Spell Checking
Spell checking in TX Spell .NET for WPF reaches the user in two ways: misspelled words are underlined while they type, and a dialog walks through them when they ask for a check. Behind both is one TXSpellChecker component, which also hands your code the incorrect words and their suggestions. Read on for what users see and how you control it, from connecting the first editor to building a correction interface of your own.
How Spell Checking Works
A TXSpellChecker, declared as a resource of the window, holds the dictionaries and does the checking. How it reaches the text depends on the control:
- TX Text Control checks the words itself once its
SpellCheckerproperty holds the key of the spell checker resource. It underlines misspelled words, offers suggestions in its context menu and opens a spelling dialog, all without code. - Any other control, such as a
TextBoxor aRichTextBox, passes its text to the spell checker'sCheckmethod. The result is a list of incorrect words that your code marks, or that the spell check dialog of TX Spell .NET walks through.
One spell checker serves every control in a window, and its dictionaries decide the languages. Dictionaries and Languages covers them.
