Synopsis
inputMask(string mask)
Parameters
| Parameters | Description |
|---|---|
| mask | Input validation mask |
Description
When an input mask is set, the "text" property returns a modified copy of the line edit content where all the blank characters have been removed.
When using an input mask, the format of the text field must be set to
string.
In addition, the "Command" script of the text field must be used, i.e. return must be pressed to evaluate the input mask. Only if the input text follows the rules of the input mask - e.g. all required characters have been entered - the command script is triggered.
Functions like min() and max() can only be used for the float and int formats, not for the string format and therefore not when using inputMask.
The input mask is an input template string. It can contain the following elements:
- Mask Characters
- Defines the Category of input characters that are considered valid in this position
- Meta Characters
- Various special meanings
- Separators
- All other characters are regarded as immutable separators
The following table shows the mask and meta characters that can be used in an input mask.
