ObjectGetInteger
The function returns the value of the corresponding object property. The object property must be of the datetime, int, color, bool or char type. There are 2 variants of the function.
- Immediately returns the property value.
long ObjectGetInteger(
long chart_id, // chart identifier
string name, // object name
ENUM_OBJECT_PROPERTY_INTEGER prop_id, // property identifier
int prop_modifier=0 // property modifier, if required
);
- Returns true or false, depending on the success of the function. If successful, the property value is placed to a receiving variable passed by reference by the last parameter.
bool ObjectGetInteger(
long chart_id, // chart identifier
string name, // object name
ENUM_OBJECT_PROPERTY_INTEGER prop_id, // property identifier
int prop_modifier, // property modifier
long& long_var // here we accept the property value
);
Parameters
chart_id
[in] Chart identifier. 0 means the current chart.
name
[in] Name of the object.
prop_id
[in] ID of the object property. The value can be one of the values of the ENUM_OBJECT_PROPERTY_INTEGER enumeration.
prop_modifier
[in] Modifier of the specified property. For the first variant, the default modifier value is equal to 0. Most properties do not require a modifier. It denotes the number of the level in Fibonacci tools and in the graphical object Andrew's pitchfork. The numeration of levels starts from zero.
long_var
[out] Variable of the long type that receives the value of the requested property.
Return Value
The long value for the first calling variant.
For the second variant the function returns true, if this property is maintained and the value has been placed into the long_var variable, otherwise returns false. To read more about the error call GetLastError().
Note
The function uses a synchronous call, which means that the function waits for the execution of all commands that have been enqueued for this chart prior to its call, that is why this function can be time consuming. This feature should be taken into account when working with a large number of objects on a chart.
