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.

	// control's size is not changed.

	// 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

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.

func (*StringList) SetSelectedIndex added in v2.8.0 

func (l *StringList) SetSelectedIndex(i int)

SetSelectedIndex sets the current index. Set -1 to remove any selection and make the list box empty. If you pass a value < -1 it will be set to -1 instead. The index is not clamped to the number of items, you may set the index 10 where only 5 items are set. This lets you set the index and items at design time without one invalidating the other. At runtime though, SelectedIndex() will return -1 if you set an invalid index.

func (*TextEdit) CharacterLimit added in v2.6.1 

func (e *TextEdit) CharacterLimit() int

func (*TextEdit) CursorPosition added in v2.6.1 

func (c *TextEdit) CursorPosition() (start, end int)

CursorPosition returns the current cursor position, respectively the current selection.

If no selection is active, the returned start and end values are the same. They then indicate the index of the UTF-8 character in this EditLine's Text() before which the caret is currently set.

If a selection is active, start is the index of the first selected UTF-8 character in Text() and end is the position one character after the end of the selection. The selected text is thus 

c.Text()[start:end]
