Defines a list of special delimiters. Moves the caret to the previous line. Sets the x width size increment to w and the y height size increment to h. When the window state changes, the widget receives a of type.

Determines the topmost visible line. Replaces the current selection with the specified text. Also note that semi-transparent windows update and resize significantly slower than opaque windows. The default Boolean value is set by the matplotlibrc file, and may be customized like any other configuration parameter see.

Qt Documentation Snapshots - The parent index corresponds to the parent into which the new rows are inserted; first and last are the row numbers that the new rows will have after they have been inserted. For example a button that only contains an icon needs to set this property to work with screen readers.

The static methods and conveniently perform this conversion achieving a precision of one millisecond on all Qt versions. If a different time spec time zone shall be class, see. This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day hierardhy />For example, if the axis range spans a few years class that there is one tick per year, ticks will be positioned on 1. This is intuitive diagram, due to leap years, will result in slightly diagram tick intervals hierarcgy unnoticeable. The same can be seen in the image above: even though the number of days varies month by month, this hiierarchy generates ticks on the same day of each month. July, 9:45 to this hierarchy, the yearly ticks will end up on 15. July at 9:45 of every year. The hierarchy can be created and assigned to an axis like this: Sets the tick origin see in seconds since Epoch 1. For example, If you pass 15. July, 9:45 to this method and the tick interval happens to be one tick per year, the ticks will end up on 15. July hiearchy 9:45 of every year. This is the format used as Qt5 coordinates by. Note that this tick step isn't diagarm exactly Qt5 generating the tick vector inbut only as a guiding value requiring some correction for each individual tick interval. Otherwise this would lead to unintuitive date displays, e. The same problem arises with leap years. For general information about this virtual method, see the base class implementation.

Steps Connect the points with a step function. This parameter only makes sense if window is a valid window. This version repaints a region rgn inside the widget. Warning: Calling move or inside can lead to infinite recursion. Also the build output is parsed gcc and msvc supported. First, a focus about to change event is sent to the focus widget if any to tell it that it is about to lose the focus. This is only relevant for input widgets. These are the number-line-like objects circled in green. Initializes the window sets the geometry etc. To return from full-screen mode, call.
