Detailed Description

Container to store values used in container related methods.

uiTableValue objects are immutable.

uiTable and uiTableModel methods take ownership of the uiTableValue objects when passed as parameter. Exception: uiNewTableValueImage().

uiTable and uiTableModel methods retain ownership when returning uiTableValue objects. Exception: uiTableValueImage().

Member Function Documentation

uiFreeTableValue()

void uiFreeTableValue

(

uiTableValue *

v

)

Frees the uiTableValue.

Parameters

v	Table value to free.

Warning

This function is to be used only on uiTableValue objects that have NOT been passed to uiTable or uiTableModel - as these take ownership of the object.
Use this for freeing erroneously created values or when directly calling uiTableModelHandler without transferring ownership to uiTable or uiTableModel.

uiNewTableValueColor()

uiTableValue * uiNewTableValueColor	(	double	r,
		double	g,
		double	b,
		double	a
	)

Creates a new table value to store a color in.

Parameters

r	Red. Double in range of [0, 1.0].
g	Green. Double in range of [0, 1.0].
b	Blue. Double in range of [0, 1.0].
a	Alpha. Double in range of [0, 1.0].

Returns

A new uiTableValue instance.

uiNewTableValueImage()

uiTableValue * uiNewTableValueImage

(

uiImage *

img

)

Creates a new table value to store an image.

Parameters

img	Image. Data is NOT copied and needs to kept alive.

Returns

A new uiTableValue instance.

Warning

Unlike other uiTableValue constructors, uiNewTableValueImage() does NOT copy the image to save time and space. Make sure the image data stays valid while in use by the library. As a general rule: if the constructor is called via the uiTableModelHandler, the image is safe to free once execution returns to ANY of your code.

uiNewTableValueInt()

uiTableValue * uiNewTableValueInt

(

int

i

)

Creates a new table value to store an integer.

This value type can be used in conjunction with properties like column editable [TRUE, FALSE] or controls like progress bars and checkboxes. For these, consult uiProgressBar and uiCheckbox for the allowed integer ranges.

Parameters

i	Integer value.

Returns

A new uiTableValue instance.

uiNewTableValueString()

uiTableValue * uiNewTableValueString

(

const char *

str

)

Creates a new table value to store a text string.

Parameters

str	String value. A valid, NUL terminated UTF-8 string. Data is copied internally. Ownership is not transferred.

Returns

A new uiTableValue instance.

uiTableValueColor()

void uiTableValueColor	(	const uiTableValue *	v,
		double *	r,
		double *	g,
		double *	b,
		double *	a
	)

Returns the color value held internally.

To be used only on uiTableValue objects of type uiTableValueTypeColor.

Parameters

	v	Table value.
[out]	r	Red. Double in range of [0, 1.0].
[out]	g	Green. Double in range of [0, 1.0].
[out]	b	Blue. Double in range of [0, 1.0].
[out]	a	Alpha. Double in range of [0, 1.0].

uiTableValueGetType()

uiTableValueType uiTableValueGetType

(

const uiTableValue *

v

)

Gets the uiTableValue type.

Parameters

v	Table value.

Returns

Table value type.

uiTableValueImage()

uiImage * uiTableValueImage

(

const uiTableValue *

v

)

Returns a reference to the image contained.

To be used only on uiTableValue objects of type uiTableValueTypeImage.

Parameters

v	Table value.

Returns

Image.
Data is owned by the caller of uiNewTableValueImage().

Warning

The image returned is not owned by the object v, hence no lifetime guarantees can be made.

uiTableValueInt()

int uiTableValueInt

(

const uiTableValue *

v

)

Returns the integer value held internally.

To be used only on uiTableValue objects of type uiTableValueTypeInt.

Parameters

v	Table value.

Returns

Integer value.

uiTableValueString()

const char * uiTableValueString

(

const uiTableValue *

v

)

Returns the string value held internally.

To be used only on uiTableValue objects of type uiTableValueTypeString.

Parameters

v	Table value.

Returns

String value.
A NUL terminated UTF-8 string.
Data remains owned by v, do NOT call uiFreeText().
