    • getName

      public String getName()
      Returns the name of this component.

      Default: null.

      Don't use this method if your application is purely based on ZK's event-driven model.

      The name is used only to work with "legacy" Web application that handles user's request by servlets. It works only with HTTP/HTML-based browsers. It doesn't work with other kind of clients.

    • setName

      public void setName(String name)
      Sets the name of this component.

      Don't use this method if your application is purely based on ZK's event-driven model.

      The name is used only to work with "legacy" Web application that handles user's request by servlets. It works only with HTTP/HTML-based browsers. It doesn't work with other kind of clients.

      Parameters:
      name - the name of this component.
    • getErrorMessage

      public String getErrorMessage()
      Returns the error message that is caused when user entered invalid value, or null if no error at all.

      The error message is set when user has entered a wrong value, or setValue is called with a wrong value. It is cleared once a correct value is assigned.

      If the error message is set, we say this input is in the error mode. Any following invocation to getText() or getValue will throw any exception. Example, Textbox.getValue() and Intbox.getValue().

    • setErrorMessage

      public void setErrorMessage(String errmsg)
      Associates an error message to this input. It will cause the given error message to be shown at the client.

      Notice that the application rarely invokes this method. Rather, throw WrongValueException instead.

      Notice it does not invoke CustomConstraint.showCustomError(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.WrongValueException) even if getConstraint() implements CustomConstraint.

      Since:
      5.0.4
    • clearErrorMessage

      public void clearErrorMessage(boolean revalidateRequired)
      Clears the error message.

      The error message is cleared automatically, so you rarely need to call this method. However, if a constraint depends on multiple input fields and the error can be corrected by changing one of these fields, then you may have to clear the error message manually by invoking this method.

      For example, assume you have two Intbox and want the value of the first one to be smaller than that of the second one. Then, you have to call this method for the second intbox once the validation of the first intbox succeeds, and vice versa. Otherwise, the error message for the second intbox remains if the user fixed the error by lowering down the value of the first one Why? The second intbox got no idea to clear the error message (since its content doesn't change).

      Parameters:
      revalidateRequired - whether to re-validate the current value when getText() or others (such as Intbox.getValue()) is called. If false, the current value is assumed to be correct and the following invocation to getText() or others (such as Intbox.getValue()) won't check the value again. Note: when an input element is constructed, the initial value is assumed to be "not-validated-yet".
      Since:
      3.0.1
    • clearErrorMessage

      public void clearErrorMessage()
      Clears the error message. It is the same as clearErrorMessage(false). That is, the current value is assumed to be correct. getText() or others (such as Intbox.getValue()) won't re-validate it again.

      The error message is cleared automatically, so you rarely need to call this method.

      See Also:
    • getText

      public String getText() throws org.zkoss.zk.ui.WrongValueException
      Returns the value in the String format. In most case, you shall use the setValue method instead, e.g., Textbox.getValue() and Intbox.getValue().

      It invokes checkUserError() to ensure no user error.

      It invokes coerceToString(java.lang.Object) to convert the stored value into a string.

      Throws:
      org.zkoss.zk.ui.WrongValueException - if user entered a wrong value
    • setText

      public void setText(String value) throws org.zkoss.zk.ui.WrongValueException
      Sets the value in the String format. In most case, you shall use the setValue method instead, e.g., Textbox.setValue(java.lang.String) and Intbox.setValue(java.lang.Integer).

      It invokes coerceFromString(java.lang.String) first and then validate(java.lang.Object). Derives might override them for type conversion and special validation.

      Parameters:
      value - the value; If null, it is considered as empty.
      Throws:
      org.zkoss.zk.ui.WrongValueException
    • coerceFromString

      protected abstract Object coerceFromString(String value) throws org.zkoss.zk.ui.WrongValueException
      Coerces the value passed to setText(java.lang.String).

      Deriving note:
      If you want to store the value in other type, say BigDecimal, you have to override coerceToString(java.lang.Object) and coerceFromString(java.lang.String) to convert between a string and your targeting type.

      Moreover, when Textbox is called, it calls this method with value = null. Derives shall handle this case properly.

      Throws:
      org.zkoss.zk.ui.WrongValueException
    • coerceToString

      protected abstract String coerceToString(Object value)
      Coerces the value passed to setText(java.lang.String).

      Default: convert null to an empty string.

      Deriving note:
      If you want to store the value in other type, say BigDecimal, you have to override coerceToString(java.lang.Object) and coerceFromString(java.lang.String) to convert between a string and your targeting type.

    • validate

      protected void validate(Object value) throws org.zkoss.zk.ui.WrongValueException
      Validates the value returned by coerceFromString(java.lang.String).

      Default: use getConstraint()'s Constraint.validate(org.zkoss.zk.ui.Component, java.lang.Object), if not null.

      You rarely need to override this method.

