mac-playground's Introduction

mac-playground

This is a mix of code that was developed during our effort to port eM Client to macOS. It is a hodgepodge of various projects and experiments. The notable ones are listed below. The code is released as-is.

To test the experiments:

Make sure .NET 6 SDK for macOS is installed
Run dotnet workload restore from the Terminal
Open solution folder in Visual Studio Code or Visual Studio
Run the test application

System.Drawing

The System.Drawing directory contains a fork of the https://github.com/mono/sysdrawing-coregraphics project. We have enhanced the API surface to be compatible enough with System.Drawing to run System.Windows.Forms on top of it. In addition we have implemented some missing APIs and fixed compatibility issues with pixel rounding.

System.Windows.Forms

The System.Windows.Forms directory contains a fork of the Mono System.Windows.Forms implementation. It contains a Cocoa backend to allow applications run on 64-bit macOS systems. Layout code was heavily overhauled and debugged on both a test application and a full UI of eM Client. Further experiments were made with replacing some controls with their native counterparts (akin to https://github.com/Clancey/MonoMac.Windows.Form), which can be done on per-control basis.

mac-playground's Issues

Debugging doesn't work with VS Code (OmniSharp 1.25.2)

If the debugger in VS Code hangs, you can use the following workaround:

curl -sSL https://aka.ms/getvsdbgsh | bash /dev/stdin -v latest -l ~/vsdbg
cp ~/vsdbg/libdbgshim.dylib ~/.vscode/extensions/ms-dotnettools.csharp-1.25.2-darwin-arm64/.debugger/arm64/

API implementation or DrawReversibleFrame and FillReversibleRectangle

I need to use the API of DrawReversibleFrame and FillReversibleRectangle, but they are not implemented neither in XplatUICocoa.cs nor in XplatUICarbon.cs.

		internal override void DrawReversibleLine(Point start, Point end, Color backColor) {
//			throw new NotImplementedException();
		}

		internal override void FillReversibleRectangle (Rectangle rectangle, Color backColor) {
//			throw new NotImplementedException();
		}

		internal override void DrawReversibleFrame (Rectangle rectangle, Color backColor, FrameStyle style) {
//			throw new NotImplementedException();
		}

Can you give me some thought on how to implement them in Cocoa?

Thanks

SelectedIndex not working as expected for DropDown combo box

I noticed that ComboBox.SelectedIndex does not have the expected value -1 when text was entered which is not part of the list (https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.combobox.selectedindex?view=netframework-4.7.2).

This can happen with DropDownStyle = ComboBoxStyle.DropDown. A user can type any text and hit return. This does not lead to a SelectedIndexChanged event. But on Windows SelectedIndex will subsequently return -1.

With the current implementation the behavior is different. ComboTextFieldChanged does not call OnImpSelectedItemChanged since indexofCompleted == -1. In turn the combo's SelectedIndex will have its old value and not -1.

I believe the right fix is something like

if (indexofCompleted != -1)
     owner.OnImpSelectedItemChanged(sender, e);
else
     owner.SelectedIndexChanged();

in ComboBoxImp.ComboTextFieldChanged where SelectedIndexChanged is a new method that updates selected_index but does not raise any events. However, my understanding of the combobox implementation isn't deep enough to submit a pull request without asking.

Reference to MailClient.BuildTasks.targets: cannot find that file

[Disclaimer: I am new to building WinForms applications using Visual Studio and completely new to mac-playground]

Setup and background:
running 10.15.3 (Catalina) which being 64bit cannot run WinForms apps out of the box
running VS for Mac 8.4.8
Xamarin.Mac Version: 6.10.0.21 (Visual Studio Community)
cloned mac-playground into fresh directory
build fails as the file above does not exist

Purpose:
I want to try using mac-playground as a way forward to recompiling my old WinForms application; but
tried a search and StackOverflow sites but finding nothing

The type initializer threw an exception

I heard that this application allows users to use x64bit winforms on MacOS. I tried to follow the instructions in the readme and I got this while opening up the .sln file:

Error while trying to load the project 'filepath/mac-playground-master/FormsTestApp/FormsTest.app.csproj': The type initializer for 'MonoDevelop.MonoMac.XamMac2ProjectFlavor' threw an exception.

