me.hackware.api.gui.UiContext

public final class UiContext
extends Object

Per-frame render context and primitive-drawing toolkit shared by the ClickGUI component kit (see this package). Works in raw GUI coordinates — the same space mouse events arrive in — so hit-testing is trivial and the rounded-rect helper (GuiUtils.fillRoundedRect(net.minecraft.client.gui.GuiGraphics, double, int, int, int, int, int, int)) quantises to real pixels via the window GUI scale.

Bound only to a base Screen + Font, so both the Macros tab and the radial-menu screen can use it. Colours come from GuiTheme (accent + text tiers) plus a small set of dark, shadcn-flavoured surface tokens.

Constructor Details

UiContext

public UiContext(net.minecraft.client.gui.screens.Screen screen,
 net.minecraft.client.gui.GuiGraphics g,
 net.minecraft.client.gui.Font font,
 int mouseX,
 int mouseY)

Method Details

timing

public UiContext timing(float frameDeltaMs,
 boolean animationsEnabled)

Supplies animation timing (from the host screen) for smooth scrolling.

scaled

public UiContext scaled(float uiScale)

Declares that rendering happens inside a pose scaled by uiScale (e.g. the ClickGui panel scale), with mouse coordinates already converted to that logical space. Keeps physical-pixel radii/borders resolving to real pixels through the extra transform.

accent

public int accent()

textPrimary

public int textPrimary()

textSecondary

public int textSecondary()

textMuted

public int textMuted()

accentBg

public int accentBg(float opacity)

The accent colour tinted onto a dark background — for accent chips / fills behind text.

hover

public boolean hover(int x,
 int y,
 int w,
 int h)

pointIn

public static boolean pointIn(double px,
 double py,
 int x,
 int y,
 int w,
 int h)

rect

public void rect(int x,
 int y,
 int w,
 int h,
 int color)

roundRect

public void roundRect(int x,
 int y,
 int w,
 int h,
 int radiusPx,
 int color)

Rounded fill. radiusPx is in physical pixels (see R_SM etc.).

roundRectBorder

public void roundRectBorder(int x,
 int y,
 int w,
 int h,
 int radiusPx,
 int fill,
 int border)

Rounded fill with a 1-physical-pixel hairline border.

roundRectOutline

public void roundRectOutline(int x,
 int y,
 int w,
 int h,
 int radiusPx,
 int color)

A 1-physical-pixel rounded outline only — no fill (outlined buttons etc.).

roundRectOutline

public void roundRectOutline(int x,
 int y,
 int w,
 int h,
 int radiusPx,
 int thicknessPx,
 int color)

Rounded outline with an explicit physical thickness (focus rings etc.).

focusRing

public void focusRing(int x,
 int y,
 int w,
 int h,
 int radiusPx,
 int color)

The focused-input accent ring: an EXTERIOR ring at double the normal border width, sitting in the band just OUTSIDE the field's edge (its inner edge flush to the box), so focus reads as a ring around the field growing outward — not a thick inset border. x,y,w,h/radiusPx are the field's own bounds.

darken

public static int darken(int argb,
 float factor)

Darkens an ARGB colour by the given factor (0 = unchanged, 1 = black).

elevate

public void elevate(int x,
 int y,
 int w,
 int h,
 int radiusPx)

Cheap elevation: a faint rounded shadow offset one px below the surface.

hairlineH

public void hairlineH(int x,
 int y,
 int w,
 int color)

A horizontal hairline exactly 1 physical pixel tall (separator rules).

hairlineV

public void hairlineV(int x,
 int y,
 int h,
 int color)

A vertical hairline exactly 1 physical pixel wide (separator rules).

toPx

public int toPx(int guiRadius)

GUI-space radius → physical-pixel radius (for circles sized in GUI px, e.g. ripples).

borderPx

public int borderPx()

Focus-ring / input-border thickness in native px: a 2 logical-px stroke scaled by the ClickGui panel zoom only. res folds in BOTH the MC gui density and the panel zoom, so toPx(2) (=2·guiScale·uiScale) reads as "2px × scale" — far too thick. Dividing the density back out leaves 2·uiScale: a clean exterior 2px border that tracks the panel without ballooning at high gui scales.

scissorOn

public void scissorOn(int x,
 int y,
 int w,
 int h)

Scissors logical-space coordinates. Transforms the rect by the current pose manually and neutralises the pose for the actual scissor call (mirrors ClickGUIScreen.enablePanelScissor) so scaled poses don't shave a pixel off the edges via float round-tripping.

scissorOn

public void scissorOn(int x,
 int y,
 int w,
 int h,
 boolean vInside)

As scissorOn(int, int, int, int), but when vInside is true the top/bottom edges are pulled inward by V_CLIP_INSET of a gui pixel before rounding, rather than expanding outward. The default outward rounding (floor top, ceil bottom) lets content bleed past the viewport at fractional panel scales; a whole-pixel inward pull (ceil/floor) over-corrects by a full gui pixel — which is guiScale physical pixels once MC scales the clip rect to the framebuffer. The fractional pull is the tuned minimum that still keeps rows from spilling over an adjacent divider (top) or border (bottom). Horizontal edges stay outward.

scissorOff

public void scissorOff()

scissorRaw

public void scissorRaw(int gx1,
 int gy1,
 int gx2,
 int gy2)

Scissors a rect given directly in vanilla GUI space (post-pose), the finest granularity the scissor supports — used for per-pixel gradient slicing.

text

public void text(String s,
 int x,
 int y,
 int color)

textShadow

public void textShadow(String s,
 int x,
 int y,
 int color)

textCentered

public void textCentered(String s,
 int x,
 int y,
 int w,
 int color)

Draw text centred within [x, x+w].

textWidth

public int textWidth(String s)

lineHeight

public int lineHeight()

tinyText

public void tinyText(String s,
 int x,
 int y,
 int color)

Half-scale text for micro adornments (badges, popup footers, type tags).

tinyTextWidth

public int tinyTextWidth(String s)

Width of tinyText(java.lang.String, int, int, int) for s, in logical px.

textItalic

public void textItalic(String s,
 int x,
 int y,
 int color)

Italic text (for type tags / hints), full scale.

textItalicWidth

public int textItalicWidth(String s)

Width of textItalic(java.lang.String, int, int, int) for s (includes the italic skew).

iconCentered

public void iconCentered(Icons.Icon icon,
 float cx,
 float cy,
 int size,
 int color)

Draw a tintable icon sprite (Icons) at size, centred on (cx,cy), tinted color.

ellipsize
