I'm running this in a folder with main.qml:

$ qmlscene main.qml
qmlscene: could not find a Qt installation of ''

Then I checked

$ qtchooser -list-versions
4
5
qt4-x86_64-linux-gnu
qt4
qt5-x86_64-linux-gnu
qt5

... and tried

$ sudo qmlscene -qt=qt5-x86_64_linux-gnu main.qml
qmlscene: could not find a Qt installation of 'qt5-x86_64_linux-gnu'

I am installing the default QT on the base yum repos (version 4: sudo yum qt qt-devel. I can see that it includes the bin (in /usr/lib64/qt4/bin) and the includes (in /usr/include/Qt , /usr/include/QtCore). I am not sure where the lib files are, or if they are named in the same format as the qt3 lib directory (/usr/lib64/qt-3.3/lib/libqt-mt.so.3). Are these files in the same naming convention i.e. libqt-mt.so.4, or what would I be looking for here?

I made a terminal by binding bash with *QProcess*:

++
// c++ in Qt4.8.7 on CentOS7
process_ptr->start("bash -i", QIODevice::ReadWrite | QIODevice::Append);
// With the "-i" option, interactive bash is able to display the *prompt*

Commands are entered through *QCmdLine*, fed to *QProcess*, and the output is printed to *QPlainTextEdit* And I have merged the standard output channel with the standard error channel:

++
process_ptr->setProcessChannelMode(QProcess::MergedChannels);

The problem is: the command prompt(set by PS1) in *QPlainTextEdit*, which is used to display stdout or stderr, is messy. **Specifically, the content printed in *QPlainTextEdit* is as follows:**

^[]0;eng@hostname:~^G[eng@hostname 15:36:41 #17 ~]$
ls

Desktop

^[]0;eng@hostname:~^G[eng@hostname 16:05:12 #18 ~]$
echo $PS1
[\u@\H \t #\# \W]\$
^[]0;eng@hostname:~^G[eng@hostname 16:05:35 #19 ~]$

^[]0;eng@hostname:~^G[eng@hostname 16:05:36 #19 ~]$

And I have set PS1 as

PS1="[\u@\H \t #\# \W]\$ "

It looks like the second half of the command prompt

[eng@hostname 15:36:41 #17 ~]$

is what I set up correctly via PS1. **Now I don't know how to get rid of the first half**

^[]0;eng@hostname:~^G

, where

^

denotes the ASCII control character "ESC" and

^G

denotes the ASCII control character "BEL" I've researched the concept of *tty* for this issue: my practice of binding a fixed bash via *QProcess* bypasses line discipline and pty, in other words input and output content is *written/read* directly to the bash process without going through line discipline and pty(Here's the link, it might be useful: [tty/pty ) At the moment I'm not sure which module I should look at to locate the root cause of the problem: standard output/error channel redirection, the underlying principles of bash, *QPlainTextEdit* in Qt, etc. Thank you very much for your valuable thoughts or solutions!

So, I have a .py file: from PyQt4.QtGui import * from PyQt4.QtCore import * When I'm executing it - I have this error message: Traceback (most recent call last): File "kek.py", line 1, in from PyQt4.QtGui import * ModuleNotFoundError: No module named 'PyQt4.sip' I've tried to install **sip** itself, I've installed **Qt4**, **PyQt4** and it doesn't works. Help me, guys

For the package GeoGebra 5, the text of the menu bar looks bad, with a strange (and unwanted) font. This is the normal, good look of the menus of other programs: This behavior is new. It's happening since around one week ago. Before this issue, I was tired by a poor appearance of my desktop: it looked with an old-fashion; almost all the fonts of the desktop looked no so well. So, I followed this suggestion: https://forum.manjaro.org/t/better-font-settings-in-easy-way-xfce-and-gnome/24319 However, I didn't make the step for Qt configuration. My system works with Qt4. Maybe this is the reason for the trouble. Today, I tried with the Qt4 configuration, font substitution. However, I don't know how to manage rightly this setting. I guess that the shown font is Abydos (it appears in the Qt4 font setting window, substitution area; it's exactly the first item in my fonts list). I have tried too: - changing some options in Setting tools Appearance and Windows Manager - uninstalling (https://askubuntu.com/questions/151941/how-can-you-completely-remove-a-package , post of user2777677), deleting the geogebra and GeoGebra folders of my .config directory, and reinstalling GeoGebra 5 without fixing the issue. My system: Debian 9, Xfce, 64 bits This questions could be similar to my case: - https://unix.stackexchange.com/questions/126281/weird-bug-with-xfce4-menu-panel-font-very-small - https://unix.stackexchange.com/questions/443065/fix-for-ugly-fonts-in-programs-like-keepassxc-or-nextcloud-on-antergos-with-gnom

