I lightened the background to Munsell value N7. Marked the issue as [SOLVED]. Don't know how to do it in green. Later...

Thanks for sticking with me. I suspect the app will now look better on various themes that I cannot anticipate. I wonder if I lost a contract because the thing looked bad on the customer's computer. I will give some thought to changing the background value depending on context. The way I have been u...

For example, while painting, the artist can take a snap of the work in progress, and sample an area to see what "real" color of paint to mix. It can also be used to copy photos in oil paint.

I'm not sure what you mean by the big ugly. The background is that color of gray because I chose it. It's a mid-value neutral, that I chose to help reduce a kind of compensation that the eye/brain makes, called "simultaneous color contrast". It's the basis for a lot of optical illusions. T...

The dark gray around is because it's rendered in Windows Aero theme. Stuff underneath the frame is showing through, by (Microsoft's) design. To make it marginally worse (so to speak) the snipper tool only does rectangles, not frames with rounded corners. It looks fine. Probably it would not look so ...

I've been saying that for decades, possibly pre-Al.

Thanks for the help. Much ado about not much on my part. I think Shakespeare said that.

Viola! as they say in France.


What I was missing a minute ago was that I had to set properties in two places to get an embedded manifest, to wit, in the Linker properties and the Manifest properties. The error message is no more.

It looks fine to me. https://s10.postimg.org/s0fvc8ci1/fruits.png But then, I don't do a lot with it: Load images, resize them up and down, shrink wrap the frame around them. The purpose of the program is to sample pixels and show the colors in Munsell notation. In the image above, a place in the or...

You single-stepped through the code and are 100% sure that CreateToolBar() causes the messages? Yep. Single-stepped all the way into it. I am completely sure that the messages come from CreateToolBar. I would try to create the toolbar before creating any child windows and applying any sizer. I can ...

OK. You asked for it. :-) Sorry it's so hard to read. I haven't figured out how to change the font color in the code box. // (c) Copyright 2009, 2018 David B.Jones // All rights reserved. #include "stdafx.h" #include "MyFrame.h" #include "munsell.h" #include "text_...

I tried the toolbar sample. It does not show the error messages. However, it is quite the bowl of spaghetti. I have given up on finding "the difference". All I can say is that I am not doing anything that (to me) looks the tiniest bit fishy. And if it is a sin of omission, I haven't a clue...

What type of images do you use for the toolbar? It reports the errors before I add any images. What version of wx do you use? wx 3.1.1, but it has done this for years; What compiler/SDK? VS-2017, C++17, 10.0.16299.0 , but it has done this for years. What's your version of Windows you are trying it ...

This behavior has been around for a long, long time. It applies to the MS WIndows port, a.k.a. `msw`. Am I doing something wrong, or is there a bug in wxWidgets? I create a toolbar in the MyFrame::MyFrame constructor, when all else is done. tb = CreateToolBar(wxTB_HORIZONTAL | wxTB_FLAT, ToolBar); I...

image.ConvertAlphaToMask(gray, gray, gray);

Yessiree. That does the trick. Thanks much!

I hope this problem rings a bell with someone I updated a project from wxWidgets 2.8 x86 to wxWidgets 3.1 64bit. Using Visual Studio 2017, VC++17. The project worked well before. Now in some circumstances .ico files with transparent backgrounds are displaying the backgrounds as black. The main windo...
