Overview

Principle for generating a Java application with WINDEV

WINDEV allows you to generate a Java application without even knowing the Java language. The method for developing the application is identical to the method for developing any other WINDEV application.

When the WINDEV project is compiled, the windows and the WLanguage functions are automatically converted into Java.

Available WLanguage functions


AnimationXXX functions	TreeXXX functions	BinaryXXX functions	Drawing functions
Drag and Drop	EmailXXX functions	InXXXMode functions	WinXXX functions
FTP functions	Functions for managing strings	Functions for managing controls	Functions for managing dates and times
Functions for managing external files	HTTPXXX functions	HyperFileSQL functions HFSQL functions	Print functions
IniXXX functions	JavaXXX functions	ListXXX functions	Mathematical functions
MatXXX functions	MemXXX functions	MenuXXX functions	ClipboardXXX functions
SocketXXX functions	MouseXXX functions	SQLxxx functions	TableXXX functions
Thread, Event and Semaphore functions	TimerSys and EndTimerSys	URLXXX functions	XMLxxx functions
ZipXXX functions (only the ZIP format without password is supported)	Looperxxx functions

This list evolves very quickly. We recommend that you check the documentation for each function. The

logo indicates whether the function is available in Java as well as its limitations.

The filter of the online help

is used to view the functions available in Java.

Specific features

The following elements are not available in Java generation:

the components.
Note: The internal components are available in Java. If the internal component includes an analysis, this analysis will be ignored during the execution.
the use of Web services
the OLE Automation dialog
the use and generation of .Net components
the multiple inheritance
the dynamic compilation
the "GOTO" statement
the syntax used to specify the name of a base class in front of a method
Example: MyBaseClass::MyVirtualMethod
the external language
the reports. However, the print is available in WLanguage.
Versions 19 and later
You have the ability to print in PDF format in WLanguage.
New in version 19
You have the ability to print in PDF format in WLanguage.
You have the ability to print in PDF format in WLanguage.
the "popup" windows
the indirections are not supported by the local variables
several structures with the same name cannot be found in the same project (even if they are defined in different classes).
the management of RTF format
the UMC (User Macro-Code)

The skin templates of version 10 (and earlier) are supported by the Java applications.

The custom mouse cursors (".CUR" or ".ANI") are not supported in Java.

Styles: the following features are not available:

Clipping the windows.
Shadow for static controls.
Transparency and animation of windows.
Some fonts specific to Windows may not be supported in Java (a default font will be used).
Font attributes: underlined and struck out.
Resizing the combo boxes.
Using the skin template of the project on system windows.
The buttons cannot have a multiline caption.

The Vista styles are available in Java.

Image formats

The following image formats are supported in Java: JPEG, PNG, GIF, BMP.

Related Examples:

Training (WINDEV): WD JavaMail

[ + ] This example is a Java example used to create an applet.
This applet can then be used in an Internet page.
This applet enables you read and send emails.
In this project, a second configuration enables you to manage a "Standard" Java application (.jar).
To generate the Java applet and the "Standard" Java application, select "Workshop - Java - Generate the Java archive",
for each one of the two configurations of project.

Training (WINDEV): WD Managing the Java errors

[ + ] WINDEV enables you to develop Java applications without even knowing Java.
You benefit from the power and from the automated processes of the WINDEV environment.
One of the most useful automated processes is the automatic management of errors.
This example presents the operating mode and the implementation of the mechanism for managing the WINDEV errors.
Some illustrations allow you to understand the simplification performed when implementing this feature.
This project is configured to generate a Java archive.

Training (WINDEV): WD Java Chart Designer

[ + ] WINDEV enables you to create some Java applications without even knowing Java.
You program with a 5GL (WLanguage) and WINDEV generates the Java code.
The drawing functions of WINDEV are available in Java generation.
This example explains how to create charts with these drawing functions.
Three types of charts are presented in this example:
- the bar chart,
- the scatter chart,
- and the line chart.

Training (WINDEV): WD JAVA Calls

[ + ] WD JAVA Calls is an example containing two configurations of project:
- A "Windows Application" configuration that is used to create the executable of the application
- A "Java Application" configuration that is used to create the Java archive (.JAR) of the application
This example is supplied with a JAR archive named "JavaFunction" external to the application.
It presents the call to the methods of classes of this JAR archive via the WLanguage function named JavaExecuteFunction.
This example also explains how a memory table can be filled (identical in Java mode and in Windows mode)