Text boxes don't have context menus and don't allow copy/paste through keyboard shortcuts

Unlike most native controls text boxes do not show a context menu on right click. There is one exception: When right-clicking on a TextBoxBase_NSTextView while it does not have focus the macOS context menu is shown. It does not work when right-clicking after the control was activated.

Also Apple+C/V/X shortcuts don't work.

I'd be happy to trying adding the functionality. However, I'm wondering if overriding the mouse button and key down events and adding the required calls here is would be the right approach.

@filipnavara Can you share any hints?

OpenFileDialog and SaveFileDialog classes don't have OpenFile method

Color dialog not fully working

I noticed that the color dialog is not working properly as shown in this screenshot.

The column with shades on the right should update to the selected color, if I remember correctly
Entering numeric values has no effect (e.g. red=green=0, blue=255 should show blue)

I don't really need the control and maybe instead of fixing the Mono dialog an implementation based on NSColorWell is a better approach. Just wanted to make sure to record the issue for now.

ApplicationShouldTerminate without main form

First of all, great SWF Cocoa port!

I tried to run it for an application that does not have a main window which is always present. One thing I noticed is that the ApplicationShouldTerminate event is not received when no form is open.

I tracked this down to the call NSApp.NextEvent(dequeue:=false) which apparently does not process ApplicationShouldTerminate. NSApp.NextEvent(dequeue:=true) does.

Therefore I'm suggesting the attached patch. Would you mind reviewing if the suggested change makes sense?

macOS 13 CoreGraphics Deprecation

Not sure it's the right place to bring this up. There's this upcoming deprecation in macOS 13 in CoreGraphics which I couldn't quickly deduct if it's going to impact the project.

To improve security, CGImageCreate enforces parameter correctness on macOS 13 Ventura, iOS 16, iPadOS 16, watchOS 9, and tvOS 16. Passing an incorrect CGImageByteOrderInfo is no longer supported, and will result in images failing to load. (94855401)

CGImageCreate is being used in mac-playground, but it's not clear if the deprecation would affect anything. Any input guys? @filipnavara

Why is a CoreGraphics version of System.Drawing needed

To use the Cocoa driver for System.Windows.Forms, isn't writing and using a XplatUICocoa in System.Windows.Forms enough? Why is a CoreGraphics version of System.Drawing introduced?

Thanks

Dark Mode in macOS Mojave

Just wanted to note that dark mode looks really bad. I don't really think there's too much you can do about this given the purpose is to replicate WinForms, other than forcing default colors that match the light defaults. The NSRequiresAquaSystemAppearance plist key can be used to opt-out of dark mode for the app as a whole, but it sounds like that approach is only supposed to be a temporary work-around.

I know you mentioned somewhere at some point that you don't intend to support this other than your own needs, but I thought it was worth having this problem documented. I may eventually look into the problem myself but it's not a priority in the near future.

Mono.WebBrowser implementation

Is there any possibility to implement Mono.WebBrowser on macOS?

I have tried to build mono/gluezilla manually on macOS, but it seems not working properly when invoking gluezilla_bind().

Mouse capture implementation question

Something else that I noticed...

UngrabWindow in XplatUICocoa.cs includes these lines

if (LastEnteredHwnd != IntPtr.Zero && LastEnteredHwnd != grabbed)
{
	var lparam = IntPtr.Zero; // TODO: should contain mouse coords? See WindowsEventResponder.TranslateMouseEvent()
	var wparam = (IntPtr)(NSEvent.CurrentModifierFlags.ToWParam() | Mac.Extensions.ButtonMaskToWParam(NSEvent.CurrentPressedMouseButtons));
	SendMessage(grabbed, Msg.WM_MOUSELEAVE, wparam, lparam);
	SendMessage(LastEnteredHwnd, Msg.WM_MOUSE_ENTER, wparam, lparam);
}

This leads to a nested call of WndProc with WM_MOUSELEAVE when the mouse button is released (WM_LBUTTONUP) while captured.

My code was not prepared to deal with this. I'm not daring to suggest this is a bug in XplatUICocoa.cs that needs to be fixed. Only wondering if it should be PostMessage instead of SendMessage so that the button up message handling is completed before WM_MOUSELEAVE. I figured out this is what System.Windows.Forms.CarbonInternal.MouseHandler does in TranslateMessage.

