I understand that MPlayer calls a "configurerequest" and for that reason, completely ignores the rules of my Window Manager in Archlinux, AwesomeWM and instead of being tiled, it floats. Is there anyway to stop this from happening?
Thanks!
You want to find the following code block, and change floating = false:
awful.rules.rules = {
...
{ rule = { class = "MPlayer" }, properties = { floating = false } },
...
}
The determine the class part, do the following in a terminal window:
% xprop | grep WM_CLASS
Then click on the window whose class name you are trying to determine. One of those wonderful UNIX things that you have to experience to believe.
It's also possible to toggle floating by pressing ctrl+Mod+space (in my case, and I think it's awesomes default setting, the windowskey is the Mod key)
I don't know anything about "configurerequest", and I think mplayer is just a normal window like any others.
When reading /etc/xdg/awesome/rc.lua, I found MPlayer is specifically configured to be floating.
Removing that configuration in rc.lua might help.

I started using fmt for printing recently. I really like the lib, fast, easy to use. But when I completed my conversion, there are ways that my program can run that will render with a bunch of additional newlines. It's not every case, so this will get a bit deep.
What I have is a compiler and a build manager. The build manager (picture Ninja, although this is a custom tool) launches compile processes, buffers the output, and prints it all at once. Both programs have been converted to use fmt. The key function being called is fmt::vprint(stream, format, args). When the build manager prints directly, things are fine. But when I'm reading the child process output, any \n in the data has been prefixed with \r. Windows Terminal will render that fine, but some shells (such as the Visual Studio output window) do not, and will show a bunch of extra newlines.
fmt is open source so I was able to hack on it a bunch and see what is different between what it did and what my program was doing originally. The crux is this:
namespace detail {
FMT_FUNC void print(std::FILE* f, string_view text) {
#ifdef _WIN32
auto fd = _fileno(f);
if (_isatty(fd)) {
detail::utf8_to_utf16 u16(string_view(text.data(), text.size()));
auto written = detail::dword();
if (detail::WriteConsoleW(reinterpret_cast<void*>(_get_osfhandle(fd)),
u16.c_str(), static_cast<uint32_t>(u16.size()),
&written, nullptr)) {
return;
}
// Fallback to fwrite on failure. It can happen if the output has been
// redirected to NUL.
}
#endif
detail::fwrite_fully(text.data(), 1, text.size(), f);
}
} // namespace detail
As a child process, the _isatty() function will come back with false, so we fall back to the fwrite() function, and that triggers the \r escaping. In my original program, I have an fwrite() fallback as well, but it only picks up if GetStdHandle(STD_OUTPUT_HANDLE) returns nullptr. In the child process case, there is still a console we can WriteFile() to.
The other side-effect I see happening is if I use the fmt way of injecting color, eg:
fmt::print(fmt::emphasis::bold | fg(fmt::color::red), "Elapsed time: {0:.2f} seconds", 1.23);
Again Windows Terminal renders it correctly, but in Visual Studio's output window this turns into a soup of garbage. The native way of doing it -- SetConsoleTextAttribute(console, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_INTENSITY);-- does not trigger that problem.
I tried hacking up the fmt source to be more like my original console printing code. The key difference was the _isatty() function. I suspect that's too broad of a question for the cases where console printing might fail.
\r is added because the file is opened in text mode. You could try (re)opening in binary mode or ignore \r on the read side.
As the title says, the height of my tabs is not increasing as it should, my code looks like this:
JTabbedPane jtp = new JTabbedPane();
JLabel iconInTab = new JLabel(new ImageIcon("myImage.png"));
iconInTab.setPreferredSize(new Dimension(100,80)); // is the size of my Image, I've also try to do this using getSize
jtp.addTab(null,new JPanel());
jtp.setTabComponentAt(0,iconInTab);
I've also try this using html but it did not work either:
jtp.addTab("<html><p><p><p></html>",new ImageIcon("myImage.png"),new JPanel());
with the first code the problem is not the change of the size horizontally (the width change correctly), the problem is only on the height, with the second code, if I add multiple lines inside the html code, the text appear incomplete (just show the middle line) (also the width behaves as expected, the problem is the height). . .
why is this happening? or how could I get this done?
