Response to a custom widget signal

In Run MyScreens it is possible to respond to a particular signal (invokeSub()) of the custom

widget and call up a subprogram (SUB).

10 global variables, the so-called SIGARG, are available for passing values (custom widget

signal -> SUB), which are comparable to registers (REG) in configuration. This is where the

values transferred with the custom widget signal are stored.

The following transfer parameter data formats are supported:

● QByteArray

Calling the subroutine:

Description:

REG[9] = CallCWMethod("MyCWVar1", "myFunc1", 1+7, MyStringVar1, sin(MyRealVar) –

void invokeSub(const QString& rszSignalName, const

QVariantList& rvntList);

Custom widget signal with which a Run MyScreens subprogram is called.

rszSignalName

Name of the Run MyScreens subprogram to be called

QVariantList array for transferring parameters that are

stored in the global parameter SIGARG and which are

available in the configuration.

Maximum size: 10 elements

Data formats supported: see above

Note: The transfer parameters are always passed "By‐

Val," i.e. only the value and not, for example, the refer‐

ence to a variable is passed.