Cannot handle ApplicationShouldTerminate in application without window

Some observations related to #2

When the application currently does not display any form ApplicationShouldTerminate in MonoApplicationDelegate.cs obviously cannot notify any window. It will return NSApplicationTerminateReply.Cancel to allow termination but the application has no chance to clean up before terminating.

I came up with this added code as a workaround

Message m = Message.Create(IntPtr.Zero, (int)Msg.WM_QUIT, IntPtr.Zero, IntPtr.Zero);
if (Application.FilterMessage(ref m))
	return NSApplicationTerminateReply.Cancel;

This way an application without a main form may install a message filter and handle ApplicationShouldTerminate.

The next observation is that with a dynamically top-level window ApplicationShouldTerminate is not received. I figured out that the behavior is caused by the SetModal call for the top-level window. Though I'm not sure why. The following change resolves the issue. But since I haven't really understood modal sessions I'm wondering if it might break anything else.

internal override void SetModal (IntPtr handle, bool Modal)
{
	NSView vuWrap = handle.ToNSView();
	NSWindow winWrap = vuWrap.Window;
	IntPtr session;
	if (Modal)
	{
		if (winWrap.ParentWindow == null)
		{
			winWrap.Center();
			ModalSessions.Push(IntPtr.Zero);
		}
		else
		{
			session = NSApplication.SharedApplication.BeginModalSession(winWrap);
			ModalSessions.Push(session);
		}
	}
	else if ((session = ModalSessions.Pop()) != IntPtr.Zero)
		NSApplication.SharedApplication.EndModalSession(session);
}

Are the suggested changes good enough for a pull request or do they not make sense?

Where is MonoMac.dll from

I see the MonoMac.dll in root directory and wonder where it is from?

I see two related projects below, is it related with these two projects?

NuGet restore: MSB4184: The expression "[System.IO.Path]::GetDirectoryName('')" cannot be evaluated

I performed the following steps so far, in order to attempt to build mac-playground:

I installed a fresh macOS Big Sur on VMWare
I installed the latest Visual Studio for mac,
I could not open the solution until I installed the latest .NET 6 preview SDK
Build failed saying there is no Xcode so I created an Apple ID, downloaded and installed Xcode, too
The Xcode path then was wrong, finally I managed to find out how to fix it in Preferences

Now I can build the System.Private.CoreLib project but nothing else. The build fails with NuGet packages need to be restored... but it is unable to restore the packages:

/usr/local/share/dotnet/sdk-manifests/6.0.100/microsoft.net.sdk.macos/WorkloadManifest.targets(7,3) : error MSB4184: The expression "[System.IO.Path]::GetDirectoryName('')" cannot be evaluated. Invalid path
Unable to create package spec for project. '/Users/username/repo/mac-playground/FormsTest/FormsTest.csproj'

And I'm stuck here. How could I overcome this issue? Are there any further gotchas I need to know about?

Btw, I wish the short step-by-step guide in the README was a bit more detailed (feel free to use my points above). The second bullet point there says I need to choose "Xamarin - Debug" but I only have the regular "Debug"/"Release" options so I'm not even sure whether I reached the second step in the build process...

I'm new to this process on macos and can't figure it out how to proceed.
I'm using Visual Studio for Mac Community v8.9.2(build 0) on MacOS Big Sur 11.1 (for now).
Thank you!

Color.FromArgb does not work properly

Color aColor = Color.FromArgb(233, 233, 233);
Console.WriteLine("R = {0}, G = {1}, B = {2}", aColor.R.ToString(), aColor.G.ToString(), aColor.B.ToString());

The snippet of code above will output:

R = 227, G = 227, B = 227

The value of 233 is changed to 227.

What is the corresponding version in Mono of System.Windows.Forms?

I found in some cases there are issues if I build System.Windows.Forms with MACOS_THEME and it is good if building without MACOS_THEME, DataGridViewComboBoxColumn, for example.

I would like to know what is the corresponding version in Mono of System.Windows.Forms? So I can check some source of without MACOS_THEME against Mono source.

System.Drawing.Icon is partly incompatible with Mono's implementation

The program is
https://ppmforums.com/download.php?id=29787
It works fine with some layout glitches when used with Mono's implementation, but it won't run with sysdrawing-coregraphics, it will throw such an exception.