Note: S.O.: Mac OS X 10.8.1
Solved!!! The problem was that the default UI over MAC OS X (com.apple.laf.AquaTabbedPaneContrastUI), you only need to change it to the basicTabbedPaneUI (or the one of your preference), in my particular case I need to extend this class (it was a pain in the *, because what I wanted was really complex) to get the look & feel that I was expecting, if you have the same trouble just do this before adding your tabs:
myTabbedPane.setUI(new BasicTabbedPaneUI());
Note: Checking the default UI of your TabbedPane, may solve many different problems.

I'd like to, basically, have a quick way to select a box (region of interest) in an image, and get geometry output in ImageMagick's format. I cannot see an easy way to do it with the default ImageMagick display viewer, so I'm looking for some API (and hopefully examples) to allow me to code my own viewer.
A bit of background: In ImageMagick • View topic - selecting a region of interest from command line (2008) it is said you cannot do it, however, there is display: ImageMagick - Region of Interest (2003?) which explains how to do it (but apparently it refers to an older version).
Anyways, this is how things look is you call display -size 300x500 pattern:checkerboard (pattern:checkerboard is built-in pattern image in imagemagick):
Once the "ImageMagick" display window is up, click on it; then Command menu shows - from it, choose /"Image Edit"/"Region of Interest..."; then can click and drag on the viewer display window. And you also get the geometry in upper left corner - but you cannot copy/paste it as text (so I've had to retype).
Also, display in command line mode takes up the terminal (linux - Make imagemagick's display exit at terminal, preserving the window (single instance mode) - Super User) - and I cannot see a way to force it to run in "single instance mode", such that I could issue filenames on the command line, and display would load them in the one and the same currently running instance.
Now, I've found Casting spells with ImageMagick - Image manipulation for programmers (2012), which mentions a MagickWand API; after some searching, I found on the imagemagick site:
ImageMagick: MagickWand, C API for ImageMagick
ImageMagick: MagickCore, Low-level C API for ImageMagick
ImageMagick: PerlMagick, Perl API for ImageMagick
ImageMagick: Magick++, C++ API for ImageMagick
So, my first thought was a script in Python - but apparently there is only a Perl API, which is fine.
However, what I need to code is basically a command line interface, which will start a display -like window process as a "single instance", and exit the terminal while passing parameters such as file name, -density etc to the window; the window would then react on mouse clicks, allowing selection of a crop geometry box (region of interest) - and finally, render the geometry string in a text box, so you can copy it. But as far as I can see, all the APIs are oriented toward performing the functions of the command-line convert.
So my question is - can any of these API's be used to program a display-like GUI; and do there exist any examples of a similar nature (preferably in a scripting language, but I'll live with C/C++) which can be pointed out?
Many thanks in advance for any answers,
Cheers!
Well, this turned out to be a bit of a pain, but I managed to put together a Perl-Tk script with ImageMagick API, that behaves like what I wanted: imgckdis.pl (code also below). Here is a screenshot:
Note that it can pretty much just display an image in hardcoded 400x400 px (although it may extend for bigger images) - there is no menus, no mouse interaction (scrollwheel zoom) - pretty much nothing :) The script only accepts one command-line argument - a file to be opened; but it can also understand ImageMagick specials like "xc:white" (the ImageMagick portion will even automatically render SVG files, as shown on screenshot).
But one thing it is capable of, is working in single instance mode: the first instance started becomes a "master", and draws the Tk window, and locks the respective terminal. Subsequent instances of the script, realizing the master instance is already started, will simply issue a command to the master to load a new image.
This "issuing a command to 'master'" turned out to be not so easy, as the collection of links below shows (as well as the revision notes in the online vesrion). I thought at first, that using interprocess-communication shared variables would allow me to store a "pointer by reference" to the master; and then allow the subsequent instances to call functions on it. Well, it seems that cannot be done - for one, Perl may discourage that - but even if you hop over all those checks, in the end you get a memory address which is not seen as in shared space, and so one cannot retrieve anything from it. Furthermore, the IPC::Shareable Perl package is possibly "guaranteed" only for integers and strings ?!
Nevertheless, the approach that finally worked is, as hinted, to have the "master" poll for changes in changed variables; and non-master instances to simply change this variable when they are called - and this approach seems to work... However, for a "real" application, one would then have to think of organizing quite a few of these shared variables..
Well, maybe one cannot still zoom and reposition the image, and draw a geometry rectangle - but, at least it's an example that can be demonstrated to be working (at least on Ubuntu) :)...
