@ Samples and Descriptions

These are the sample scripts using VisualuRuby(temp-name) to understand what this project can do and how to use it.

Some of them use a console and Japanese text so that you might have to use ruby from console (don't use rubyw.exe) and add -Ks option to ruby.
Using console is not necessary for this project. You can use rubyw.exe without using console function "print", "puts" or "p" in the script.

INDEX

Basic

dw sample.rb / dw sample2.rb

dw sample of treeview and listview
Explorer like treeview and listview in two paned window.
This sample script accepts the argument for the top directory.

Example for using template is followed to the 4 dialogs,
dw Using tab control
dw using RichEdit
Displays formatted rich text. Now you can set the format of the text but it's very hard to retrieve it. Because it cannot be retrieved as RTF.
dw using tooltip
Assignes tooltips for each control. And the background color of tooltip is modified. Tooltip can be assigned on the area of window.
The tooltip for the button indicates how many times it is clicked.
dw using rebar
I don't know the name for this control. rebar? coolbar?
dw using scrollbars
Using vertical scrollbar and horizontal scrollbar as control. I don't know why "changed" event is fired twice.
dw ActiveX control
Using InternetExplorer component in the window. The ActiveX controls must be known its ProgID and specified in the script. The events are also specified in the script with EventSink ProgID.

Event handling

dw event handling of grand-child's event
This is the same layout window of the last window in sample of resizelayout manager. VRPanel send the button event to its parent.
dw capturing key inputs by subclass-ing
Captures WM_CHAR to the edit control.
Also you can enum windows' message handling window.(useful for debug?)
dw forwarding events
The events from the control on a Panel or Groupbox is forwarding to the parent of that Panel or Groupbox.
Defines a Panel as a control contains a button and an editbox, and make it on a Form. The event from the button is handled on the Form.
dw arrayed control

The window has 2 VREdit and the focused one is changed color.

Automatic layout

dw Three windows using resize layout manager
screen capture
dw sample of resize grid layout manager
grid layout manager virtually makes grid on the window and arranges the controls on the grid.
Additionally prints current time on the titlebar caption in idle time.
dw sample of two paned window
You can move the separation line.
dw using layout frame
layout frame is like resize layout manager but it is not resized automatically by window resizing.
This can use only the specified area instead of all client area and can be used in nested style.
In this sample, VRResizeable captures the window resizing and resizes the outer layout frame by its size.
dw using paned frame
Classes for 2-paned or many-paned window. These can use in combination of paned frames to implement many-paned window. This script makes 4-paned window.
This is a kind of layout frame that described above, so that these classes do noting with window resizing by itself.

Drawing

dw GraphExplorer(exaggerated name)
Mathematic function graph is drawn in the upper side of the window. And on the downside the buttons are layouted to move the view of the function.
This window is sensitive its resizing and re-draws the graph according to its window size. If you modified @graph.xstep to larger number, the drawing will get faster.
screen capture
dw sample of offscreen bitmap (Memory DC)
You can draw lines by cliking the white area. The color and the width of the lines can be changed. This doesn't make original window class, so background color is default gray. This causes some blinking.
Didn't you make this kind of programs on basic or another old languages?
dw font changable clock
You can change the font for displaying the time by font select common dialog.
This sample creates original window class.
dw owner-drawn button
dw using priner

Shows text files contents with dropping files on the window.
On Win9x, over 64KB file is not acceptable because of the limitation of the edit control.

Before running this script, run Netscape.
The Netscape is navigated to the URL you select in the combobox.
dw DDE-execute server and its client.
