How it works

Forks

Each fork represents a state of the element. If an element supports 2 or more forks, it reserves the first few (dependent on he amount of forks) children for the different states. For example you have a uibutton which has 3 forks, the first 3 children are used to solely represent its states. If we were to give it 4 children, and then hover over the button, child #2 and child #3 will be drawn, this is demonstrated below. A rule of thumb is to make the absolute minimum amount of children for an element the amount of forks it has.


 uibutton [echo "Hello World"] [
   uiimage "data/hud/2.1/icons/action.jpg" .05 .05 //shown when idle
   uiimage "data/hud/2.2/icons/action.jpg" .05 .05 //shown on hover
   uiimage "data/hud/2.3/icons/action.png" .05 .05 //shown on click
   uiimage "data/hud/blackfog/icons/action.png" .02 .02 //always shown
 ]

Siblings

The more obvious definition is for elements to be declared next to each other to be siblings. Not quite so, the relationship can be one way as a parent is also considered a sibling for lookup purposes, although a child is not. This example is a standard scrolling container, uiscroll requires a uiscrollbar sibling to determine offsets and although not necessary, uiscrollbar works best with a uiscrollbutton child.


 uiscroll .94 1 [
   ...
 ]
 uiscrollbar .06 1 [
   ....
   uiscrollbutton [
     ...
   ]
 ]

Children

The obvious definition once again, elements defined in the children argument of another element. Almost all newui elements allow additional children to be spawned. Similar to siblings, any children of the children (as well as their respective children) also also counted as children of the current element. Children are a very important concept with this ui system as they are required for many of the elements to operate correctly. Remember elements need as least as many children as there are forks. This is demonstrated in the examples above.

States

Each fork is reached by the element exhibiting a certain state. You can find more detailed information on the available states for each element in the element's respective section. This area just discusses some of the more common states and how they are reached.

For items that utilise mouse based interactivity

Idle - when your cursor is not hovering over the element, nor is it selected
Hovering - when your cursor hovers over the element without clicking it
Selected - when you click the element, you do not necessarily have to be hovering over it

For items with a conditional

True - provided conditional evaluates to true
False - absence of conditional or provided conditional evaluates to false

Remember to place the conditionals inside [] blocks, ie


 uicond [= $cond 1] [
   ...
 ]

Creating

When making menus or other miscellaneous UIs through this, you should place the showui command within an alias named showMYMENU, where MYMENU is substituted for the name of the menu. For example...


 showMYMENU = [
   showui MYMENU [
     ...
   ]
 ]

Commands

hideui

Arguments: Name

Hides the UI which matches the name

replaceui

Arguments: Name Tag Children

within the named UI, it finds the tag which matches the provided name replaces its children. Note that if these arguments are supplied as a child to one of the elements, it'll be ignored.

showui

Arguments: Name Children On-Hide

Creates a UI named Name which contains the provided children. The On-Hide script (if provided) is executed when the UI is closed

uialign

Arguments: X Y

both arguments can be one of -1, 0 or 1. -1 refers to the top left and 1 to the bottom right. For example, uialign 1 0 will align things to the right. Note this only applies to its parent object. and only has a visible effect if there's space to move.

uialtimage

Arguments: Image

Replaces the image of the prior element with this one, should it fail to load. It only works if its parent utilises an image and is the first child!

uiclamp

Arguments: Left Right Bottom Top

This will cause the parent's edges to snap to the boundaries you provided true values for. It should be noted that as a child these boundaries are defined by it's parent.

For example, uicolor here will utilise all the available space from uifill


 uifill .4 .4 [
   uicolor 1 1 1 1 0 0 [uiclamp 1 1 1 1]
 ]

Elements

NOTE: these names of the classes do not necessarily correspond to the names of the commands to call them. if you want information of a specific command, please use ctrl-F to find it

BorderedImage

Arguments: Image TexBorder ScreenSize Children
Forks: 0
Siblings: None
Children: None
Provided By: uiborderedimage
See Also: CroppedImage Image StretchedImage SlotViewer

This turns the provided image into a border, or a frame. ScreenSize determines the border size and TexBorder determines a texture offset from which to create the borders. If the the literal provided to TexBorder contains a lowercase p somewhere after the number, it will be interpretted as pixels. Also note that without any children, only the corners will be rendered.
A handy tip for creating the children is to use uispace to offset them away from the border: ie uispace ScreenSize ScreenSize [children here]

Button

Arguments: Action Children
Forks: 3
- fork1: Idle
- fork2: Hovering
- fork3: Selected
Siblings: None
Children: None
Provided By: uibutton

Clipper

Arguments: X-Size y-Size Children
Forks: 0
Siblings: None
Children: None
Provided By: uiclip
See Also: Scroller

This is like Scroller, except you cannot scroll

CroppedImage

Arguments: Image X-Size Y-Size X-Start Y-Start X-End Y-End
Forks: 0
Siblings: None
Children: None
Provided By: uicroppedimage
See Also: BorderedImage Image StretchedImage SlotViewer

For the *-Start and *-End arguments, if there's a p present somewhere after the number, it'll be interpreted as an amount of pixels instead of a percentage. You can enter whatever you want before or after the p, it will be interpreted as pixels as long a lower case p is present.

