I want to detect a Qt5 QWidgets application from its
window title using xdotool to test the GUI under GNU/Windows with the latest Xubuntu LTS distro.
When I create any minimal Qt application, with wmctrl -l I can detect it,
with xdotool it cannot be found, as shown here:
(note that searching for Enter s also fails)
Does anybody have a good experience with using xdotool on Qt QWidget applications,
without using tricks like grepping through the wmctrl scripts?
AFAIKS, I am not the only
one that has problems with this combination.
Sadly, I do not know which update caused this, but one day after the question, suddenly everything works as expected:
xdotool can detect Qt windows with spaces in its name as expected.

I would like to use heob to check my app for memory leaks. This is what i tried: I opened the project "analogclock" from the examples collection in qtcreator. After that i have chosen "Analyze" and "Heob" from the drop down menu. After choosing the heob path and a click on the ok button, the application starts and a console window "heob32" is displayed. But now nothing happens. Just the word "kill" is displayed in the console window. I can´t see any output and if i close the analogclock app i get the message: "heob: cannot create target process". Can anyone help me further to get useful output from heob?
What OS are you using and what heob did you install?
You need to download and install heob separately from Creator. Creator just installs a link without heob itself. Have you done this? Are you really running on a 32-bit system (there is a heob64 in case you are using a modern OS).
Did you configure your heob installation in Qt Creator correctly?
Can you run heob from the commandline with reasonable behaviour?
Greetings for the first time:
Usually I can work my way through problems like this but I think I need help for this one.
I have developed a small utility for myself to plot some data using Qt and Qwt under Mint. When I run the application from Qt Creator everything works fine. Once I added (export LD_LIBRARY_PATH="/usr/local/qwt-6.1.3/lib") to my .bashrc file, I can invoke the application from the terminal with “./PlotAccountsChange” and it woks. Also the ldd command shows all dependencies have been found.
The problem I am having is that the application can not be invoked from the Nemo file manager, or from the menu system if I add the link to the executable in the menu, or from a link to the executable placed on the desktop. In all of these cases I get no indication at all, just nothing happens. Any other application that I have created using Qt but that doesn’t use Qwt invokes without problems.
Thank you, regards,

I wrote a PySide application that should run on python2.7, on window,Linux and Docker container. The application contains Qtooltip and specific eventFilter that catches HoverEnter\HoverLeave.
The application works well on windows 10 and ubuntu 14.04 desktop but when trying to run it inside Ubuntu 14.04 container both features didn't work well:
The tooltip - It would seem that the text is covered by other tooltip text or totally black.
The eventFilter - The application can't get the hover event (didn't appear).
The main difference that I saw was that when running on Ubuntu desktop, some GTk libraries are loaded to the python process (according to the maps files).
I tried reproduce the problem by installing everything on Ubuntu server (without Gtk), and got the same effect as inside the container.
Even after installing Gtk on the server, still no change.
I think that I might have missed some dependencies, but can't find any documentation on the issue.
Thanks in advance,
Ok, after several days of trying figure that this is what was needed:
For the tooltip problem:
Adding WA_AlwaysShowToolTips
Change the stylesheet show that the transparent feature will work only for the QPushButton background and not the entire widget.
For the event problem:
Add the attribute: WA_Hover
Everything worked as should be after that
I am having problems with a Qt GUI application I created. Basically I created the application in my ubuntu to check if it compiles and works properly, however, if I set up the cross compiler (followed a tutorial and tried a hello world which works properly) and execute my code in the pi the UI does not display properly and basically I cant do anything:
· Text disappears from buttons
· Mouse disappears from screen (therefore cant click buttons)
· Cant navigate buttons using tab key
Any clues? maybe I cant use .ui files in the pi and have to use qml? Thank you in advance.
2 Screenshots of what I get with the pi and what the program should actually look like (ignore the second LCD display):

I’ve been told that Qt5 has different rendering platforms, the standard for my compiled version is “eglfs”, which is fullscreen EGL accelerated mobile application style. I need to run it another platform for example xcb or x11 with the command “./myprogram -platform xcb”. Unfortunatelly i only have the following platform options and none of them work: eglfs,linuxfb,minimal,minimalegl,offscreen. I dont now how to install these, i’ll google it see if i can find anything.

I'm new to Qt (using Qt SDK with Qt Creator) and in the process of creating a GUI. What I'm looking for is a FilteredTree like the one found in the Preferences of Eclipse. Is there something "ready to use" out there? I've tried all search queries I can think of but no results so far.
In case it matters I'm absolutely willing to update to the newest Qt version.
