postponeSettingsChanges()

void KisPaintOpPresetUpdateProxy::postponeSettingsChanges

signal

sigSettingsChangedUncompressedEarlyWarning

void KisPaintOpPresetUpdateProxy::sigSettingsChangedUncompressedEarlyWarning ( )

signal

Uncompressed signals are delivered in two stages. Firstly, the early warning version is emitted, then the normal. The early warning version is needed to let critical code, like KisPresetShadowUpdater, to perform necessary actions before other receivers got the notification. Don't use it unless you know what you are doing. Use normal sigSettingsChangedUncompressed() instead.

unpostponeSettingsChanges()

void KisPaintOpPresetUpdateProxy::unpostponeSettingsChanges

(

)

Unblocks sigSettingsChanged() and emits one signal if there were at least one dropped signal while the block was held.
