Selects the word containing the insertion point in a RichTextEdit control.
RichTextEdit and DataWindow controls
rtename.SelectTextWord ( )
Argument |
Description |
|---|---|
rtename |
The name of the RichTextEdit or DataWindow control in which you want to select a word. The DataWindow object in the DataWindow control must be a RichTextEdit DataWindow. |
Integer. Returns the number of characters selected if it succeeds and -1 if a word cannot be selected or an error occurs.
A word is any group of alphanumeric characters. A word can include underscores and single quotes but does not include punctuation and special characters such as $ or #. If punctuation or special characters follow the selected word, they are not selected.
If the character after the insertion point is a space, punctuation, special character, or end-of-line mark, SelectTextWord does not select anything and returns -1.
The following statement selects the word containing the insertion point:
rte_1.SelectTextWord()
This example selects the word at the insertion point. If there is no word, it increments the position until it finds a word. It checks when it reaches the end of a line and wraps to the next line as it looks for a word. If this script is assigned to a command button and the button is clicked repeatedly, you step through the text word by word:
integer li_rtn
long llstart, lcstart, ll_lines, ll_chars
ll_lines = rte_1.LineCount()
ll_chars = rte_1.LineLength()
li_rtn = rte_1.SelectTextWord()
// -1 if a word is not found at the insertion point
DO WHILE li_rtn = -1
// Get the position of the cursor
rte_1.Position(llstart, lcstart)
// Increment by 1 to look for next word
lcstart += 1
// If at end of line move to next line
IF lcstart >= ll_chars THEN
lcstart = 1 // First character
llstart += 1 // next line
// If beyond last line, return
IF llstart > ll_lines THEN
RETURN 0
END IF
END IF
// Set insertion point
rte_1.SelectText(llstart, lcstart, 0, 0)
// In case it's a new line, get new line length
// Can't do this until the ins pt is in the line
ll_chars = rte_1.LineLength( )
// Select word, if any
li_rtn = rte_1.SelectTextWord()
LOOP
// Add code here to process the word (for example,
// passing the word to a spelling checker)