Conditional

Arguments: Condition Children
Forks: 2
- fork1: True
- fork2: False
Siblings: None
Children: None
Provided By: uicond
See Also: ConditionalButton Toggle

If you only want it to display stuff while false, use "uifill 0 0" as the true child. If you do not wish to have anything display in the false case, you can use uifill 0 0 or not provide a child.

ConditionalButton

Arguments: Condition On-Select Children
Forks: 4
- fork1: False idle
- fork2: True idle
- fork3: True hover
- fork4: True select
Siblings: None
Children: None
Provided By: uicondbutton
See Also: Conditional Toggle

It should be noted this button is only selectable if the condition is true. If the condition is false clicking the button will not heed in any results.

Filler

Arguments: X-Size Y-Size Children
Forks: 0
Siblings: None
Children: None
Provided By: uifill

Use this if you want to create a UI without a backdrop

Image

Arguments: Image W-Size H-Size Children
Forks: 0
Siblings: None
Children: None
Provided By: uiimage
See Also: StretchedImage CroppedImage BorderImage SlotViewer

List

Arguments: Space Children
Forks: 0
Siblings: None
Children: None
Provided By: uihlist uivlist

Space is the amount of padding between the contained elements. We generally recommend using this to create Children for a Scroller.

Offsetter

Arguments: W-Offset H-Offset Children
Forks: 0
Siblings: None
Children: None
Provided By: uioffset

it essentially moves the elements this much

Rectangle

Arguments1: R G B A W-Size H-Size Children (uicolor)
Arguments2: R G B W-Size H-Size Children (uimodcolor)
Forks: 0
Siblings: None
Children: None
Provided By: uicolor uimodcolor

The difference between the two is that the first draws a solid rectangle, and the second draws one which modulates the colour of the UI.

ScrollBar

Arguments: Image W-Size H-Size Children
Forks: 5
- fork1: Idle
- fork2: Hovering over up/left arrow
- fork3: Selected up/left arrow
- fork4: Hovering over down/right arrow
- fork5: Selected down/right arrow
Siblings: Scroller
Children: ScrollButton
Provided By: uihscrollbar uivscrollbar

ScrollButton

Arguments: Children
Forks: 3
- fork1: Idle
- fork2: Hovering
- fork3: Selected
Siblings: None
Children: None
Provided by: uiscrollbutton

Scroller

Arguments: W-Size H-Size Children
Forks: 0
Siblings: None
Children: None
Provided By: uiscroll

For most cases, List and Table elements should be used to create the content inside. It should be noted without a ScrollBar it is practically the same as a Clipper.

SlotViewer

Arguments: Slot W-Size H-Size Children
Forks: 0
Siblings: None
Children: None
Provided By: uiviewslot

Spacer

Arguments: X-padding Y-Padding Children
Forks: 0
Siblings: None
Children: None
Provided By: uispace

uispace places the padding around its children, so the space consumed is essentially twice as much as you tell it to. This is useful for getting the elements away from the edges.

StretchedImage

Arguments: Image W-Size H-Size Children
Forks: 0
Siblings: None
Children: None
Provided By: uistretchedimage
See Also: Image BorderedImage CroppedImage

Table

Arguments: Columns Padding Children
Forks: 0
Siblings: None
Children: None
Provided By: uitable

Should you exhaust all the columns, the table will start afresh on a new row. If you intend to have a bunch of items span across and down the screen in a constant grid, we recommend using this to generate items for a Scroller element.

Tag

arguments: Name Children
forks: 0
siblings: None
children: None
provided by: uitag

replaceui can be used to replace the contents of a tag

Text

Arguments1: Text Size Children (uitext)
Arguments2: Text Size R G B Children (uicolortext)
Forks: 0
Siblings: None
Children: None
Provided By: uitext uicolortext

TextEditor

Arguments: Name Length Height Scale InitialValue Keep Filter Children
Forks: 0
Siblings: None
Children: None
Provided By: uitexteditor

Name refers to a unique name for the editor. Any editor with a matching name edits the same items.
Length and Width state how many characters wide and how many characters high the field is.
If Keep is true, focus is not lost should the mouse move away from the field.
Filter is a collection of characters. Any characters within this list can't be used. for example "aeiou" will prevent the use of vowels.

Toggle

Arguments: Condition On-Select Split Children
Forks: 4
- fork1: false idle
- fork2: false hovering
- fork3: true idle
- fork4: true hovering
Siblings: None
Children: None
Provided By: uitoggle
See Also: Conditional ConditionalButton

We would recommend using this to create the likes of checkboxes and tabs. The action is executed regardless of whether or not the condition is false, unlike uicondbutton.
