While QtCore module contains non-GUI functionality for working with file and directory etc., QtGui module contains all the graphical controls. PyQt API is a set of modules containing a large number of classes and functions. The latest version of PyQt can be downloaded from its official website − PyQt was developed by RiverBank Computing Ltd. It is a Python interface for Qt, one of the most powerful, and popular cross-platform GUI library. ((decoration = NULL & noBorder()) || (decoration != NULL & !noBorder())))Īnd it is clear if noBorder() is true, then the window decoration->show() doesn't happen.PyQt is a GUI widgets toolkit. Void Client::updateDecoration(bool check_workspace_pos, bool force) Now, noBorder() member function is used in the following routine: It's not full-screen, but it makes sense that isFullScreen() appears above.
#Qdockwidget add minimize maximize buttons full
I take it the plugin is enabled (in this case Qxygen), as there are plenty of elements of the Octave graphical application that have full decorations: dialog boxes, the main app, etc. Return decorationPlugin()->isDisabled() || noborder || isFullScreen() The important parameter in the KDE Window Manager client appears to be the setting "noborder".
#Qdockwidget add minimize maximize buttons code
In any case, I've looked around in the source code without identifying exactly where the problem is, but I have a hunch that I think narrows things down slightly. In some sense, Oxygen is rolling its own implementation of Qt, using Qt, if you follow. Again, all fine, but I'm wondering if those who developed Oxygen may have not considered the above "rules", because it isn't obvious that one should check such things when they're in fact using the Qt framework.
So, it looks to me, where QDockWidget is used by Oxygen, it is more for the sake of settings and not calling member functions. Of course, Oxygen / Window Manager can't, say, call member functions associated with Qt QDockWidget and so on, without being very careful.
The decorations are written in Qt, the buttons, signals/slots, etc. Oxygen is unique in that it, along with the KDE Window Manager, is written in Qt. I was perplexed by how this could come about, but having looked at some KDE code from the git repository, I think I have a better understanding. Furthermore, the decorations rule Qt describes also works for non-KDE frameworks. To be more specific, I'm attaching a screenshot of the exact KDE setting that matters, Widget Style & Behavior. Also, I've tested the above Qt behavior in all the non-Oxygen KDE frameworks on Kubuntu 18.x and those show decorations nicely. One might argue that semantically Qt doesn't exactly say such a thing, but there is enough inference. I'll summarize: A QDockWidget in a docked state that is floated and assigned the above window attributes is not acquiring window decorations in Oxygen. For Oxygen theme, we've found that no decorations appear. Should display a full array of decorations, buttons, borders, drag-movement. SetWindowFlags (Qt::Window | Qt::CustomizeWindowHint | Qt::WindowTitleHint | Qt::WindowMinMaxButtonsHint | Qt::WindowCloseButtonHint) SetParent (0, Qt::Window | Qt::CustomizeWindowHint | Qt::WindowTitleHint | For background, details are hereīut I think that link discussion is too much to absorb, so I will try to summarize here. We,ve been struggling with a bug in the Octave application in which the reparenting of the Qt window, a QDockWidget, to 0 does not create a top level window with decorations. I'm running Kubuntu (18.x) right now, but the same behavior applies to Mint KDE and Mageia latest versions. Widget Style & Behavior setting for which Oxygen has no decorations
