nexxT.services.gui.GuiLogger module

This module provides the gui logging service for nexxT.

class nexxT.services.gui.GuiLogger.GuiLogger

Bases: ConsoleLogger

Logging service in GUI mode.

__init__(self, /, parent: PySide6.QtCore.QObject | None = None, *, objectName: str | None = None) → None

Initialize self. See help(type(self)) for accurate signature.

detach()

This slot is called when the service is removed from the framework

removeHandler()

Remove logging handler from python logging system.

setLogLevel()

Sets the current log level from the calling action.

Returns:

None

setNumEntries()

Sets the number of displayed log entries from the calling action.

staticMetaObject = PySide6.QtCore.QMetaObject("GuiLogger" inherits "ConsoleLogger": Methods:   #5 type=Slot, signature=detach() )

class nexxT.services.gui.GuiLogger.LogHandler(logView)

Bases: Handler

Python logging handler which passes python log records to the gui.

__init__(logView)

Initializes the instance - basically setting the formatter to None and the filter list to empty.

emit(record)

called when a new log record is created

Parameters:

record – a log record instance (see python docs)

Returns:

class nexxT.services.gui.GuiLogger.LogView

Bases: QTableView

Class implementing the GUI log display.

class LogModel

Bases: QAbstractItemModel

Model/view model for log entries. The entries are held in a python list.

__init__(self, /, parent: PySide6.QtCore.QObject | None = None) → None

Initialize self. See help(type(self)) for accurate signature.

clear()

removes all entries from the list

Returns:

None

columnCount(parent)

Overwritten from QAbstractItemModel

Parameters:

parent – a QModelIndex instance

Returns:

the number of columns (constant)

data(modelIndex, role)

Overwritten from QAbstractItemModel

Parameters:

• modelIndex – a QModelIndex instance

• role – the role

Returns:

the requested data

headerData(section, orientation, role)

Overwritten from QAbstractItemModel

Parameters:

• section – the section index

• orientation – the orientation

• role – the item role

Returns:

the section label

index(row, column, parent)

Overwritten from QAbstractItemModel

Parameters:

• row – integer

• column – integer

• parent – a QModelIndex instance

Returns:

a QModelIndex for the specified item

parent(index)

Overwritten from QAbstractItemModel

Parameters:

index

Returns:

invalid model index (because we have a 2D table)

rowCount(parent)

Overwritten from QAbstractItemModel

Parameters:

parent – a QModelIndex instance

Returns:

number of log entries

setSingleLineMode(enabled)

called from the table view to indicate single line mode (in this mode only the last line of a log message is displayed.

Parameters:

enabled – boolean

Returns:

staticMetaObject = PySide6.QtCore.QMetaObject("LogModel" inherits "QAbstractItemModel": )

update(queue)

add queued items to model

Parameters:

queue – a python Queue instance

Returns:

None

__init__(self, /, parent: PySide6.QtWidgets.QWidget | None = None, *, showGrid: bool | None = None, gridStyle: PySide6.QtCore.Qt.PenStyle | None = None, sortingEnabled: bool | None = None, wordWrap: bool | None = None, cornerButtonEnabled: bool | None = None) → None

Initialize self. See help(type(self)) for accurate signature.

addLogRecord(items)

Add a log record to the synchronized queue

Parameters:

items – a tuple of (timestamp[str], level[int], message[str], modulename[str], filename[str], lineno[int])

Returns:

None

changeEvent(event)

This for instance happens when the style sheet changed. It may affect the calculated row height. So invalidate:

Parameters:

event – the event causing the change

Returns:

clear()

Clears the view

Returns:

None

setFollow(follow)

set follow mode

Parameters:

follow – a boolean

Returns:

None

setUniformRowHeights(enabled)

Takeover from QTreeView, see also here https://stackoverflow.com/questions/50943356/qtableview-performance

Parameters:

enabled

Returns:

sizeHintForRow(row)

return a size hint for the given row index

Parameters:

row – the row index as integer

Returns:

the height of the row as integer

staticMetaObject = PySide6.QtCore.QMetaObject("LogView" inherits "QTableView": )

update()

Called periodically to synchronize model with added log records

Returns:

None
