Xojo-Intro implements a simple way to build step-by-step tutorials in Xojo destop applications.

The equivalent for xojo web framework 1 is here -> https://github.com/VanDerLars/xojo_intro_js/

This library _currently_ **only** works on MacOS, since Xojo on Windows doesn't allow to draw semi-transparent controls.

I haven't testet it on a Linux Distro, so this could maybe someone report here.

Also, if you have Ideas to implement semi-transparent controls on Windows with Xojo - a hint or a pull request would be welcome.

Multiple step intros provide a simple UI to step-by-step describe your controls and functionalities.

1. copy the folder "Intro" into your project
2. Drag the class Intro->Classes IntroHandler onto your Window
3. Add in the window open event your steps (code see below)
4. Call your intro with Self.introHandler1.start

SampleCode:

Sub ShowMultipleIntro()
  // you can use every regular Control (which inherits from RectControl)
  Self.introHandler1.addStep(New introStep(Self.ComboBox1, "Combobox", "The combobox combines a textarea and a listbox"))
  Self.introHandler1.addStep(New introStep(Self.GroupBox1, "Groupbox", "Groupboxes are used to group multiple controls"))
  Self.introHandler1.addStep(New introStep(Self.PushButton1, "PushButton", "This is a button which fires some code."))

  // you can also use a Window
  Self.introHandler1.addStep(New introStep(Self, "Window", "Windows are the basic user interface structures where you can place your controls onto"))

  // also embedded ContainerControls are possible
  Self.introHandler1.addStep(New introStep(Self.TestContainer1, "ContainerControl", "ContainerControls are structures to be embedded into a layout. You can nest Controls."))

  // and also controls inside embedded ContainerControls
  Self.introHandler1.addStep(New introStep(Self.TestContainer1.Label2, "Nested Controls", "With this library you can even focus on controls which are placed inside Containers."))

  // And new: You can also highlight multiple controls at once, by using an array of controls:
  Var rArr() As RectControl
  rArr.Add(Self.ComboBox1)
  rArr.Add(Self.PushButton2)
  Self.introHandler1.addStep(New introStep(rArr, "ControlArray", "You can also highlight multiple Controls at once"))

  Self.introHandler1.start
End Sub

Single steps simply show your description next to your control.

Sub ShowSingleStep()
  Var d As New introStep(GroupBox1, "hallo", "yay")
  d.showSingle
  
End Sub

See the test project, this should give you everthing you need.

you have the following options, which can be set in the introHandler class over Code and UI and in the introStep class over code as well:

• closeStepByClickOnBackground True/False Indicates weather the intro is canceled by clicking on the background.
• useOwnColors True/False Indicates weather your own colors are used or the standard ones
• backgroundColorBackground color The color of the background which highlights your controls. Make sure you use a semi transparant color
• backgroundColorMessage color The background color of the message
• borderColorMessage color The border color of the message
• statusIndicatorVisible True/False Sets if the messages should show a status bar, indicating which step is currently shown.

• You can control the colors of your intros by altering the background color properties of the controls under Intro->UI
• The IntroHandler will always try to display the IntoContainer in a good position next to the highlighted Control. In case that there's not enough space on your layout, it will display a messagebox
• You can use all sorts of regular UI controls, which inherit from RectControl, but also Window and ContainerControl is possible
• Controls inside nested ContainerControls will work as well
• By making an array of RectControls, you can highlight multiple controls at once

current design:

Basic functions:

Resizing:

• Add ControlArrays to highlight more than one Control (currently only possible by using ContainerControls)
• Make use of the AnimationKit to smoothen the things a bit Canceled, because animation kit has no transperancy animations.
• Find another way to animate some things.
• More configurations of the whole thing would be a good thing.
• Resize the highlight area together with the window.
• Better resizing for some corner cases.
• Resizing of ControlArrays doesn't work well.

I don't plan to put much effort into this project. It was a fun little thing which I developed in three hours. But since I'm not really using Xojo desktop, I wouldn't make use of it in the future.

So feel free to pull the code, extend it and send your improvements in a PullRequest/MergeRequest. It's now up to you to make this basic thing better.
