wxPGChoices Class Reference

Detailed Description

Helper class for managing choices of wxPropertyGrid properties.

Each entry can have label, value, bitmap, text colour, and background colour.

wxPGChoices uses reference counting, similar to other wxWidgets classes. This means that assignment operator and copy constructor only copy the reference and not the actual data. Use Copy() member function to create a real copy.

注意:

If you do not specify value for entry, index is used.

Member Function Documentation

void wxPGChoices::Add	(	const wxChar **	labels,
		const ValArrItem *	values = NULL
	)

Adds to current.

If did not have own copies, creates them now. If was empty, identical to set except that creates copies.

void wxPGChoices::Add	(	const wxArrayString &	arr,
		const wxArrayInt &	arrint
	)

Version that works with wxArrayString and wxArrayInt.

wxPGChoiceEntry& wxPGChoices::Add	(	const wxString &	label,
		const wxBitmap &	bitmap,
		int	value = wxPG_INVALID_VALUE
	)

Adds a single item, with bitmap.

wxPGChoiceEntry& wxPGChoices::Add

(

const wxPGChoiceEntry &

entry

)

Adds a single item with full entry information.

wxPGChoiceEntry& wxPGChoices::Add	(	const wxString &	label,
		int	value = wxPG_INVALID_VALUE
	)

Adds single item.

wxPGChoiceEntry& wxPGChoices::AddAsSorted	(	const wxString &	label,
		int	value = wxPG_INVALID_VALUE
	)

Adds single item, sorted.

void wxPGChoices::AllocExclusive

(

)

Creates exclusive copy of current choices.

void wxPGChoices::Assign

(

const wxPGChoices &

a

)

Assigns choices data, using reference counting.

To create a real copy, use Copy() member function instead.
