## Brief Introduction to Edit Box Control
Edit box control is one of the essential controls in GUI system, which is
mainly used to receive character input of the users and realize the function of
user interaction and text edition. In Realization, it is divided into single
line edit and multi-line edit. Single line edit box is used to receive single
line text input with comparatively simple user content, in comparison,
multi-line text is used to receive complicated and large volume of text input.
- Class hierarchical relation of edit box
- [`mWidget`](MiniGUIProgGuidePart2Chapter04.md#mwidget)
* [`mScrollWidget`](MiniGUIProgGuidePart2Chapter08.md#mscrollwidget)
* [`mItemView`](MiniGUIProgGuidePart2Chapter15.md)
* [`mScrollView`](MiniGUIProgGuidePart2Chapter15.md)
* [`mEdit`](MiniGUIProgGuidePart2Chapter13.md#medit)
* [`mSlEdit`](MiniGUIProgGuidePart2Chapter13.md#msledit)
* [`mMlEdit`](MiniGUIProgGuidePart2Chapter13.md#mmledit)

## `mEdit`
- *Control window class*: `NCSCTRL_EDIT`
- *Control English name*: Edit
- *Brief introduction*: Foundation class of edit box series controls, it is the
abstract parent class of single line edit box and multi-line edit box, which
defines the common use interface of the two.
- *Schematic diagram*: _Abstract class, and cannot be used directly_.
### Style of `mEdit`
It is inherited from the style of [`mScrollView`](MiniGUIProgGuidePart2Chapter15.md)
| *Style name* | *miniStudio property name* | *Explanation* |
|--------------|----------------------------|---------------|
| `NCSS_EDIT_LEFT` | `Align->Left` | Left aligned |
| `NCSS_EDIT_CENTER` | `Align->Center` | Horizontal centering |
| `NCSS_EDIT_RIGHT` | `Align->Right` | Right aligned |
| `NCSS_EDIT_UPPERCASE` | `Case->Upper` | The input content is automatically converted to capital letter |
| `NCSS_EDIT_LOWERCASE` | `Case->Lower` | The input content is automatically converted to lower case letter |

| `NCSS_EDIT_READONLY` | `ReadOnly->TRUE` | The content is read only |
| `NCSS_EDIT_BASELINE` | `BaseLine->TRUE` | Content underlined display |
### Property of `mEdit`
It is inherited from the property of [`mScrollView`](MiniGUIProgGuidePart2Chapter15.md).
| *Property* | *miniStudio property name* | *Type* | *Authority* | *Explanation* |
|------------|----------------------------|--------|-------------|----------------|
| `NCSP_EDIT_LIMITTEXT` | `MaxLength` | int | `RW` | Character number limit value |
| `NCSP_EDIT_CARETPOS` | -- | int | `RW` | Cursor location |
### Event of `mEdit`
It is inherited from the event of [`mScrollView`](MiniGUIProgGuidePart2Chapter15.md).
| *Event ID* | *Parameter* | *Explanation* |
|------------|-------------|---------------|
| `NCSN_EDIT_CHANGE` | -- | Content changes |
| `NCSN_EDIT_CONTCHANGED` | -- | When edit loses the focus, the content changes |
| `NCSN_EDIT_UPDATE` | -- | The content is refreshed when changed through `setText` and `resetContent` method or the property is changed |
| `NCSN_EDIT_SELCHANGED` | -- | The selected part changes |
| `NCSN_EDIT_MAXTEXT` | -- | Character number is saturated |
| `NCSN_EDIT_SETFOCUS` | -- | Get the focus |
| `NCSN_EDIT_KILLFOCUS` | -- | Lose the focus |
### Method of `mEdit`
It is inherited from the method of[`mScrollView`](MiniGUIProgGuidePart2Chapter15.md).
#### `setContent`
```cpp
void setContent(mEdit *self, const char* str, int start, int len)
```
- Parameter
- str -- literal content displayed in edi
- start -- display starting location (relative to the starting location of
str), 0 represents starting from the beginning
- len -- display character number, -1 represents ending till the end of str
- Explanation:
Set the display content of the edit box. The method will get altogether
characters from No. character location from str character string, and replace
the existing content in edit.
- Example:
```cpp
// In edit, character string starting from the sixth character till the end of characterstring “dddd Show Me” will be displayed, and here it is “Show Me”
_c(edit)->setContent(edit, "dddd Show Me", 6, -1);
```
#### `replaceText`
```cpp
void replaceText(mEdit *self, const char* str,
int start, int len, int replace_start, int replace_end)
```
- Parameter
- str -- source character string used for replacement
- start -- deviation of the source text used for replacement relative to str, 0
represents starting from the beginning
- len -- length used to the source text, -1 represents starting from start and
ending till str
- `replace_start` -- replace the starting location (relative to the existing
content in edit)
- `replace_end` -- replace the ending location (relative to the existing
content in edit)
- Explanation:
Replacement of character string, the method will get altogether characters
starting from No. character location from str character string, and replaces
the existing content from to in edit. Str is the character string to be
replaced to, start is the starting location relative to str, 0 represents
starting from the beginning, len is the length, -1 represents ending till the
end of str, `replace_start` and `replace_end` are the starting point and ending
point of the location to be replaced, and they are location deviation relative
to the existing text content in edit.
