metric()¶

minScale(self) → float¶: Returns the minimum scale, or 0 if no minimum scale set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. Any scale lower than the minimum scale will automatically be converted to the minimum scale. Except for 0 which is always allowed.

resizeEvent()¶

scale(self) → float¶: Returns the selected scale as a double. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

setScale()

scaleChanged¶: Emitted when user has finished editing/selecting a new scale. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. [signal]

scaleString(self) → str¶: Returns the selected scale as a string, e.g. “1:150”.

setScaleString()

sender()¶

senderSignalIndex()¶

setMinScale(self, scale: float)¶: Set the minimum allowed scale. Set to 0 to disable the minimum scale. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. Any scale lower than the minimum scale will automatically be converted to the minimum scale. Except for 0 which is always allowed.

setScale(self, scale: float)¶: Set the selected scale from a double. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

scale()

setScaleString(self, string: str) → bool¶: Set the selected scale from a string, e.g. “1:150”.

sharedPainter()¶

showEvent()¶

showPopup(self)¶

tabletEvent()¶

timerEvent()¶

toDouble(string: str) → Tuple[float, bool]¶: Helper function to convert a scale string to double. The returned value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map. If specified, ok will be set to true if the string was successfully interpreted as a scale.

See also

toString()

toString(scale: float) → str¶

Helper function to convert a scale double to scale string. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

The returned string will be rounded (e.g. 1:1000, not 1:1000.345).