I am using Xephyr to run applications as another user, while being logged in as primary user. Most applications work fine in Xephyr, except qt4 based. Specifically: electrum ipython qtconsole qbittorrent The above applications work when started in normal X server, but when I start them in Xephyr, I only see the window frame, but it is blank. How can I fix this problem ? My OS is Debian Wheezy and version numbers are: xserver-xephyr 1.12.4 libqtcore4 4.8.2 Here is how I start my Xephyr session: Xephyr :1 -screen 1920x1080 -nolisten tcp -reset -terminate >/dev/null 2>&1 & terminator --execute su - user2 -c 'DISPLAY=:1 startlxde >/dev/null 2>&1 &' **UPDATE** I have tested with XFCE4 and have the same problem. QT4 applications still don't work, I get a blank window. As example, see how qbittorrent window loks like:

I have created an application through Python that has library dependencies on Qt4, pyqt4, pyqtgraph etc. This application is based on Raspberry Pi, I have developed and finished it on the platform. I want to configure Raspberry Pi to only run that one single application. When I power the Raspberry Pi, it should not go to desktop but run the application (eventually only use necessary packages,library etc). I have been looking around on different forums on how people do it, but it's not what I'm exactly looking for. There are also different solutions but it's just a bit confusing, that's why I'm here asking for advice/tips on how to implement that. So far I've tried sudo /etc/profile and at the end of that file I call python3 /home/pi/test.py where I execute my application. But I get X cannot connect Server error and Virtual Keyboard Florence is not really registering the button pressed.

I want to install the Wing IDE for python. When I executed it, dpkg showed me some qt packages that were not installed.

I'm using a VirtualBox machine (32 bit) to build BLFS to comply with the Linux Standard Base (all the packages mentioned in the book (http://www.linuxfromscratch.org/blfs/view/7.8/ ), with *required* and *recommended*, but trying to avoid *optional* packages). As the title says, I can't get BLFS 7.8 to completely build Qt 4.8.7. According to the BLFS 7.8 book, it's supposed to build the following: Installed Programs: assistant, designer, lconvert, linguist, lrelease, lupdate, moc, pixeltool, qcollectiongenerator, qdbuscpp2xml, qdbus, qdbusviewer, qdbusxml2cpp, qdoc3, qhelpconverter, qhelpgenerator, qmake, qmlplugindump, qmlviewer, qt3to4, qtconfig, qttracereplay, rcc, uic3, uic, xmlpatterns, and xmlpatternsvalidator Installed Libraries: libQtUiTools.a, libQt3Support.so, libQtCLucene.so, libQtCore.so, libQtDBus.so, libQtDeclarative.so, libQtDesignerComponents.so, libQtDesigner.so, libQtGui.so, libQtHelp.so, libQtMultimedia.so, libQtNetwork.so, libQtOpenGL.so, libQtScript.so, libQtScriptTools.so, libQtSql.so, libQtSvg.so, libQtTest.so, libQtWebKit.so, libQtXmlPatterns.so, and libQtXml.so, and several plugins under /opt/qt4/imports and /opt/qt4/plugins It builds all the libraries, but not all of the programs: qdbuscpp2xml, qdbus, qdbusviewer, qdbusxml2cpp, qmake, xmlpatterns, and xmlpatternsvalidator are not built. Since most of the programs left out have dbus in their names, I checked systemctl and the result is the following: UNIT LOAD ACTIVE SUB proc-sys-fs-binfmt_misc.automount loaded active waiting

Basically, I have a change to be done in /usr/src/qt/src/src/gui/kernel/qclipboard_x11.cpp There is a 10s timeout that causes apps to hang on shutdown (search the file for the word "reasonable"). Not very reasonable, in fact. For illustration, this is what I want to mitigate - I can't open another instance of Okular until the 10 seconds timeout ends. okular(9173) Okular::Utils::realDpiY: Pix: 1080 MM: 285 okular(9173) Okular::Utils::realDpiX: Pix: 1920 MM: 508 okular(9173) Okular::DocumentPrivate::openDocumentInternal: Output DPI: QSizeF(96, 96.2526) ... (window is closed) ... (10 seconds later) ... QClipboard: Unable to receive an event from the clipboard manager in a reasonable time Here I should be able to fix it: XEvent event; // waiting until the clipboard manager fetches the content. if (!X11->clipboardWaitForEvent(ownerId, SelectionNotify, &event, /*HERE->*/ 10000, true)) { qWarning("QClipboard: Unable to receive an event from the " "clipboard manager in a reasonable time"); } I've changed this to 3 seconds, which should be much better. How to make the changes apply? Is there some makefile to run to rebuild Qt from these sources, or am I doing it completely wrong? I assume there's some qt library object file that needs to be rebuilt, but I can't find a way to do it. Thanks. btw. it's Arch install with Xfce, if it's relevant in any way

