How can I custom specify, or force, the color of WS_EX_CLIENTEDGE [+E0x200]? I want a much more toned down color for it.
CustomColor := 000055
RequestToDisplay := "I want to change the color of WS_EX_CLIENTEDGE"
RequestTitle := "[REQUEST]"
GUI Request:FONT, s9 w1000 Q5, Verdana
GUI Request:COLOR, %CustomColor%, 000001

GUI Request:+LastFound +AlwaysOnTop -Caption -SysMenu
GUI Request:MARGIN, 0, 0
GUI Request:SHOW, x200 y300, %RequestTitle%

or you might be looking for one of the parameter specified in https://msdn.microsoft.com/en-us/library/windows/desktop/ms724371(v=vs.85).aspx
for instance, see COLOR_ACTIVEBORDER
and for autohotkey SetSysColors dllcall see https://autohotkey.com/board/topic/36724-setsyscolors-set-system-colors/
hope this helps

CP,
to my understanding, WS_EX_CLIENTEDGE is a window style (https://msdn.microsoft.com/en-us/library/windows/desktop/ff700543(v=vs.85).aspx).
to change the color of the edge that this window style produces, is an entire other question.
i would not know how to formulate this precise question.
but looking at your autohotkey code (AUTOHOTKEY changing WS_EX_CLIENTEDGE color), i see that CustomColor := 000055, to me it looks like an hexadecimal color value specified in a decimal way, that is without the 0x prefix (but that would be mandatory in C/C++)
SP.
in my C/C++ understanding one changes window's elements color calling SetSysColors() function see https://msdn.microsoft.com/en-us/library/windows/desktop/ms724940(v=vs.85).aspx for an example.
in that example, COLOR_ACTIVECAPTION is used to specify the window border element's color, it might be the one you are looking for.

I'm using a wxpython textctrl & would like to hide the caret. After a lot of searching it would appear that the best approach would be to simply change it's colour to white. However I can not work out how to do this.
I found the following info:
SetCaretForeground(fore)
Sets the foreground color of the caret. The parameter fore is a wxColour object, a #RRGGBB string, or a color spec like "white". Returns None.
from here: http://www.yellowbrain.com/stc/caret.html#setfg
The code for my current textctrl is below. Any help would be appreciated.
self.control = wx.TextCtrl(self, style=wx.TE_MULTILINE | wx.TE_READONLY | wx.HSCROLL)

