◆ fillDocument

void Scratchpad::fillDocument ( bool fullContent = true )

slot

Fill the entire scratchpad with current document projection content.

Parameters

fullContent when True, full document projection is loaded in scratchpad, otherwise only content matching scratchpad viewport is loaded

Definition at line 206 of file Scratchpad.cpp.

◆ fillForeground

void Scratchpad::fillForeground ( )

slot

Fill the entire scratchpad with current foreground color.

Definition at line 156 of file Scratchpad.cpp.

◆ setScale

bool Scratchpad::setScale ( qreal scale ) const

slot

allow to manually set scratchpad zoom level Note: call method is ignored if canvasZoomLink() is True,

Parameters

scale zoom level to apply (1.00 = 100%)

Returns: if scale has been applied return True, otherwise return False

Definition at line 83 of file Scratchpad.cpp.

◆ viewportBounds

QRect Scratchpad::viewportBounds ( ) const

slot

The viewport indicates which part of scratchpad content is visible.

It takes in account the current translation & scale

Example 1:

Scratchpad size: 500x500
Scratchpad content: 2000x2000
Scratchpad scale: 1.0
Scratchpad pan: 0, 0 Returned viewport is a QRect(0, 0, 500, 500) matching content really visible in scratchpad. If scale is 2.00, returned viewport will be QRect(0, 0, 250, 250) If scale is 0.50, returned viewport will be QRect(0, 0, 1000, 1000)

Example 2:

Scratchpad size: 500x500
Scratchpad content: 2000x2000
Scratchpad scale: 2.0
Scratchpad pan: 500, 1500 Returned viewport is a QRect(500, 1500, 250, 250) matching content really visible in scratchpad.

Returns: scratchpad viewport bounds as a QRect
