### 22.2.8 Setting Title and Tip Text
|
||||
### Setting Title and Tip Text
|
||||
|
||||
When SLEDIT has ES_TIP styles, you can set tip text of the edit box using EM_SETTIPTEXT message, and get tip text of edit box using EM_GETTIPTEXT message.
|
||||
When `SLEDIT` has `ES_TIP` styles, you can set tip text of the edit box using
|
||||
`EM_SETTIPTEXT` message, and get tip text of edit box using `EM_GETTIPTEXT`
|
||||
message.

||||
|
||||
```cpp
|
||||
int len;
|
||||
char *tip_text;

`SendMessage` (hwndEdit, `EM_SETTIPTEXT`, len, (LPARAM)tip_text);
|
||||
SendMessage (hwndEdit, EM_SETTIPTEXT, len, (LPARAM)tip_text);
|
||||
```
|
||||
|
||||
Here lParam parameter specifies tip text string, wParam parameter specifies the length of the string; if tip_text is ended with ’\0’, wParam can be set to -1, if wParam is 0, tip_text can be NULL. EM_GETTIPTEXT message will return the current tip text string:
|

char tip_text[len+1];
|
||||
SendMessage (hwndEdit, EM_GETTIPTEXT, len, (LPARAM)tip_text);

||||
```
|
||||
|
||||
Here lParam parameter specifies title text string, wParam parameter specifies the length of the string; if tip_text is ended with ’\0’, wParam can be set as -1, if wParam is 0, tip_text can be NULL. EM_GETTIPTEXT message will return current title text string.

message will return current title text string.
|
||||
|
||||
```cpp
|
||||
int len;
|
||||
char `title_text[len+1];`
|
||||
`SendMessage` (hwndEdit, `EM_GETTITLETEXT`, len, (LPARAM)title_text);
|
||||
char title_text[len+1];
|
||||
SendMessage (hwndEdit, EM_GETTITLETEXT, len, (LPARAM)title_text);
|
||||
```
|
||||
|

## Notification Codes of Edit Box
|
||||
|

The edit box has not ES_NOTIFY style, so any edit box can generate notification messages, as listed below:
|
||||
- EN_SETFOCUS: The edit box has received the input focus.
|
||||
- EN_KILLFOCUS: The edit box has lost the input focus.
|
||||
- EN_CHANGE: The content in the edit box has been altered.
|
||||
- EN_UPDATE: The content in the edit box has been altered after edit box received MSG_SETTEXT, EM_RESETCONTENT, or EM_SETLINEHEIGHT message.
|
||||
- EN_ENTER: The user has pressed the ENTER key in the edit box.
|
||||
- EN_MAXTEXT: The inserting text exceeds the maximum limitation of the edit box.
|
||||
- EN_DBLCLK: The edit control is double clicked with the left button of the mouse.
|
||||
- EN_CLICKED: The edit control is clicked with the left button of the mouse.
|
