Gets a bitmask with the mouse buttons currently pressed, set to 1.

Since :

2.3.1

Remarks:

This function returns a 32-bit integer with the appropriate bits set to 1 that correspond to a mouse button being depressed. This limits Evas to mouse devices with a maximum of 32 buttons, but that is generally in excess of any host system's pointing device abilities.

The least significant bit corresponds to the first mouse button (button 1) and the most significant bit corresponds to the last mouse button (button 32).

If e is not a valid canvas, the return value is undefined.

The following is an example:

 extern Evas *evas;
 int button_mask, i;

 button_mask = evas_pointer_button_down_mask_get(evas);
 printf("Buttons currently pressed:\n");
 for (i = 0; i < 32; i++)
   {
     if ((button_mask & (1 << i)) != 0) printf("Button %i\n", i + 1);
   }

Parameters:

[in]

e

The pointer to the Evas canvas

Returns:

A bitmask of the currently depressed buttons on the canvas

Gets the current known pointer co-ordinates.

This function returns the current known canvas unit co-ordinates of the mouse pointer and sets the contents of the Evas_Coords pointed to by x and y to contain these co-ordinates. If e is not a valid canvas the results of this function are undefined.

Since :

2.3.1

Remarks:

The following is an example:

 extern Evas *evas;
 Evas_Coord mouse_x, mouse_y;

 evas_pointer_output_xy_get(evas, &mouse_x, &mouse_y);
 printf("Mouse is at canvas position %f, %f\n", mouse_x, mouse_y);

Parameters:

[in]	e	The pointer to the Evas Canvas
[out]	x	The pointer to a Evas_Coord to be filled in
[out]	y	The pointer to a Evas_Coord to be filled in

Checks whether the mouse pointer is logically inside the canvas.

Since :

2.3.1

Remarks:

When this function is called it returns a value of either 0 or 1.

A return value of 1 indicates the mouse is logically inside the canvas, and 0 implies it is logically outside the canvas.

A canvas begins with the mouse being assumed outside (0).

If e is not a valid canvas, the return value is undefined.

The following is an example:

 extern Evas *evas;

 if (evas_pointer_inside_get(evas)) printf("Mouse is in!\n");
 else printf("Mouse is out!\n");

Parameters:

[in]

e

The pointer to the Evas Canvas

Returns:

EINA_TRUE if the mouse is inside the canvas, otherwise EINA_FALSE

Gets the current known pointer co-ordinates.

This function returns the current known screen or output co-ordinates of the mouse pointer and sets the contents of the integers pointed to by x and y to contain these co-ordinates. If e is not a valid canvas the results of this function are undefined.

Since :

2.3.1

Remarks:

The following is an example:

 extern Evas *evas;
 int mouse_x, mouse_y;

 evas_pointer_output_xy_get(evas, &mouse_x, &mouse_y);
 printf("Mouse is at screen position %i, %i\n", mouse_x, mouse_y);

Parameters:

[in]	e	The pointer to the Evas Canvas
[out]	x	The pointer to an integer to be filled in
[out]	y	The pointer to an integer to be filled in