You are using a wx.TextCtrl and the link you give is for a wx.StyledTextCtrl. These are completely different animals, and the wx.StyledTextCtrl has a lot more functionality than the simple wx.TextCtrl.
I don't think there's a way to set the caret color in an ordinary wx.TextCtrl.
I wanted to allow the Emacs cursor to move around freely outside of actual text (similar to virtualedit=all in Vim).
"Oh," I thought, "I'll just keep track of a virtual cursor and draw it to the screen myself."
But it turns out the actual native C drawing routines (such as draw_glyphs) seem to refer back to the buffer contents to decide what to draw (I could be wrong though).
My next idea was to make a giant overlay of all spaces so I'd have complete freedom where to put stuff. But an overlay only goes over ranges of actual text, so again, this does not seem to give me what I'm looking for.
Is this a reasonable goal without hacking the C code?
I believe the writeable area of a window is intrinsically limited to the buffer with which it is associated, i.e. you have to draw in an area where buffer content exists.
(One example of this limitation is the impossibility of drawing a vertical guide line in the 80th column to help the user identify long lines; currently the best possible implementation of such a feature is to highlight the "overflow" of each too-long line.)
You can do the same as what artist-mode does without adding spaces to the buffer:
when trying to place the cursor after the end of the line, just use an overlay with an after-string property which adds the spaces in the display without modifying the buffer.
Have a look at "artist-mode" (M-xartist-modeRET) - it allows you to draw in Emacs.
From the function documentation: "Artist lets you draw lines, squares, rectangles and poly-lines, ellipses and circles with your mouse and/or keyboard."
You can look at popup.el from the auto-complete package, which can pop up tooltips and menus and such at any position, including positions outside the contents of the buffer. Maybe that will show you how you can do it.
currently I produce dynamically this document with Python Report Labs… to produce pdf documents.
Now, I would like try to produce this document with Tex / Latex / ConTeXt…
I've some questions :
how can I make the layout ?
how can I make header background color ?
how can I define my custom title (with blue box) ?
what is the better choice for my project : Latex or ConTeXt ?
What package I need to use ?
geometry ?
fancyhdr ?
Have you some example ? some resource ?
Yesterday, I've read many many documentation… and I don't found a solution / example for my questions.
Some useful packages apart from the fancyhdr you already mentioned are:
titlesec for more control over your section titles
booktabs for more control over table layout
PGF/TikZ for the graphics in your document, i.e., the page turn effect in the corner and maybe the blue boxes (although that might be considered a bit overkill :))
memoir for more control over your document layout, but the package is more book-oriented than you need probably
koma-script might be a good alternative for memoir but I'm not familiar with it so I don't know about its weaknesses
This is list is not exhaustive and I am not experienced enough in this kind of typesetting meets lay-out stuff to be of much help, but these are packages that come to my mind given your problem :).
Using inputenc there shouldn't be a problem typesetting Russian text.
Maybe the actual process will be easier in ConTeXt, it is more oriented towards control over your typesetting but I'm not familiar with it.
Good luck!
I'd certainly do this kind of think in Context rather than Latex: Context permits grid layout, and allows you to define layers for putting text and other graphics on top of background graphics. But as Pieter says, you could try using TikZ to do this with Latex.
Unicode is no barrier to regular Latex or Context: with either, just specify that you want to use utf-8 as input encoding.
If you do use Latex, don't have headers or footers, and allocate no vertical space for them either.
With Context:
how can I make the layout? — Use grid layout.
how can I make header background color? — Use \setupbackground
how can I define my custom title (with blue box) ? — I don't understand what you want to do here.
Everything you need to do this, except grid mode and how to put graphics in the background, is documented in Context an excursion. Grid mode is explained in the Context manual. Layers are a bit tricky to get to grips with, but Layers in the Context wiki is a good place to start.
With titlesec and color packages use this in LaTeX head (before \begin{document})
\usepackage{titlesec}
\usepackage{color}
% Colors
\definecolor{textcolor}{rgb}{.90,.95,1}
\definecolor{boxcolor}{rgb}{.94,.97,1}
% Header style
\titleformat{\section}
{\color{textcolor}\normalfont\Large\bfseries}
{}{1em}{{\color{boxcolor}\rule{0.35cm}{0.35cm}}\quad}
to make the blue box and change header color, font and remove numbering.
I'm not sure how to ask this but here goes.
I draw a filled coloured rectangle on screen. The colour is in form of R,G,B
I then want to draw text on top of the rectangle, however the colour of the text has to be such that it provides the best contrast, meaning it's readable.
Example:
If I draw a black rectangle, the obvious colour for text would be white.
What I tried right now is this. I pass this function the colour of the rectangle and it returns an inverted colour that I then use for my text.
