IntProperty(label=PG_LABEL, name=PG_LABEL, value=0)

IntProperty(label, name, value)

__init__(self, *args, **kw)

Overloaded Implementations:

---

__init__ (self, label=PG_LABEL, name=PG_LABEL, value=0)

Parameters:

• label (string) –
• name (string) –
• value (long) –

DoGetValidator(self)

Returns pointer to the wx.Validator that should be used with the editor of this property (None for no validator).

Setting validator explicitly via SetPropertyValidator will override this.

In most situations, code like this should work well (macros are used to maintain one actual validator instance, so on the second call the function exits within the first macro):

class MyPropertyClass(wx.propgrid.IntProperty):
    ...
    def DoGetValidator(self):
        validator = MyValidator(...)

        ... prepare validator...

        return validator

Return type:Validator

Note

You can get common filename validator by returning wx.propgrid.FileProperty.GetClassValidator . wx.propgrid.DirProperty, for example, uses it.

---

static DoValidation(property, value, pValidationInfo, mode=PG_PROPERTY_VALIDATION_ERROR_MESSAGE)

Validation helper.

Parameters:

• property (wx.propgrid.PGProperty) –
• value (LongLong_t) –
• pValidationInfo (wx.propgrid.PGValidationInfo) –
• mode (int) –

Return type:

bool

---

static GetClassValidator()

Return type:Validator

IntToValue(self, variant, number, argFlags=0)

Converts integer (possibly a choice selection) into Variant value appropriate for this property.

Parameters:

• variant (PGVariant) – On function entry this is the old value (should not be NullVariant in normal cases). Translated value must be assigned back to it.
• number (int) – Integer to be translated into variant.
• argFlags (int) – If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable value instead of displayable one.

Return type:

bool

Returns:

Returns True if resulting Variant value was different.

Note

• If property is not supposed to use choice or spinctrl or other editor with int-based value, it is not necessary to implement this method.
• Default implementation simply assign given int to m_value.
• If property uses choice control, and displays a dialog on some choice items, then it is preferred to display that dialog in IntToValue instead of OnEvent.
• You might want to take into account that m_value is Mull variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).

---

StringToValue(self, variant, text, argFlags=0)

Converts text into Variant value appropriate for this property.

Parameters:

• variant (PGVariant) – On function entry this is the old value (should not be NullVariant in normal cases). Translated value must be assigned back to it.
• text (string) – Text to be translated into variant.
• argFlags (int) – If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable value instead of displayable one (they may be different). If wx.propgrid.PG_COMPOSITE_FRAGMENT is set, text is interpreted as a part of composite property string value (as generated by ValueToString called with this same flag).

Return type:

bool

You might want to take into account that m_value is Null variant if property value is unspecified (which is usually only case if you explicitly enabled that sort behaviour).

Returns:Returns True if resulting Variant value was different.

Note

Default implementation converts semicolon delimited tokens into child values. Only works for properties with children.

---

ValidateValue(self, value, validationInfo)

Implement this function in derived class to check the value.

Return True if it is ok. Returning False prevents property change events from occurring.

Parameters:

• value (PGVariant) –
• validationInfo (wx.propgrid.PGValidationInfo) –

Return type:

bool

Note

• Default implementation always returns True.

---

ValueToString(self, value, argFlags=0)

Converts property value into a text representation.

Parameters:

• value (PGVariant) – Value to be converted.
• argFlags (int) – If 0 (default value), then displayed string is returned. If wx.propgrid.PG_FULL_VALUE is set, returns complete, storable string value instead of displayable. If wx.propgrid.PG_EDITABLE_VALUE is set, returns string value that must be editable in textctrl. If wx.propgrid.PG_COMPOSITE_FRAGMENT is set, returns text that is appropriate to display as a part of string property’s composite text representation.

Return type:

string

Note

Default implementation calls GenerateComposedValue .
