Len is the length of the editor contents, in runes.

MoveLineEnd moves the caret to the end of the current line, ensuring that the resulting cursor position is on a grapheme cluster boundary.

Update the widget state and report whether Value was changed.

Constrain a size so each dimension is in the range [min;max].

Contain reports whether m contains all modifiers in m2.

Focused reports the focused key, or false if no key is focused.

Invalidate requests a FrameEvent.

Layout a List of len items, where each item is implicitly defined by the callback w. Layout can handle very large lists because it only calls w to fil

MoveFocus attempts to move the focus in the direction of dir.

NewAffine2D creates a new Affine2D transform from the matrix elements in row major order. The rows are: [sx, hx, ox], [hy, sy, oy], [0, 0, 1].

Rigid returns a Flex child with a maximal constraint of the remaining space.

MaxLines moves the cursor the specified number of lines vertically, ensuring that the resulting position is aligned to a grapheme cluster.

Selection returns the start and end of the selection, as rune offsets. start can be > end.

Elems returns the matrix elements of the transform in row-major order. The rows are: [sx, hx, ox], [hy, sy, oy], [0, 0, 1].

Fill paints an infinitely large plane with the provided color. It is intended to be used with a clip.Op already in place to limit the painted area. Us

Invert the transformation. Note that if the matrix is close to singular numerical errors may become large or infinity.

RunesIndex converts the given index in utf16 characters to an index in runes.

SetCaret moves the caret to start, and sets the selection end to end. start and end are in runes, and represent offsets into the editor text.

Div returns the vector p/s.

Empty reports whether r represents the empty area.

Progression returns the way that the text flows relative to the origin.

Stop any remaining fling movement.

WakeupTime returns the most recent time for doing another frame, as determined from the last call to Frame.

initialize must be called at the beginning of any exported method that manipulates text state. It ensures that the underlying text is safe to access.

FPt converts an point to a f32.Point.

Len is the length of the editor contents, in runes.

MoveWord moves the caret to the next word in the specified direction. Positive is forward, negative is backward. Absolute values greater than one will

MulAlpha applies the alpha to the color.

Valid will return true when the ViewEvent does contains valid handles. If a window receives an invalid ViewEvent, it should deinitialize any state ref

Dp converts v to pixels.

Layout lays out the editor using the provided textMaterial as the paint material for the text glyphs+caret and the selectMaterial as the paint materia

Layout the list and its scrollbar.

Shear the transformation by the given angle (in radians) around the given origin.

addPointerHandler adds a pointer.InputOp for the tag in a rectangular area.

exception returns an error corresponding to the pending exception, or nil if no exception is pending. The pending exception is cleared.

fromFixed converts a Wayland wl_fixed_t 23.8 number to float32.

nsstringToString converts a NSString to a Go string.

Clicked calls Update and reports whether a click was registered.

Hovered reports whether pointer is over the element.

Move moves the pen by the amount specified by delta.

MoveCaret moves the caret (aka selection start) and the selection end relative to their current positions. Positive distances moves forward, negative

NewWindow creates a new headless window.

Selection returns the start and end of the selection, as rune offsets. start can be > end.

Stacked returns a Stack child that is laid out with no minimum constraints and the maximum constraints passed to Stack.Layout.

runeOffset returns the byte offset into e.rr of the r'th rune. r must be a valid rune index, usually returned by closestPosition.