It works, but it's not the best way.
Any suggestions?
// eg. usage: Color textColor = GetInverseLuminance(rectColor);
private Color GetInverseLuminance(Color color)
{
int greyscale = (int)(255 - ((color.R * 0.30f) + (color.G * 0.59f) + (color.B * 0.11f)));
return Color.FromArgb(greyscale, greyscale, greyscale);
}
One simple approach that is guaranteed to give a significantly different color is to toggle the top bit of each component of the RGB triple.
Color inverse(Color c)
{
return new Color(c.R ^ 0x80, c.G ^ 0x80, c.B ^ 0x80);
}
If the original color was #1AF283, the "inverse" will be #9A7203.
The contrast will be significant. I make no guarantees about the aesthetics.
Update, 2009/4/3: I experimented with this and other schemes. Results at my blog.
The most readable color is going to be either white or black. The most 'soothing' color will be something that is not white nor black, it will be a color that lightly contrasts your background color. There is no way to programmatically do this because it is subjective. You will not find the most readable color for everyone because everyone sees things differently.
Some tips about color, particularly concerning foreground and background juxtaposition, such as with text.
The human eye is essentially a simple lens, and therefore can only effectively focus on one color at a time. The lenses used in most modern cameras work around this problem by using multiple lenses of different refractive indexes (chromatic lenses) so that all colors are in focus at one time, but the human eye is not that advanced.
For that reason, your users should only have to focus on one color at a time to read the text. This means that either the foreground is in color, or the background, but never both. This leads to a condition typically called vibration, in which the eye rapidly shifts focus between foreground and background colors, trying to resolve the shape, but it never resolves, the shape is never in focus, and it leads to eyestrain.
Your function won't work if you supply it with RGB(127,127,127), because it will return the exact same colour. (modifying your function to return either black or white would slightly improve things)
The best way to always have things readable is to have white text with black around it, or the other way around.
It's oftenly achieved by first drawing black text at (x-1,y-1),(x+1,y-1),(x+1,y-1),(x+1,x+1), and then white text at (x,y).
Alternatively, you could first draw a semi-transparent black block, and then non-transparent white text over it. That ensures that there will always be a certain amount of contrast between your background and your text.
why grey? either black or white would be best. white on dark colors, black on light colors. just see if luminance is above a threshold and pick one or the other
(you don't need the .net, c# or asp.net tags, by the way)
You need to study some color theory. A program called "Color Wheel Pro" is fun to play around with and will give you the general idea.
Essentially, you're looking for complimentary colors for a given color.
That said, I think you will find that while color theory helps, you still need a human eye to fine tune.
How do you determine the length of a string of text in Arial Bold font, and then center it in VB6?
We are not using a "label" or "picture box" to print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.
One way is to have a hidden picture box and setup the font specs of that picture box the way you want.
Then use the TextHeight and TextWidth methods of the PictureBox to take your measurements. The Units will be in whatever scalemode the Picture Box is set to.
If you are printing directly to the printer or form then just set your font FIRST then take your measurements.
To center it
MyText = "Hello World"
<displayarea>.FontName = "Arial"
<displayarea>.FontSize = 14
<displayarea>.FontBold = True
TextWidth = <displayarea>.TextWidth(MyText)
TextLeftCoordinate = <displayarea>.ScaleLeft+<displayarea>.ScaleWidth/2-TextWidth/2
<displayarea>.CurrentX = TextLeftCoordinate
<displayarea>.Print MyText
Substitute displayarea with whatever object you are using.
Based on your updated answer note that the hidden picture box suggestion isn't used to print. It is only get text measurement. However you are printing directly to the form so you just need to use the code example above.
I can't remember the specifics (it's been about 3 years since I last used VB 6), but there's a method on Form called something like "MeasureString". It takes the string, and measures it according to the font settings of the form.
Also, here's a comment posted by Jason Lepack in case I've misunderstood and over-complicated your requirements:
"Labels usually have an alignment property. If you set it to align to center then, regardless of the font face it should center in the label".
There are Win32 GDI functions you can invoke: see for example GetTextExtentPoint32 at http://msdn.microsoft.com/en-us/library/ms534223(VS.85).aspx
Your best option may be Form.TextWidth, which appears to return the width of a string in twips. I've just taken this approach in order to dynamically size a button based on the length of the label that needs to appear inside it.
There is also a corresponding function called Form.TextHeight which would allow you to do the same thing in the vertical dimension.
Make sure that you set the Font property of the form to match the Font property of the control you're intending to measure the text for, otherwise you'll get incorrect results.
