README

Windows GUI Library

This is a pure Go library to create native Windows GUIs. See the online documentation for details.

Minimal Example

This is all the code you need to create a window (which does not do much).

package main

import "github.com/gonutz/wui/v2"

func main() {
	wui.NewWindow().Show()
}

The Designer

I am currently working on a graphical designer. It is located under github.com/gonutz/wui/v2/cmd/designer.

At the moment it lets you place widgets graphically and generate a Go main file from it (using the Save menu). You can also run a preview with Ctrl+R.

There is no way to read the generated code back in at the moment. Right now it is a tool to place things and generate code from it.

	// AnchorMax makes a control stick to the right/bottom side of its parent.
	// The control's size is not changed.
	AnchorMax

	// AnchorCenter keeps a control fixed at the horizontal/vertical center of
	// its parent, e.g. if it is placed 10 pixels left of the center, it will
	// stay 10 pixels left of its parent's center. Its size is not changed.
	AnchorCenter

	// AnchorMinAndMax makes a control's borders stick to its parent's borders.
	// The size changes propertionally to its parent's size, keeping the
	// original distances to its parents borders.
	AnchorMinAndMax

	// AnchorMinAndCenter makes the left/top side of a control stick to its
	// parent's left/top side while the right/bottom side sticks to the parent's
	// center.
	AnchorMinAndCenter

func NewCursorFromImage(img image.Image, x, y int) (*Cursor, error)

NewCursorFromImage creates a cursor with 4 possible colors: black, white, transparent and inverse screen color. Inverse screen color depends on what is under the cursor at any time. The cursor will be white minus the screen color to give maximum contrast for such pixels.

Fully opaque black and white pixels in the image are interpreted as black and white.

Fully transparent pixels in the image are interpreted as screen color.

All other pixels are interpreted as inverse screen color. This means even "almost" black/white/transparent, say with intensity 0xFFFE instead of 0xFFFF, will be interpreted as inverse screen color.
