Colour Manager

The Colour Manager

• The colour manager is defined by colorm.cpp
• It's called by scribus.cpp as follows:

ColorManager* dia = new ColorManager(this, edc, doc, prefsManager->colorSetName(), prefsManager->appPrefs.CustomColorSets);

• The constructors parameters are named as:
  • QWidget* parent = this (cannot be used outside of the constructor)
  • ColorList EditColors = doco = edc = (HaveDoc ? doc->PageColors : prefsManager->colorSet())
  • ScribusDoc* m_Doc = doc
  • QString* docColSet = prefsManager->colorSetName() (cannot be used outside of the constructor)
  • QStringList customColSet = custColSet = prefsManager->appPrefs.CustomColorSets
• The list of colours are read by the colour manager from the palettes and written to a m_Doc property.
• The list of used colors can be read throug void m_Doc->getUsedColor(& ColorList &colorsToUse, bool spot)

Hide unused colours

Adding a preference field

• Add a property in prefsmanager.h
• Add a method for reading and one for writing it in prefsmanager.cpp

Setting the preference from the Colour Management Dialog

• Get the prefsManager like:

<strike>PrefsContext* dirs = PrefsManager::instance()->prefsFile->getContext("dirs");</strike>

• Add a checkbox to the dialog
• Read and set the preference
• "Notify" the strings that are to be translated
• Correctly filter the list according to the preference

Filter out the hidden colours in every colour list

• Find all the colour lists
• Check if the unused are to be shown, and if not, don't show them (probably, through asking m_Doc->getUsedColor()
• When the preference is changed, all the "created" lists are to be updated (cf. changing the language from preferences)

Non alphabetical order of the colours

Some general ideas:

• Put b/w on top
• Put grayscales at the end

An implementation proposal by kirun0:

• First, all greyscale colours were moved to the end of the list.
• Then, I converted all colours to HSL colourspace.
• The colours were grouped by hue, into chunks of about 30 degrees.
• They were then sorted by sat+lum, so the darker colours came first, followed by the bold colours, and the light *and washed out ones last (within the group)

This was, of course for a single fixed set, the parameters will probablary need tweaking for any other given set

Filter by color type

• All
• Used
• RGB
• CMYK
• Spot
• Grayscales

Accessibility

Faramond asked to extend the drop-down boxes in order to allow jumps to a desired named color by typing the first few letters of its name (like in a file manager.) The drop-downs could also be modified such that typing in a number jumps to color with the same number.
