MQL5
- Added new 'void *' pointers to enable users to create abstract
collections of objects. A pointer to an object of any class can be saved
to this type of variable.
It is recommended to use the operator dynamic_cast<class name *>(void * pointer) in order to cast back. If conversion is not possible, the result is NULL.class CFoo { }; class CBar { }; //+------------------------------------------------------------------+ //| Script program start function | //+------------------------------------------------------------------+ void OnStart() { void *vptr[2]; vptr[0]=new CFoo(); vptr[1]=new CBar(); //--- for(int i=0;i<ArraySize(vptr);i++) { if(dynamic_cast<CFoo *>(vptr[i])!=NULL) Print("CFoo * object at index ",i); if(dynamic_cast<CBar *>(vptr[i])!=NULL) Print("CBar * object at index ",i); } CFoo *fptr=vptr[1]; // Will return an error while casting pointers, vptr[1] is not an object of CFoo } //+------------------------------------------------------------------+
- Added support for the operator [ ] for strings. The operator enables
users to get a symbol from a string by index. If the specified index is
outside the string, the result is 0.
string text="Hello"; ushort symb=text[0]; // Will return the code of symbol 'H'
- Added a second version of the TesterInit event
handler with the int OnTesterInit(void) signature, which can return
INIT_SUCCEEDED (0) or INIT_FAILED (or any non-zero value). If
OnTesterInit returns a non-zero value, the optimization will not begin.
- Fixed an error, which could lead to different results returned by different ChartGetString overloaded functions.
Tester
- Added new commands and hot keys for visual testing. Now it is possible
to configure charts in the visual tester like in the terminal: to change
colors, to control visibility of various elements, to apply templates,
etc.
- Fixed operation of the Sleep function in the "Open prices" testing mode.
- Fixed formation of incorrect state of bars on timeframes W1 and MN1.
MetaEditor
- Added UI translation into Traditional Chinese.
