DFL (D Forms Library) is a Win32 GUI library for the D language.

import dfl;

void main()
{
	Application.enableVisualStyles();
	
	Form form = new Form;
	form.text = "Welcome to DFL";
	form.size = Size(300, 300);

	Button button = new Button;
	button.text = "OK";
	button.location = Point(20, 20);
	button.size = Size(100, 50);
	button.click ~= (Control c, EventArgs e) => msgBox("OK button is clicked.");
	button.parent = form;

	Application.run(form);
}

• Supports dpi-aware (per monitor v2).

  • Add Application.setHighDpiMode method.
    • DPI_UNAWARE
    • SYSTEM_AWARE
    • PER_MONITOR
    • PER_MONITOR_V2
    • DPI_UNAWARE_GDI_SCALED
  • Add Control.onDpiChanged method for recursive dpi-change.

• Add LocationAlignment property to Control class for easily layout customize GUI elements (with example code) .

  • While WinForms' Anchor maintains a constant distance to the edge of the parent control, LocationAlignment sets the distance to the edge of the parent control to zero.
  • LocationAlignment is affected by the dockMargin property.
  • LocationAlignment and DockStyle cannot be used at the same time.

• Enabled padding and margin configuration for all Control types.
• StackPanel class and example code are now comming.

• Reworked build-scripts (makelib.bat, makecoff.bat and go.bat) to better work with DUB and MSVC 2022.
  • dfl.lib and dfl_debug.lib are created in \dfl\bin, just like DUB.
• Module "dfl.toggleswitch" and example code are now comming.

• Module "dfl.toastnotifier" is now comming (with example).
  • ToastNotifier
  • ToastNotifierLegacy

• Registered DFL to DUB.
• Module "dfl.chart" is now comming (with example).
  • TableRenderer
  • LineGraphRenderer
  • TimeChartRenderer
• Module "dfl.printing" is now comming (with example).
  • PrintDialog
  • PrintSetupDialog
  • PrintPreviewDialog
• Remove some bundled libraries such as user32_dfl.lib etc... (From now on, use dmd-bundled libraries such as the MinGW platform library and so on.)

First, you make new DUB project:

> cd examples\new_project
> dub init

Add DFL to local DUB registry:

> dub add dfl
> dub list
Packages present in the system and known to dub:
  dfl 0.11.3: c:\your\path\dfl\0.11.3\dfl\
  silly 1.2.0-dev.2: c:\your\path\silly\1.2.0-dev.2\silly\

Build and run your GUI applications with DUB as below:

> dub build -a=x86_64
> dub run

IMPORTANT: DUB is building dfl_dub.lib that is not containing WINSDK libraries.

Free downloads MSVC build tools from https://visualstudio.microsoft.com/vs/community/.

Fix the paths below:

set dmd_path=c:\d\dmd2\windows

Open x64 Native Tools Command Prompt for VS 2022 from start menu.

Run makelib.bat (MSVC required):

> cd dfl

> dir *.bat /B
go.bat
makecoff.bat
makelib.bat
_cmd.bat

> makelib.bat           # 32-bit mscoff

or (MSVC required)

> makelib.bat 32mscoff  # ditto

or (MSVC required)

> makelib.bat 64        # 64-bit mscoff

Also copy dfl.lib and dfl_debug.lib in \dfl\bin to \your\lib\dir.

IMPORTANT: These library files are containing WINSDK libraries such as user32.lib, gdi32.lib and so on.

In order to make and move *.lib to paths below:

• go.bat (MSVC required) : Make and move *.lib to %dmd_path%\lib32mscoff
• go.bat 32mscoff (MSVC required) : ditto
• go64.bat (MSVC required) : Make and move *.lib to %dmd_path%\lib64

1. If you use dfl.internal.winrt, install Visual Studio 2022 and Windows 10 SDK (10.0.19041.0) or newer.
2. You must link WindowsApp.lib contained the SDK to your application.
