used to retrieve information about an existing column. For example,

TLvColumn col;
bool success = ListWnd.GetColumn(1, col);
if (success && col.GetText()) ShowString(col.GetText());

Parameters

[in]	mask_	is the mask to use.
[in]	subitemIndex	is the subitem index to use.
[in]	bufferSize	is the size of the text characters to allocate and use, provided the mask includes LVCF_TEXT.

◆ TLvColumn() [2/5]

owl::TLvColumn::TLvColumn	(	const tstring &	text,
		int	width,
		TFormat	how = Left,
		int	subitemIndex = 0 )

Constructs a parameter package based on the given text, width, format, and subitem.

Parameters

[in]	text	is the string to use.
[in]	width	is the pixel width to use the column; if 0, a width will be calculated by SetWidth.
[in]	how	specifies the formatting to use for the string.
[in]	subitemIndex	is the subitem index to use.

Definition at line 586 of file listviewctrl.cpp.

		int	index,
		uint	mask_ = lvcfAll,
		int	subitemIndex = 0,
		int	bufferSize = 1000 )

Constructs a parameter package based on the column attributes of an existing control.

Parameters

[in]	ctl	is an existing list-view control from which to copy.
