Introduction to javafx scene builder 1.0 Developer Preview

1. the javafx scene builder 1.0 Developer Preview is a design tool for the javafx platform it can assist you with quickly prototyping an application with interactive user interface that is linked to the application logic. you simply drag and drop graphical user interface (GUI) components onto a javafx scene and the fxml source code for your layout is automatically generated. javafx scene builder is available for the Windows and Mac OS X platforms.

In short, it is the visual development of the javafx interface. The software can automatically convert the configured interface into a fxml file.

3. Currently, this version of javafx scene builder still has many known problems, such:

(1) The main limitation is that javafx scene builder is unable to load fxml files that reference Custom User classes.

The main drawback is that fxml files that reference user-defined classes cannot be loaded.

(2) The tableview UI control is supported in javafx scene builder Developer Preview release, but with the following limitations:

• You can not add a table column component to a table View Control Using javafx scene builder. The library panel currently does not list the table column object.

• It is currently not possible to reorganize or re-parent the table columns using javafx scene builder.

The tableview control can be used, but has limited functions. You cannot add a column in javafx scene builder. You cannot reorganize columns in a table.

(3) There is no internationalization support available with the javafx scene builder developer release. It is only localized in English, regardless of the locale of the user's operating system.

It does not support internationalization! This is indeed, I have tried it and there will be some Chinese garbled characters. The solution is to use resourcebundle! Use a pure English name in the fxml file, and then define the corresponding

The properties file maps the corresponding key-value pairs in the file, but this is still a bit of trouble.

(4) a ui component becomes unselectable when the disabled and mouse transparency flags are set.

Description: When you check the disabled or mouse transparency flag of a UI component, that component becomes unselectable in the content panel.

If you select the disabled or mouse transparency flag for a UI component, the component cannot be selected in the content panel.

(5) CSS related errors are not displayed when loading a fxml file.

Description: When you load an fxml file that contains invalid CSS files, any CSS related error messages are not displayed in the message bar.

Workaround: in order to see the error message, you need to force a CSS update on the layout. for example, you can edit the CSS file and save it. if some errors are detected, then an error message will be displayed in the message bar when javafx scene builder does a refresh of the CSS rules.

CSS errors are not displayed when a fxml file is loaded. The solution is to edit the CSS file and save it.

(6) popup control elements that are part of that UI component do not inherit from a parent container's style sheet nor from any inline styled declarations made to the parent container.

Description: If you assign a CSS file to the style sheets property of a parent container (E. g: Root anchor pane), the rules in that CSS file are not applied to the popup control elements that are associated with the container's Children elements. inline styled declarations inherited from the parent container are also not applied to the popup control elements of the children objects. popup control objects are context menu and tooltip.

Workaround: directly work with the style property of the context menu and tooltip to set the CSS styling rules.

A pop-up control element is a type of UI component that does not inherit its parent component style, and is not affected by the style declaration in the row. the pop-up control elements include context menu and tooltip.

The solution is to manually set the style attribute for the pop-up control.

(7) exception messages thrown by the CSS parser contain invalid lines and column numbers.

Description: if some CSS related error messages are displayed in the message bar (e.g. invalid Syntax, invalid content), you will notice that the numbers appear meaningless. these numbers are supposed to refer to the line and column numbers to help locate the source of the errors. do not use these line and column numbers because they are not valid.

When the CSS parser throws an error, the rows and columns in the information displayed on the interface are useless. They are incorrect.

(8) The-Fx-font property is not inherited from the parent container.

Description: If you set the-Fx-font property on a container element, such as an anchor pane, its contained children elements do not inherit from that styling property. if the font rule impacts the font size, note that the boundaries of the children elements are affected (children becomes bigger or smaller ).

Workaround: set the-Fx-font directly on the target child element instead.

Note: The-Fx-font attribute will not be inherited from the parent container!

(9) Rendering of some parts of javafx scene builder UI may not be properly refreshed.

Description: On rare occasions, javafx scene builder may become unresponsive. for example, the focus on a participant panel is not being displayed even though the focus has been gained, or the selection of an element in the content panel is not updated when the selection has changed.

Workaround: resize the Inspector panel.

In some cases, javafx scene builder may become unable to respond (this is indeed, sometimes well done, and suddenly the right panel does not respond, it is usually when the CSS style is deleted or modified, or a component is suddenly deleted). The solution is to reset the Panel size. It does not seem to work. I usually turn it off and restart it!

 

In short, javafx scene builder still has many problems. One of the major problems I have found is its CSS style. Sometimes it is no problem to define a style for a component, however, if you add a style class, an error is reported. An error is reported in the program! This is even true if CSS files are loaded with scene! Weird... Tangle... Continue !...
