Package gui implements a abstraction layer for Go visual elements in
a cross platform way.
A quick overview of the features, some general design guidelines
and principles for how this package should generally work:
* GUI elements are stored in a tree of nodes
* When in doubt, it's ok to guess. We will return something close.
* It tries to make your code simple
Quick Start
This section demonstrates how to quickly get started with spew. See the
sections below for further details on formatting and configuration options.
// This creates a simple hello world window
package main
import (
"git.wit.org/wit/gui"
)
func main() {
gui.Main(initGUI)
}
// This initializes the first window
func initGUI() {
gui.Config.Title = "Hello World golang wit/gui Window"
gui.Config.Width = 640
gui.Config.Height = 480
node1 := gui.NewWindow()
addDemoTab(node1, "A Simple Tab Demo")
addDemoTab(node1, "A Second Tab")
}
func addDemoTab(n *gui.Node, title string) {
newNode := n.AddTab(title, nil)
groupNode1 := newNode.AddGroup("group 1")
groupNode1.AddComboBox("demoCombo2", "more 1", "more 2", "more 3")
}
Configuration Options
Configuration of the GUI is handled by fields in the ConfigType type. For
convenience, all of the top-level functions use a global state available
via the gui.Config global.
The following configuration options are available:
* Width
When creating a new window, this is the width
* Height
When creating a new window, this is the height
* Debug
When 'true' log more output
Toolkit Usage
Right now, this abstraction is built on top of the go package 'andlabs/ui'
which does the cross platform support.
The next step is to intent is to allow this to work directly against GTK and QT.
It should be able to add Fyne, WASM, native macos & windows, android, etc.
Errors
Since it is possible for custom Stringer/error interfaces to panic, spew
detects them and handles them internally by printing the panic information
inline with the output. Since spew is intended to provide deep pretty printing
capabilities on structures, it intentionally does not return any errors.
Debugging
To dump variables with full newlines, indentation, type, and pointer
information this uses spew.Dump()
