getpos_self

uiz_getposx/y_self

Gets a value using getposx/y but uses it's own object as a reference instead of it's parent. uiz_getposx_self(1,fc) will give the objects width and uiz_getposx_self(0.5,fc) half of the objects width. Useful if you are programming your own uiz objects.

This a generic function used to calculate the position or size within an object. A ui object will call this function to know how it should position or size drawable parts inside of the object. For example: a slider might be 200px wide, but the slider also has a knob. The slider uses this function internally to check how big the sliderknob should be.

This function changes a position/distance from a value and valuetype pair to a usable single pixel value.

arguments

uiz_getposx/y_self(value,valuetype[px dp fc]):

• value: What position/length should be calculated in combination with the valuetype
• valuetype: What type of value the first value is. This accepts:
  • px
  • pxmin
  • dp
  • dpmin
  • fc
  • fcx
  • fcy
  • fcm
  • fcmin
  • fcmax

Value types

The explanations have been adapted from here to be relavent to this function.

px

This is the simpelest type and simply returns the given value, because it's already in pixel form. If you give a value of 3, the size/position you are trying to get is 3 pixels wide.

pxmin

The given pixel value subtracted from the object's width (for the x function) or height (for the y function). This is useful if you want to put something inside an object with a pixel margin.

dp

Dp stands for "Density pixels". One dp equals 1 inch or 2.54 cm in real life.

dpmin

The given dp value subtracted from the object's width (for the x function) or height (for the y function). This is useful if you want to put something inside an object with a dp margin.

fc

This function takes the object's width (for the x function) or height (for the y function) and multiplies it by the value. You can make your attribute 50% of it's object's size by setting a value of .5 and a valuetype of fc. (If we would apply this example to our slider, the sliderknob would be half the width of the object)

fcx

This function does the same as fc, but always takes the object's width, no matter if the x or y variant of this function is called.

fcy

This function does the same as fc, but always takes the object's height no matter if the x or y variant of this function is called.

fcm

This function calculates both the fcx value and fcy value and takes the average between those values.

fcmin

This function looks at the object's width and height. If the height is smaller than the width fcy is used, else fcx is used.

fcmax

This function looks at the object's width and height. If the height is larger than the width fcy is used, else fcx is used.
