Looking for a way of testing transparency?
A common requisite of an operating system is for the provision of a raw function sandbox, somewhere to mix, match and combine the effects of functions for the specific task on hand. In the attempt to render transparent forms, this script offers up a hodgepodge made from basic GUI elements, three functions along with their various conditions and flags:
- WinSet, ExStyle, ...
- WinSet, Transparent, ...
- WinSet TransColor, ...
- SetLayeredWindowAttributes
- UpdateLayeredWindow

With WS_EX_COMPOSITED set, all descendants of a window get bottom-to-top painting order using double-buffering. Bottom-to-top painting order allows a descendent window to have translucency (alpha) and transparency (color-key) effects, but only if the descendent window also has the WS_EX_TRANSPARENT bit set. Double-buffering allows the window and its descendents to be painted without flicker.

The window appears transparent because the bits of underlying sibling windows have already been painted. To achieve transparency without these restrictions, use the SetWindowRgn function.

<h1>The AutoHotkey Foundation</h1>
<h2>The Name</h2>
<p>
The name <q>AutoHotkey Foundation LLC</q> comes directly from the name of the software <q>AutoHotkey</q>. It is a non-profit LLC (Limited Liability Company) founded for this software.<br>Here is the <a href="https://autohotkey.com/certificate_of_organization.pdf">Certificate of Organization</a>.
</p>
<h2>Our Purpose</h2>
<p>
The <q>AutoHotkey Foundation LLC</q> was founded on April 24<sup>th</sup> 2014 in Indiana, USA. It was created in order to prevent monetization, ensure the continuing existence of the software <q>AutoHotkey</q> and naturally, continue the support for it. This foundation provides organizational, legal, and financial support for this software. It is a volunteer organization created <q>by the community, for the community</q>.
</p>
<h2>Who manages it?</h2>
<p>
The foundation's managers are Charlie Simmons (tank), Steve Gray (Lexikos) and Joachim de Fourestier (joedf) with guidance from Chris Mallett (the creator of the software <q>AutoHotkey</q>).
</p>
<h2>Our Mission</h2>
<p>
The tenets of this project will not change. We have and will continue to filter obvious wrongdoing. That said, we are not to be held responsible for any misuse. We shall not be financially liable for any misdeed. An LLC also serves to separate person from entity. Consider the following example: violating a license is not a criminal matter but there could be legal concerns if we appeared to have supported it. As such, the AutoHotkey Foundation LLC is not to be held responsible for any misuse of this product.
<br><br>
Many users were unhappy with the forum software changes and site administration policies, and when these opinions were voiced, entire threads were deleted as well as moderators were getting stripped of their privileges. Finally, we came here (ahkscript.org) and contacted Chris for his approval of creating a foundation. Here is a quote:
<div class="quote">
Having a real organization, especially a legal entity, would be quite an achievement. I'm glad you've done some preliminary research into it because it's far beyond anything I have any knowledge of. My response to your proposal is that as long as I wouldn't be responsible for the legal aspects or any other part of maintaining the organization (keeping it going), I wouldn't mind having some kind of guiding/suggesting position just the way you described, with some emergency authority in case things ever departed radically from the original spirit of the project (such as moving toward commercialization or bundling third-party, disreputable software with AutoHotkey).
</div>
<br>
We want a free and open, unaffiliated community that is transparent and respectful to all fellow users and developers. Here is our mission statement:
<ul>
<li>Provide highly useful Open Source Software (OSS) free of charge at the foundation owned domain.</li>
<li>Support the Software</li>
<li>Keep it Open Source</li>
<li>Not monetize the software or support site.</li>
<li>Have more than one person that can make changes to the site</li>
<li>Offer a web site to support the scripting software for windows
<ul>
<li>A support forum suitable to the sharing of knowledge for a scripting community.</li>
<li>Administration without monopoly</li>
<li>Solicits content improvements from the community</li>
<li>Hosts documentation that is freely available</li>
<li>Protects the community from SPAM, violent, derogatory, or any other abusive content.</li>
<li>Transparently identifies Moderators and Site Administrators</li>
<li>Supports users of multiple preferred languages when the user base is large enough to support it and adequate moderators are available.</li>
</ul>
</li>
</ul>
</p>
<h2>Our History</h2>
<p>
You may read about it in detail here: <a href="https://autohotkey.com/foundation/history.html">https://autohotkey.com/foundation/history.html</a>
</p>
<h2>Contributions</h2>
<p>
We are and will always be a volunteer organization. No one that is part of this will collect salary or fee. In the interest of staying with Chris's wish to not monetize <q>AutoHotkey</q>, from time to time we may need to open up and allow donations. Please note contributions are not only monetary. You may also contribute by developing code, submitting a bug fix, improving the documentation, helping other members, or even just filling a bug report. All funds or donations collected should and will be given to support this foundation and not to elicit any favour or rank.
<br><br>
You may donate through PayPal <a href="https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FXC8HB7XBTQJ6">here</a>.
</p>
<h2>Contact information</h2>
<p>
For any concerns, issues or any other problems, it is suggested to try the support forum first. If the subject matter is specifically about the foundation or its resources, you may also contact support (support[at]ahkscript.org).

Usage:
Select controls, if any, for the tester form, then adjust the TranspTester settings, and press Go. Drag the form around with the mouse in the titlebar area. When the form with an overlay is closed or cancelled, the button is clicked to show the underlay form for the purposes of comparison.
Esc mimics the Cancel button, but it also quits the program from any msgbox interrupt, F1 to reload either the test form or gui in focus.
Check Output Vars to output styles & attributes of the underlay form.
Check SO Example to handle the content offered at these Stack Overflow and AutoHotkey questions.
Check Use Setlayer to use the SetLayeredWindowAttributes function exclusively for Layering.
Notes:
In TranspTester, the underlay form is always used to render all of the desired content, the overlay form serves as a filter alone. It can be seen that applying effects to the overlay may not be necessary, and the inclusion of any other overlay form is for no other purpose than an extra TransColor pixel colour.
Enumeration of the ActiveX controls was intended for the retrieval of the child window styles, at least one codebank would play host for a better method. In most cases the transparency methods in the parent window override those of the children, but the validity of this assertion remains to be tested.
On W10, with no overlay form, the tester ActiveX form can be clicked-through on TransColor, with the titlebar also click-through when Layered. There is no click-through on a Transparent selection alone, because the wrapped SetLayeredWindowAttributes function does not use ULW_COLORKEY.
With image underlays, click-through occurs on Layered with Use Setlayer unchecked.
Although slow mouse strokes work well with the sliders on this machine, adjustments were made to the mouse speed in an attempt to address suspected small slider (+ interval) length along with mouse driver issues.
Wishlist:
Update the showing target form(s) dynamically with the settings on the main gui.
Because UpdateLayeredWindow is called throughout window moves, consider algorithms for varying colours and transparency factors to demonstrate the function's capabilities.
Consider the inclusion of GDIPlus functions.