      Throws:
      org.zkoss.zk.ui.WrongValueException
    • showCustomError

      protected org.zkoss.zk.ui.WrongValueException showCustomError(org.zkoss.zk.ui.WrongValueException ex)
      Shows the error message in the custom way by calling (CustomConstraint.showCustomError(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.WrongValueException), if the constraint implements CustomConstraint.

      Derived class shall call this method before throwing WrongValueException, such that the constraint, if any, has a chance to show the error message in a custom way.

      Parameters:
      ex - the exception, or null to clean up the error.
      Returns:
      the exception (ex)
    • getMaxlength

      public int getMaxlength()
      Returns the maxlength.

      Default: 0 (non-positive means unlimited).

      public void setMaxlength(int maxlength)
      Sets the maxlength.

      The length includes the format, if specified.

    • getCols

      public int getCols()
      Returns the cols.

      Default: 0 (non-positive means the same as browser's default).

      public String getConstraintString()
      Returns the raw constraint string value if any.
      Since:
      10.0.0
    • getTargetValue

      protected Object getTargetValue() throws org.zkoss.zk.ui.WrongValueException
      Returns the value in the targeting type. It is used by the deriving class to implement the getValue method. For example, Intbox.getValue() is the same as this method except with a different signature.

      It invokes checkUserError() to ensure no user error.

      Throws:
      org.zkoss.zk.ui.WrongValueException - if the user entered a wrong value
      See Also:
    • getRawValue

      public Object getRawValue()
      Returns the raw value directly with checking whether any error message not yet fixed. In other words, it does NOT invoke checkUserError().

      Note: if the user entered an incorrect value (i.e., caused WrongValueException), the incorrect value doesn't be stored so this method returned the last correct value.

      See Also:
    • getRawText

      public String getRawText()
      Returns the text directly without checking whether any error message not yet fixed. In other words, it does NOT invoke checkUserError().

      Note: if the user entered an incorrect value (i.e., caused WrongValueException), the incorrect value doesn't be stored so this method returned the last correct value.

      See Also:
    • setRawValue

      public void setRawValue(Object value)
      Sets the raw value directly. The caller must make sure the value is correct (or intend to be incorrect), because this method doesn't do any validation.

      If you feel confusing with setValue, such as Textbox.setValue(java.lang.String), it is usually better to use setValue instead. This method is reserved for developer that really want to set an 'illegal' value (such as an empty string to a textbox with no-empty constraint).

      Note: since 3.0.1, the value will be re-validate again if getText() or others (such as Intbox.getValue()) is called. In other words, it is assumed that the specified value is not validated yet -- the same state when this component is created. If you want to avoid the re-validation, you have to invoke clearErrorMessage().

      Like setValue, the result is returned back to the server by calling getText().

      See Also:
    • setValueDirectly

      protected void setValueDirectly(Object value)
      Sets the value directly. Note: Unlike setRawValue(java.lang.Object) (nor setValue), this method assigns the value directly without clearing error message or synchronizing with the client.

      It is usually used only the constructor. Though it is also OK to use setRawValue(java.lang.Object) in the constructor, this method has better performance.

      Since:
      3.0.3
    • isValid

      public boolean isValid()
      Returns the current content of this input is correct. If the content is not correct, next call to the getValue method will throws WrongValueException.
    • setSelectedText

      public void setSelectedText(int start, int end, String newtxt, boolean isHighLight)
      Sets the text of this InputElement to the specified text which is beginning with the new start point and ending with the new end point.
      Parameters:
      start - the start position of the text (included)
      end - the end position of the text (excluded)
      newtxt - the new text to be set.
      isHighLight - Sets whether it will represent highlight style or cursor style.If the start point same with the end point always represent cursor style.
    • setSelectionRange

      public void setSelectionRange(int start, int end)
      Sets the selection end to the specified position and the selection start to the specified position. The new end point is constrained to be at or after the current selection start. If the new start point is different with the new end point, then will represent the result of highlight in this text.

      Set both arguments to the same value to move the cursor to the corresponding position without selecting text.

      Parameters:
      start - the start position of the text (included)
      end - the end position of the text (excluded)
    • setInsertedText

      public void setInsertedText(String text)
      Inserts the text at the current cursor position. It would trigger focus and change event.
      Parameters:
      text - the text to be inserted
      Since:
      8.5.1
    • checkUserError

      protected void checkUserError() throws org.zkoss.zk.ui.WrongValueException
      Checks whether user entered a wrong value (and not correct it yet). Since user might enter a wrong value and moves on to other components, this method is called when getText() or getTargetValue() is called.

      Derives rarely need to access this method if they use only getText() and getTargetValue().

      Throws:
      org.zkoss.zk.ui.WrongValueException
    • getErrorboxSclass

      public String getErrorboxSclass()
      Returns the class name of the custom style applied to the errorbox of this component.
      Returns:
