- set_size(x, y,width,height)
lets you to set position and size of an object
- set_size(width,height)
lets you to set size of an object
- set_position(x,y)
lets you to set position of an object
- set_x(x)
lets you to set the horizontal position of an object
- set_y(y)
lets you to set the vertical position of an object
- set_width(width)
see set_size()
- set_height(height)
see set_size()
- x()
returns the x co-ordinate of the object
- y()
returns the y co-ordinate of the object
- width()
returns the width of the object
- height()
returns the height of the object
- key()
returns a object of type hk_key. You can use this during the action_on_key() action. In combination with the hk_keys 'set_accept_key()' method you can handle whether or not this key will be accepted as input.

triggers the on_open action
- action_on_getfocus(void)
triggers the on_getfocus action
- action_on_loosefocus(void)
triggers the on_loosefocus action
- action_on_key(void)
triggers the on_key action
Figure 2-8. Look and Feel methods

Example 2-13. Changing colour and position
redcolour =hk_colour(255,0,0) greencolour =hk_colour(0,255,0) if hk_this.foregroundcolour().red()!=255: hk_this.set_foregroundcolour(redcolour) hk_this.set_backgroundcolour(greencolour) hk_this.set_label("green button") else: hk_this.set_foregroundcolour(greencolour) hk_this.set_backgroundcolour(redcolour) hk_this.set_label("red button") hk_this.set_position(hk_this.x()+50,hk_this.y()+10)
