Inherits:

|
|
|
Imports:
|
|
QtQuick 1.1
|
|
|
|
Description:
|
|
Creates a simple plasma theme based text field.
|
|
Like kates..
|
|
|
|
Properties:
|
|
alias font:
|
|
Sets the font for the text area.
|
|
|
|
int inputMethodHints:
|
|
|
|
bool errorHighlight:
|
|
If it is true then the problematic lines will be highlighted.
|
|
|
|
alias cursorPosition:
|
|
Returns the cursor's position.
|
|
|
|
alias readOnly:
|
|
If this property is set to true the text cannot be edited by user interaction.
|
|
|
|
alias selectedText:
|
|
This read-only property provides the text currently selected in the text edit.
|
|
|
|
alias selectionEnd:
|
|
The cursor position after the last character in the current selection.
|
|
This property is read-only.
|
|
|
|
alias selectionStart:
|
|
The cursor position before the first character in the current selection.
|
|
This property is read-only.
|
|
|
|
alias text:
|
|
The text to display
|
|
|
|
string placeholderText:TODO
|
|
|
|
alias echoMode:
|
|
Specifies how the text should be displayed in the TextInput.
|
|
|
|
TextInput.Normal - Displays the text as it is. (Default)
|
|
TextInput.Password - Displays asterixes instead of characters.
|
|
TextInput.NoEcho - Displays nothing.
|
|
TextInput.PasswordEchoOnEdit - Displays all but the current character as asterixes.
|
|
|
|
alias validator:
|
|
Allows you to set a validator on the TextInput. When a validator is set the TextInput
|
|
will only accept input which leaves the text property in an acceptable or intermediate state.
|
|
The accepted signal will only be sent if the text is in an acceptable state when enter is pressed.
|
|
Currently supported validators are IntValidator, DoubleValidator and RegExpValidator.
|
|
An example of using validators is shown below, which allows input of integers
|
|
between 11 and 31 into the text input:
|
|
<code>
|
|
import QtQuick 1.0
|
|
TextInput{
|
|
validator: IntValidator{bottom: 11; top: 31;}
|
|
focus: true
|
|
}
|
|
</code>
|
|
|
|
alias maximumLength:
|
|
Sets the maximum length that the string can have.
|
|
|
|
alias acceptableInput:
|
|
This property is always true unless a validator has been set. If a validator has been set,
|
|
this property will only be true if the current text is acceptable to the validator as a final string
|
|
(not as an intermediate string)
|
|
|
|
alias activeFocus:
|
|
This property indicates whether the item has active focus.
|
|
An item with active focus will receive keyboard input.
