Gdk::Rectangle
is a structure holding the position and size of a rectangle.
The intersection of two rectangles can be computed with
intersect()
. To find the union of two rectangles use
join()
.

bool Gdk::Rectangle::has_zero_area
|
(

)
|
const
|
Checks whether either the width or height is 0.
-
Returns
-
Whether this rectangle has 0 area.
Calculates the intersection of two rectangles, changing this rectangle.
If the rectangles do not intersect, this rectangle's width and height are set to 0 and its x and y values are undefined.
This method returns a reference to this instance, allowing you to then call another method easily. For instance: rect.intersect(src2).join(src3);
-
Parameters
-
src2
|
The rectangle with which to calculate the intersection with this rectangle.
|
-
Returns
-
A reference to this rectangle.

|
|
|
bool &
|
rectangles_intersect
|

)
|
|
|
Calculates the intersection of two rectangles, changing this rectangle.
If the rectangles do not intersect, this rectangle's width and height are set to 0 and its x and y values are undefined.
This method returns a reference to this instance, allowing you to then call another method easily. For instance: rect.intersect(src2, rectangles_intersect).join(src3);
-
Parameters
-
|
src2
|
The rectangle with which to calculate the intersection with this rectangle.
|
[out]
|
rectangles_intersect
|
This will be set to
true
if the rectangles intersect, else
false
.
|
-
Returns
-
A reference to this rectangle.
bool Gdk::Rectangle::intersects
|
(
|
const
Rectangle
&
|
src2
|
)
|
const
|
Checks whether two rectangles intersect.
-
Since gtkmm 3.8:
-
-
Parameters
-
src2
|
The rectangle with which to check intersection with this rectangle.
|
-
Returns
-
Whether this rectangle intersects
src2
.
Calculates the union of two rectangles, changing this rectangle.
The union of this rectangle and
src2
is the smallest rectangle which includes both this rectangle and
src2
within it.
This method returns a reference to this instance, allowing you to then call another method easily. For instance: rect.join(src2).intersect(src3);
-
Parameters
-
src2
|
The rectangle with which to calculate the union with this rectangle.
|
-
Returns
-
A reference to this rectangle.

Calculates the intersection of two rectangles.
If the rectangles do not intersect, the returned rectangle's width and height are set to 0 and its x and y values are undefined.
-
Since gtkmm 3.8:
-
-
Parameters
-
src1
|
One of the rectangles.
|
src2
|
The other rectangle.
|
-
Returns
-
The intersection of
src1
and
src2
.
Calculates the intersection of two rectangles.
If the rectangles do not intersect, the returned rectangle's width and height are set to 0 and its x and y values are undefined.
-
Since gtkmm 3.8:
-
-
Parameters
-
|
src1
|
One of the rectangles.
|
|
src2
|
The other rectangle.
|
[out]
|
rectangles_intersect
|
This will be set to
true
if the rectangles intersect, else
false
.
|
-
Returns
-
The intersection of
src1
and
src2
.
Calculates the union of two rectangles.
The union of
src1
and
src2
is the smallest rectangle which includes both
src1
and
src2
within it.
-
Since gtkmm 3.8:
-
-
Parameters

The union of
src1
and
src2
.
-
Parameters
-
-
Returns
-
A C++ instance that wraps this C instance.
-
Parameters
