Introduction Change easily the look of the Forms application.
Have a more « HTML » look.
Externalize the graphical information.
Add some missing functions.

10
Change easily the look of the Forms application Change the look of the GUIs’ elements Change the look of the Forms’ containers Draw gradient backgrounds, images, shapes and strings on the canvas Give table-blocks an « HTML » style December 2008
11
Externalize the graphical information Most of the graphical information is read from an external CSS file.
The painting is made at runtime by reading the required tags, then applying the changes through the Java Bean.
canvasEbay { type:canvas gradient-colors:r255g255b204,r255g255b255 gradient-vcycle:/2 gradient-hcycle:0 image1:/ebay.jpg,10,1,.8
image2:/ebay_line.jpg,30,74,.6,560,5 } tableHeaderEbay { type:header font-family: Arial; font-size:12 font-weight:bold frame-color:r250g83b12 inside-color:r255g204b0 font-color:r0g0b204 shade-color:r255g255b204 frame-width:2 frame-rounded-border: 10 transparency:.8
text-align:left text-align-offset:5 } December 2008
12
Have a more « HTML » look on table-blocks December 2008
13
Add a few new functions • Handle menus at runtime (add, enable, disable, show, hide, remove options).
• Handle frames at runtime (add, move, modify, hide).
• Play pre-loaded sounds.
• Receive external asynchronous messages.
• Draw texts anywhere on the screen.
• Display input dialog boxes.
• JColorChooser.
December 2008
14
What is it ?
a PL/SQL library That contains the functions and the procedures to read the tags from the CSS file and paint every object.
a JAR file That contains the Java Bean and the PJCs.
a CSS file That contains the tags’ sections.
December 2008
15
The PL/SQL library (laf.pll)
It contains the functions and the procedures needed to open the CSS file, read the tags from it, then perfom the drawing job through the associated Java Bean’s methods.
Open and read the CSS file.
PKG_LOOK_AND_FEEL.Open_Css()
Draw objects on the canvas.
PKG_LOOK_AND_FEEL.Paint_Canvas()
Decorate the given table-block.
PKG_LOOK_AND_FEEL.Paint_Block()
Set global properties for every GUIs widgets.
PKG_LOOK_AND_FEEL.Set_GUI_Properties()
December 2008
16
The JAR file (laf.jar)
It contains a Java Bean to perform all the graphical operations, and some PJCs to overload the common Forms widgets.
- The Java Bean allows to manage the following aspects:
Drawing shapes on the current canvas (images, lines, rectangles and strings).
Loading and playing sounds.
Dynamically handling menus - add, remove, enable, disable, show and hide menu options at runtime.
Dynamically handling frames – add, remove, modify, move, show and hide frames at runtime.
Display single or multi-line input dialog box.
Transform the Forms into a Socket Server, able to receive external asynchronous messages.
Display texts anywhere on the canvas during a given time.
Change fonts and colors for menu bar, window caption, status bar and tabs.
Pick a color from a JColorChooser.
Turn simple images into sensitive areas you can click on.
December 2008
17
The PJCs tend to give a more « Windows XP » look with the use of gradients.
They also extend the standard functions of the common Forms items: Buttons with mixed text and image, and mouse-on, mouse-over events.
Text items that allow sending events to the Forms (last key typed with key char, key code and key modifier) via the Tom Cleymans dispatching feature.
Blinking text items.
Hyperlink sort of text items.
Extended lists (multiple selection – sorted lists).
December 2008
18
The CSS file
It contains the different tags, grouped in five different section’s types:
type:canvas
That contains tags to decorate a canvas
type:title
That contains tags to draw a table-block title area
type:header
That contains tags to draw a table-block header area
type:body
That contains tags to draw a table-block body area
type:gui
That contains tags to manage the common GUIs elements December 2008
19
Title section’s tags Header section’s tags Body section’s tags December 2008
20
How it works?
The Forms side Read the CSS file, then decorate the elements by calling the Java methods -
Set_Custom_Property()
.
The Java side Use the Java methods to paint the Forms elements.
setProperty()
and
getProperty()

L&F Demo
December 2008
24
How to implement the L&F in a new module?
a Forms Object Library (laf.olb) That contains all the required objects to implement the L&F features.
a Forms template (LAF_TEMPLATE.fmb) To create a « fully equiped » new module from scratch.
attach the laf.pll library, compile and run !
Forms template demonstration
December 2008
25
How to implement the L&F in existing modules?
The JDAPI_LAF tool Written in Java to use the Oracle Forms JDAPI feature.
It Uses a XML configuration file to upgrade existing modules in a massive way.
It runs directly from the command line.
JDAPI_LAF demonstration
December 2008
26
How to maintain the CSS file?
The css_updater.fmb Forms’ sample dialog Updates any tag in any section of any CSS file.
Displays immediately any change done in any property.