I'm trying to use a dark Gtk+ theme, and everything goes fine with native Gtk+ apps, and well, only with Gtk+ apps. I mean, wxWidgets and Mozilla's apps looks terrible, if not counting unreadability (see screenshot below). Rendering Gtk's buttons and fonts in Qt apps looks bad too. I've learned Mozilla's apps could improve readability (text on light background become readable **but** text on dark background becomes hard to read) by adding this to gtk-2.0/gtkrc: style "moz" { text[NORMAL] = "#000000" base[NORMAL] = "#FFFFFF" } class "GtkInvisible" style "moz" apwidget "GtkInvisible" style "moz" So I came out with this solution: start these apps with a 'fallback' light Gtk+ 2 theme (let's say Adwaita). But launching with something like GTK2_RC_FILES=/usr/share/themes/Adwaita/gtk-2.0/gtkrc could change gtk's PNGs (like buttons and checkboxes), **not** the color scheme: I noted that doing this, it returns some warnings, e.g.: $ GTK2_RC_FILES=/usr/share/themes/Adwaita/gtk-2.0/gtkrc audacity (Audacity:12322): Gtk-WARNING **: gtk_disable_setlocale() must be called before gtk_init() $ GTK2_RC_FILES=/usr/share/themes/Adwaita/gtk-2.0/gtkrc icedove (process:13204): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed With Qt(4) apps, I tried to use a native good-looking theme like Breeze, but couldn't find a way to choose it after installing (I had no luck using qtconfig-qt4). Here are some of my software versions (I'm using Debian testing): - Gtk+ 2: 2.24.28 - Gtk+ 3: 3.16.6 - Qt4: 4.8.7 - wxWidgets: 3.0.2 (Audacity's version is 2.0.6) - Iceweasel (Firefox): 38.1.0 - Icedove (Thunderbird): 31.7.0 Does anyone know how to solve this problem? I would be really glad to see any answer, even if it's specific to only one application.

I have downloaded a QtCurve theme. I do not use KDE, I use a standalone WM (awesome). How do I change QtCurve style/theme via config file editing? Which config file contains this setting?

I have installed every possible package that could have to do with QtCore (I think), but the QtCore library is nowhere to be found. Not in /usr/lib, not in /usr/local/lib, not in usr/include... you get the idea. Still, CMAKE gives the location of QT_QTCORE_LIBRARY_RELEASE as QT_QTCORE_LIBRARY_RELEASE-NOTFOUND and since it doesn't show up where I look, I can't tell it otherwise. I have installed qmake, libqtcore4, libqt4-dev and several other packages. To add insult to injury, _I am using the Qt4 version of Cmake._ Am I simply missing the _real_ QtCore package or is the library somewhere incredibly non-obvious?

I'm currently having an annoying issue with the latest version of Skype 4.3.0.37 (installed from the RPM on a 64bit machine following the official documentation ). For some unknown to me reason, I'm unable to input any character other than English ones (i.e. cyrillic characters would appear something similar to "това е тесÑ"). When I start Skype from a console I get the following output: QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv_open failed QIconvCodec::convertToUnicode: using Latin-1 for conversion, iconv_open failed I can write in cyrillic on every other program but not in Skype. I've checked /usr/share/fonts and I have fonts installed there so I'm not quite sure what seems to be the problem here. Any ideas on what's missing? OS: OpenSUSE 13.1x64_84
Skype: 4.3.0.37

Using yum install qt has installed qt.i686 1:4.6.2-28.el6_5 to my /usr/share folder on Centos 6.5 but I need to follow these instructions to get chessx working: > To compile ChessX, you need Qt version 4.2.0 or above. 2. Compilation Compiling the source is simple. Execute: qmake and then make If the compilation is successful you should be able to run ChessX executable in bin subdirectory. It is called: chessx on Linux, chessx.app on Mac OS, chessx.exe on Windows 3. Problems If you have both Qt3 and Qt4 installed, verify that Qt4 is first on your path. You may check it, running: qmake -v But I don't know how to do the above exactly. chessx I have downloaded and installed in /usr/local/games as that seems logical to me.How do I set the path to make qmake work? Read "For simple projects, you only need to run qmake in the top level directory of your project." So the directory above chessx or qt4? NB: Since found out this is only to install locally where I was attempting to install remotely.

I had removed skype panel icon with this method : https://askubuntu.com/questions/7479/how-can-i-remove-the-skype-panel-icon-in-ubuntu-12-04-and-earlier/118979#118979 It worked fine, and I was using skype-wrapper to have skype in my messaging menu.. Then skype-wrapper has stopped working and I wanted to have my skype icon back.. I have reinstalled sni-qt (I never removed it but anyway I did reinstall it.) and I have reinstalled skype too (following this link :https://askubuntu.com/questions/68616/i-installed-sni-qt-and-there-is-no-indicator-for-skype-how-do-i-fix-this) but it didn't do anything.. (I will add that I don't need to whitelist it in dconf editor because I'm using elementaryOS Luna 2.0 and doesn't have a whitelist but a blacklist (which I have checked)) What package sould I add or update ? I tried to update QT libraries unsuccessfully.. Cheers! ElementaryOS 2.0 Luna, based on Ubuntu 12.04

Is it possible to change the order of font style? In qtconfig-qt4, the default style was no longer Regular. Is it possible to re-order it? Maybe with something in /etc/fonts/conf.d? Anyone know it?
