I have been playing with writing an application using Scala, with its API defined in ScalaFX, which wraps the powerful JavaFX library. For simple exercises, coding the UI by hand was enough. But for more complex forms, I began using the JavaFX Scene Builder tool.
Fortunately, others have blazed this trail, and there are fairly stable ScalaFX and ScalaFXML libraries available.
Using the Scene Builder tool, I laid out my form and included a ListBox to hold possible gender selections.
The Scene Builder tool generated fxml code such as: <AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="208.0" prefWidth="275.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1"> <children> <Label layoutX="14.0" layoutY="30.0" text="Name" /> <Label layoutX="14.0" layoutY="71…
One thing I love about working in Information Technology is the opportunity - the NEED - to constantly learn new things. If a week goes by in which I have not looked up something on StackOverflow or other message boards, I start lobbying my team for more challenges.
This week, I learned the power of running "SCHTASKS.exe" from a command-line script for a remote server in a Microsoft Windows environment.
In a nutshell, it is the command-line interface for the Windows Task Scheduler, and allows you (or a system administrator) to create, change, run, query, terminate, and delete scheduled tasks on a work-station, either the local one or a remote one.
Not all of the features are available in older versions. In my scenario below, this was relevant as the local computer will be a Windows 8 machine, and the remote server is, shall we say, a muc…
I have a project that is building a system in Scala. Its GUI is being defined using the ScalaFX system, which is a thin layer that delegates to the underlying JavaFX tools, components and features.
The application was running with a fine-looking GUI in early testing, but all the builds were being driven by the IDE. For various reasons, we wanted to migrate the build to the SBT system.
But upon launching with $ sbt run
we would get entries like this in the console: [info] Running StartHere May 21, 2016 8:50:28 PM com.sun.javafx.css.StyleManager loadStylesheetUnPrivileged WARNING: Resource "com/sun/javafx/scene/control/skin/modena/modena.css" not found.
The application would compile without issue and would run correctly, but looked terrible. For instance there would be no edges visible for buttons or for text box input fields.
Obviously, a dependency was missing from the build.sbt file. It was easy enough to add, with a line like the following: unmanagedJars in Compile += Attribute…
