Share My Creation JavaFX application in WebPage.

After building a complex access-control, security Application in B4J and running like a charm for 3 years, I get the question to turn this in a Web-application.
This Application is that complex, that it is not possible to turn this, a easy way, in a Web-Application.
This means rewrite the hole application again for web.
I have found a way to let the application run in a Web Browser.

More info and Images follow

Hi,
yesterday i could successfully use my b4j app on an ios machine, ipad, android mobile. I see some small sizing problems, where the orginal size is not exactly the same as in webswing. I had small problems, my app did not close properly and so the webswing batch file was not stable.
I want to try to transfer webview on my qnap nas and try to use it together with the included webserver.
What i am looking for is what happens, when my webswing.bat file does not repond or stops working.

I have seen that on Linux the fonts are not the same as in Windows. This is not the problem of Webswing but Linux has not the same Fonts then windows.
About the size can you share some screenshots?
I also had to make some small adjustments for the Forms but solve this with a parameter for Desktop and Web. Like

Using Args for webswing:
 If Args(0).ToLowerCase = "webswing" Or Args(0).Contains("web") = True Then
   WebSwing = True
End If
You can use that like the image say.

The Size of forms is in the webpage 25px smaller then in WIndows Desktop.
Using many Forms can be a problem Titlebar is flickering.
There is a nice solution for that.
If you are using -1, -1 for height and width make height fixed.

:

The left one is show with webswing, you are right, this can be 25px.
I had the sizing problem with ios and tried to solve it to use the same css file. Your idea with commands is currently needed to solve them.

Hi all
I hope you can use WebSwing.
Now I have a question.
Because WebSwing is using the server Side, we can not reach the Local Client PC like folders and printers.
Have anybody solved this with JavaScript or something else ??

What you can do here is also a option.
Take your Form layout and add there your own TitleBar.
Change your MainForm.SetFormStyle("UNDECORATED")
Then you have solved your problem.

Thanks a lot for sharing this! I managed to run my Java 11.0.1 app in the browser in 5 minutes:

This one

in full screen with form decorations set to "UNDECORATED":

I followed this tutorial:

This is great, that's opening so many doors, it's incredible. Thanks a lot!

Create a nice Titlebar if needed and some functions what I can post here to move the form.

Move the Form with your own Titlebar and Form Undecorated:
Sub imgTitleBar_MouseClicked (EventData As MouseEvent)
    UserForm_CloseRequest(EventData)
End Sub

Private Sub lblTitleBar_MousePressed (EventData As MouseEvent)
    xMouse = EventData.X + lblTitleBar.Left
    yMouse = EventData.Y + lblTitleBar.Top
End Sub

Private Sub lblTitleBar_MouseDragged (EventData As MouseEvent)
    If isMaximized Then Return
    Dim jo As JavaObject = EventData
    Dim l As Double =  jo.RunMethod("getScreenX", Null) - xMouse - Main.MainForm.WindowLeft
    Dim t As Double =  jo.RunMethod("getScreenY", Null) - yMouse - Main.MainForm.WindowTop
    If l < 9 Then
        l = 9
    End If
    If l + ParentForm.Width > Main.MainForm.WindowWidth - 9 Then
        l = (Main.MainForm.WindowWidth - ParentForm.Width) - 9
    End If
    If t < 59 Then
        t = 59
    End If
    If t + ParentForm.Height > Main.MainForm.WindowHeight - 23 Then
        t = (Main.MainForm.WindowHeight - 23 - ParentForm.Height)
    End If
    ParentForm.Left = l
    ParentForm.Top = t -15

End Sub
You need to change the label and the image to your own names.

Using Webroot is also interesting.
Place there your own index.html and you will get this as background.
