I'm trying out a 43Inch screen and I'm using the gnome shell extension gTile, and I can't figure out how to:
have a preset to bring all windows to center with predfined dimensions, i.e. 70%x50%
have a hotkey to bring the current window to center with same predefined dimensions
have a hotkey to set all windows in right or left column, i.e. devide the screen in half.
Any ideas how to go about it?
The built in decsription doesn't tell me much:
Thanks in advance!
is not implemented, 2. is a standard gTile functionality with preconfigured hotkey Super-Alt-5. 3. There is autotile in multiple columns, you need to autotile in 2 columns. Super-Enter to activate gTile, then 2 (means press 2).

Some parts of widgets (e.g. button in a QDateEdit) are by far too small so they cannot be properly used with touch screens.
On my system, the sliders, e.g. for the widget's scroll areas, become bigger if I use setGlobalStrut() accordingly. But a slider has buttons with arrows which are very small on our system. The same is true for QDateWidget. The Buttons with the arrows are very, very small in our system and therefore cannot be well used with touchscreen.
We use Pvbrowser (pvbrowser.org) for visualisation of a gas measurement device on an embedded system with touchscreen. It is running an embedded linux yocto/poky "jethroo". By passing a parameter, the application calls QApplication::setGlobalStrut. The effect is, that some elements become bigger, but not sub elements within the widget.
Is there any way to change the appearance of Qt applications on systems like this:
X11 was used instead of egl because the vnc functionality is needed. A display manager is not used and the windows manager is "matchbox". Qt is version 5.5.1.
In the meantime I have found a solution. The screen size was not set in X11 and xrandr reported 0 dpi.
If I set the dpi, e.g. by calling "xrandr --dpi 146" from mconsole, the size of arrow elements etc. within dateTime widgets, scroll bars or other are adjusted accordingly when the application is restarted.
Not only the widgets and its elements are changed but also the font size since it is given in points which depends on dpi.
I have a custom widget which has a QLineEdit & 2 QPushButtons inside it.
I want to align them generically so that they look the same on all platforms(WIN, LINUX & osX).
I tried to align them using offsets by manually checking different offsets. It worked fine for windows&linux but on mac, the buttons are hidden by the QLineEdit.
I am wondering if there's a generic way in which i can have these buttons inside QLineEdit which works for all platforms & scaling values.

As the image shows, i want to have two buttons just like the one in visual studio. I tried QComboBox but it din't solve the purpose as it's label is not editable.
I solved this on windows by moving the two buttons by their sizes,
adjFirstBtnWidth = lineEditWidth - firstButtonWidth - secondButtonWidth
adjSecondBtnWidth = lineEditWidth - secondButtonWidth
Now, I moved the first button by adjFirstBtnWidth & second button by adjSecondBtnWidth on x axis.
It seems to work on windows & Linux but I've to wait to see if it's working on OSX or not.
Hope this is helpful to someone.
I'm using a PiTFT on my pi and running a JavaFX program. I got the output going to the PiTFT by running fbcp in the background.
I had to set disable_overscan=1 in /boot/config.txt to get it to show the whole image. That all works fine now.
My problem is that the touch screen calibration doesn't seem to effect JavaFX apps. The X and Y axis are swapped. Does anybody know how to calibrate the touch screen for JavaFX apps?
I don't know if this is a problem with the touchscreen driver for the PiTFT or a JavaFX configuration problem, so I'm going to post the same question to the adafruit forums and if I get an answer in one place, I'll copy it to the other.
I've struggled with the same problem today, and I managed to figure it out.
The PiTFT is by default a portrait display with a resolution of 240x320. The driver conf is originally made to rotate the display. The touchscreen setting for X are aware of that and have the rotate option set accordingly. And yes, this will not affect JavaFX since it doesn't run in X.
What I did:
in /boot/config.txt
disable_overscan=1
framebuffer_width=480
framebuffer_height=640
#set specific CVT mode
hdmi_cvt 480 640 60 1 0 0 0
#set CVT as default
hdmi_group=2
hdmi_mode=87
hdmi_force_hotplug=1
With this, the main display resolution is set to 480x640, and overscan is disabled.
Next, in /etc/modprobe.d/adafruit.conf, change the rotate option to be 0.
Save everything and reboot. Then fbcp & java Main, and it should be working OK.
Btw, be aware that I used the pre-built raspbian image from adafruit.
The basic idea is: I would like to draw over everything on the screen.
One way I can imagine this is creating a transparent full-screen window without window controls (minimise, maximise, etc.) or borders. Then drawing into that window which is transparent. The problem I can think of is that I will be unable to control windows which are behind our transparent window.
How could I do something similar to this, without the mentioned problem? I would also like it to work on multiple operating systems if possible.
Edit:
The user will not be drawing with the mouse or other means on the screen, but will be able to continue use his desktop like normal, without that my program interferes in any way (other than the drawing on the screen). My program will only display something on the screen, which the user will be unable to interact with (at least that's the plan).
Qt 5 implements it:
QWidget w;
w.setWindowFlags(Qt::WindowTransparentForInput);
Qt 4 didn't support this functionality yet - see QTBUG-13559. The bug report had a hint on what needed to be done for Windows.
The method you describe is the one to use; a transparent full-screen window.
If you're using the left mouse button to draw, you'll need a mechanism of switching modes to be able to select items through the window and send events to the operating system.
Is there any way to make console2 go fullscreen? I edit settings and increase window and buffer size but when I restart settings are reset to 63 rows in window size.
I've found that the maximise button is disabled, but you can get around it by setting Run option of the executable's shortcut to Maximised.
Better yet you can hide the window title bar in Console2's settings (Appearance > More... > Caption).
Here's the final result:
So, I've found this fork of Console2 which is amazingly better, it's called ConsoleZ:
https://github.com/cbucher/console/wiki/Downloads
Besides the maximization, it provides find in tabs, fullscreen mode and split tabs. Totally worth to check it out, IMHO.
EDIT
Forgot to mention, you can just download and replace the binaries, and all your configurations will be kept, as far as I've perceived.

OK I managed to do it on win7 but still no luck on XP. This is how I did it.
In Settings→Behavior, check the Initial position checkbox and left the X and Y as default 0
Restart console
After restart, resize window dragging the borders to fill whole screen
Restart again
In Settings→Appearance→More uncheck Caption and Border
I don't know why just entering rows and columns doesn't work. One has to resize the window and restart.
On my screen with this font it is 62 rows (with space left for tabs on bottom) and 238 columns. I have 24" monitor. I set font to be Consolas size 11.
You can change the number of rows to change tab settings.
Click "Edit"->"Setting"->"Tabs" and click "Add" button. Then, the new entry which name is "Console" appears in the tab name list. In the main tab menu on the bottom, input these two parameters in the fields.
Title: Cygwin
Shell: C:\cygwin\bin\bash.exe --login -i
At last, move up the "Cygwin" entry to the top and restart console2. Now you can change the number of rows.
The detail how to configure tab settings is here.

In order to make Console2 have the desired window size (even when opening a new tab which generally causes the entire app's window to resize to smaller), do the following:
View -> Console Window
In the console window that pops up, right-click its title bar and select Properties
Set the window width/height and buffer sizes as you like and click OK

I founded a small program called, sizer 3.34, that configure the window size of every program window you have.
When installed, it apears at the popup menu, when you click with the secundary mouse button at the top bar of a window. It allows you to config the three size profiles it has, and to add one, or more, if you want.
I think is a good solution for this issue (and for another programms that would have the same problem).
Reggards.