Hope this helps someone,
Cheers!

I am creating a WC_COMBOBOXEX on Windows Vista and adding strings to it, but they don't show up in the control. The same strings show up fine if I use the old WC_COMBOBOX with CB_ADDSTRING.
I am calling InitCommonControlsEx with ICC_USEREX_CLASSES and creating the comboboxex using CreateWindowEx with style WS_CHILD|WS_CLIPSIBLINGS|CBS_SIMPLE|CBS_SORT|CBS_HASSTRINGS (no extended styles). I am adding the strings using
COMBOBOXEXITEM cbem = {0};
cbem.mask = CBEIF_TEXT;
cbem.iItem = -1;
cbem.pszText = L"hello";
SendMessage(hWnd_, CBEM_INSERTITEM, 0, TOLPARAM(&cbem));
The combobox comes up empty but when I move the cursor up and down in the editcontrol/listbox, I see funny block characters sometimes.
Eventually, I want to add it as a CBS_DROPDOWNLIST to a rebar control but I read somewhere that comboboxex works a lot better in there than the old combobox.
Thanks.
From MSDN:
ComboBoxEx controls support only the following ComboBox styles:
CBS_SIMPLE
CBS_DROPDOWN
CBS_DROPDOWNLIST
WS_CHILD
So CBS_SORT and CBS_HASSTRINGS may be messing up the style bits.
Does it help if you send CBEM_SETUNICODEFORMAT?
This feels like it should be pretty easy but I can't find documentation on how to do this:
I just want Sikuli to type Ctrl+C to copy text to the clipboard.
type(KEY_CTRL+'c') doesn't work and neither does type(KEY_CTRL,'c').
Any suggestions?
Try using type("c",KEY_CTRL) instead.
I wrote a simple script which types a line in notepad, double clicks it to mark it and then ctrl+x ctrl+v it into the document again. Works great.
openApp("notepad.exe")
find("textfield.png" )
type("Some text")
doubleClick("theText.png")
type("x", KEY_CTRL)
click("theTextField.png" )
type("v",KEY_CTRL)
The following works in 0.9 and newer versions of sikuli
type('x', KeyModifier.CTRL)
Key objects are defined for pretty much all the modifier keys and num pad keys. Anyways, it should look something like this
keyDown(Key.CTRL)
type('c')
keyUp(Key.CTRL)
The usage of type() and the possible key names are documented here:
http://doc.sikuli.org/region.html#Region.type
http://doc.sikuli.org/keys.html#key-constants
As others have mentioned, use the following:
type('c', Key.CTRL) # Copy command
One point worth mentioning - do not use upper-case characters, i.e.:
type('C', Key.CTRL) # Does not copy, avoid this
I haven't looked into the Sikuli source code, but my best guess is that it implicitly sends this as Shift+C, which results in a different command entirely.
type('x', Key.CTRL) also works.
Also, make sure that NUM_LOCK is off. If NUM_LOCK is on, it can make anything with KeyModifier.CTRL or KeyModifier.SHIFT misbehave.
You can try next code:
keyDown(Key.CTRL)
type("c")
keyUp(Key.CTRL)
I had a requirement to automate a flash content. The following code worked for me.
These were the following steps I ahd to perform as a part of the automation:
Enter Username and Password
Click on Login Button
Click on the button which will navigate to the application
The challenge I faced was to focus on the Username and password which had no placeholders . Hence the focusing was difficult. So I used the CTRL keys to do this .
Pattern appLogo = new Pattern("C:\\images\\appLogo.png");
StringSelection userNameText = new StringSelection("username");
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(userNameText, null);//Copy the text into the memory
Screen s = new Screen();
s.find(appLogo);
s.click(appLogo);
s.type(Key.TAB);//I had to enter tab twice to focus on user name textbox
s.type(Key.TAB);
s.type("V",KeyModifier.CTRL);
StringSelection password = new StringSelection("password");
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(password, null);
s.type(Key.TAB);//I had to enter tab twice to focus on user name textbox
s.type("V",KeyModifier.CTRL);
Pattern loginButton = new Pattern("C:\\images\\Login.png");
s.find(loginButton);
s.doubleClick(loginButton);
The scenario is like i need to press say key E in my keyboard after finishing the test how to add this in the script in Sikuli IDE.