- Example:
```cpp
// In edit, character string starting from the sixth character to the end of the character string “dddd Show Me” will be used (here it is “Show Me”),
// To replace the characters from the second one to the tenth one of the existing text in edit
_c(edit)->replaceText(edit, "dddd Show Me", 6, -1, 2, 10);
```
#### insert
```cpp
void insert(mEdit *self, const char* str, int start, int len, int at)
```
- Parameter
- str -- source character string to be inserted
- start -- starting location of the source text used, 0 represents starting
from the beginning
- len -- length of the source text used, -1 represents starting from start, and
ending till str
- at -- location of the insert point (relative to the existing content in
edit), -1 represents the end
- Explanation:
Insert of the character string, the method will get altogether characters
starting from No. character location in str character string, and it is
inserting into location of No. character of the existing content in edit. Str
is the character string to be inserted, start is the starting location relative
to str, 0 represents starting from the beginning, len is the length, -1
represents ending till the end of str, at parameter is the location to insert,
and it is the location deviation relative to the existing text content in edit
- Example:
```cpp
//In edit, character string starting from the sixth character till the end of the character string “dddd Show Me” will be used (here it is “Show Me”),
// To insert to after the second character of the existing text in edit
_c(edit)->insert(edit, "dddd Show Me", 6, -1, 2);
```
#### append
```cpp
void append(mEdit *self, const char* str, int start, int len)
```
- Parameter
- str -- source character string to append
- start -- starting location of the source text used, 0 represents starting
from the beginning
- len -- length of the source text used, -1 represents starting from start and
ending till str
- Explanation:
Append the character string, the method will get altogether characters starting
from No. character location from str character string, and append to after the
existing content in edit. str is the character string to append, start is the
starting location relative to str, 0 represents starting from the beginning,
len is the length, and -1 represents ending till the end of str.
- Example:
```cpp
// In edit, character string starting from the sixth character till the end of the character string “dddd Show Me” will be used (here it is “Show Me”),
// To append till the end of the existing text in edit
_c(edit)->append(edit, "dddd Show Me", 6, -1);
```
#### `getTextLength`
```cpp
int getTextLength(mEdit *self)
```
- Explanation: Get length of the content of the character string in Edit
- Example:
```cpp
int text_len = _c(edit)->getTextLength(edit);
```
#### `getContent`
```cpp
int getContent(mEdit *self, char *strbuff, int buf_len, int start, int end)
```
- Parameter:
- strbuff -- get storage location to the character string (storage space shall
be distributed in advance)
- `buff_len` -- size of strbuff
- start -- starting location of the obtained content
- end -- ending location of the obtained content
- Explanation:
Get character string content in edit, and get the content from to location from
the existing content and write into strbuff, and the maximum number to write in
is limited to `buff_len.`
- Example:
```cpp
char buff[128];
_c(edit)->getContent(edit, buff, 127, 0, -1); // Get out all the content in edit, and buff stores 127 characters to the maximum
```
#### `setSel` and `getSel`
```cpp
int setSel(mEdit *self, int start, int end)
int getSel(mEdit *self, int *pstart, int *pend)
```
- Parameter:
- start \end -- starting point and ending point of the selected region
- pstart\pend -- starting point and ending point of the selected region, used
for function return
- Explanation:
Set and get the region of the selected text, and the last two parameters
correspond to the starting point and ending point of the selected region
respectively
- Example:
```cpp
_c(edit)->setSel(edit, 2, 10); // Set No.2 to No.10 characters of edit as selected status
int ps,pe;
_c(edit)->getSel(edit, &ps, &pe); // Get the selected region
```
#### `setMargin`
```cpp
void setMargin(mEdit *self, int left, int top, int right, int bottom)
```
- Parameter:
- left,top,right,bottom -- margin of left, top, right and bottom, the parameter
is not a concept of rectangle, and it just continues to use the data structure
of rectangle for the convenience of parameter transmission
- Explanation: Set left, top, right and bottom margin of the edit region
- Example:
```cpp
// Set margin
_c(edit)- >setMargin(edit, 10,10,10,10);
```
#### copy, paste, and cut
```cpp
void copy(mEdit *self)
void cut(mEdit *self)
void paste(mEdit *self)
TextCopyPaste * setCopyPaste(mEdit *self, TextCopyPaste* cp)
```
Cut, copy and paste aim at the operation of the selected region. In edit, a
group of operation set using minigui cut board is realized by default, and the
users can set operation set realized by itself through `setCopyPaste`.
#### makevisible
```cpp
BOOL makevisible(mEdit *self, int pos)
```
- Parameter:
- pos -- location needs to be visible
- Explanation:
Control scrolling of the edit region, making the characters of the location
`pos` become visible.
- Example:
```cpp
// Visible at No. 201 character
_c(edit)- >makevisible(edit, 201);
```
