Functions

ControlledBy

User-defined attribute you can add to struct members contrlled by addDataControllerWidget or dialog to tell which widget you want created for them.

addDataControllerWidget

DataControllerWidget!T addDataControllerWidget(Widget parent, T* t, Widget redrawOnChange)

Intended for UFCS action like window.addDataControllerWidget(new MyObject());

addDataControllerWidget

DataControllerWidget!T addDataControllerWidget(Widget parent, T t, Widget redrawOnChange)

Intended for UFCS action like window.addDataControllerWidget(new MyObject());

addWhenTriggered

void addWhenTriggered(Widget w, void delegate() dg)

Convenience function to add a triggered event listener.

consumesCommand

EventListener consumesCommand(WidgetType w, void delegate(Args) handler)

Declares that the given widget consumes a command identified by the CommandString AND containing Args. Your handler is called with the arguments, then the event's propagation is stopped, so it will not be seen by the consumer's parents.

createWin32Window

void createWin32Window(Widget p, const(wchar)[] className, string windowText, DWORD style, DWORD extStyle)

Calls MS Windows' CreateWindowExW function to create a native backing for the given widget. It will create needed mappings, window procedure hooks, and other private member variables needed to tie it into the rest of minigui's expectations.

dialog

void dialog(void delegate(T) onOK, void delegate() onCancel, string title)

void dialog(T initialData, void delegate(T) onOK, void delegate() onCancel, string title)

Creates a dialog based on a data structure.

emitCommand

void emitCommand(WidgetType w, Args args)

Emits a command to the sender widget's parents with the given CommandString and args. You have no way of knowing if it was ever actually consumed due to the loose coupling. Instead, the consumer may broadcast a state update back toward you.

getOpenFileName

void getOpenFileName(void delegate(string) onOK, string prefilledName, string[] filters, void delegate() onCancel, string initialDirectory)

getSaveFileName

void getSaveFileName(void delegate(string) onOK, string prefilledName, string[] filters, void delegate() onCancel, string initialDirectory)

Gets a file name for an open or save operation, calling your onOK function when the user has selected one. This function may or may not block depending on the operating system, you MUST assume it will complete asynchronously.

messageBox

MessageBoxButton messageBox(string title, string message, MessageBoxStyle style, MessageBoxIcon icon)

int messageBox(string message, MessageBoxStyle style, MessageBoxIcon icon)

Displays a modal message box, blocking until the user dismisses it.

import arsd.minigui_xml;
import arsd.script;

var globals = var.emptyObject;
globals.makeWidgetFromString = &makeWidgetFromString;

// this now works
interpret(`var window = makeWidgetFromString("<MainWindow />");`, globals);

import arsd.minigui;

void main() {
	auto window = new MainWindow();

	// note the parent widget is almost always passed as the last argument to a constructor
	auto hello = new TextLabel("Hello, world!", TextAlignment.Center, window);
	auto button = new Button("Close", window);
	button.addWhenTriggered({
		window.close();
	});

	window.loop();
}

import arsd.minigui;

// This helper class is just to help make the layout boxes visible.
// think of it like a <div style="background-color: whatever;"></div> in HTML.
class ColorWidget : Widget {
	this(Color color, Widget parent) {
		this.color = color;
		super(parent);
	}
	Color color;
	class Style : Widget.Style {
		override WidgetBackground background() { return WidgetBackground(color); }
	}
	mixin OverrideStyle!Style;
}

void main() {
	auto window = new Window;

	// the key is to give it a max height. This is one way to do it:
	auto header = new class HorizontalLayout {
		this() { super(window); }
		override int maxHeight() { return 50; }
	};
	// this next line is a shortcut way of doing it too, but it only works
	// for HorizontalLayout and VerticalLayout, and is less explicit, so it
	// is good to know how to make a new class like above anyway.
	// auto header = new HorizontalLayout(50, window);

	auto bar = new HorizontalLayout(window);

	// or since this is so common, VerticalLayout and HorizontalLayout both
	// can just take an argument in their constructor for max width/height respectively

	// (could have tone this above too, but I wanted to demo both techniques)
	auto left = new VerticalLayout(100, bar);

	// and this is the main section's container. A plain Widget instance is good enough here.
	auto container = new Widget(bar);

	// and these just add color to the containers we made above for the screenshot.
	// in a real application, you can just add your actual controls instead of these.
	auto headerColorBox = new ColorWidget(Color.teal, header);
	auto leftColorBox = new ColorWidget(Color.green, left);
	auto rightColorBox = new ColorWidget(Color.purple, container);

	window.loop();
