		Window_t	wid
	)

Emits a signal when an event has been processed.

Used in TRecorder.

Definition at line 951 of file TGClient.cxx.

◆ ProcessEventsFor()

Bool_t TGClient::ProcessEventsFor ( TGWindow * w )

Like gSystem->ProcessEvents() but then only allow events for w to be processed.

For example to interrupt the processing and destroy the window, call gROOT->SetInterrupt() before destroying the window.

◆ ProcessLine()

void TGClient::ProcessLine	(	TString	cmd,
		Long_t	msg,
		Long_t	parm1,
		Long_t	parm2
	)

Execute string "cmd" via the interpreter.

Before executing replace in the command string the token $MSG, $PARM1 and $PARM2 by msg, parm1 and parm2, respectively. The function in cmd string must accept these as longs.

◆ ProcessOneEvent()

Bool_t TGClient::ProcessOneEvent ( )

protected

Process one event.

This method should only be called when there is a GUI event ready to be processed. If event has been processed kTRUE is returned. If processing of a specific event type for a specific window was requested kFALSE is returned when specific event has been processed, kTRUE otherwise. If no more pending events return kFALSE.

◆ RemoveUnknownWindowHandler()

void TGClient::RemoveUnknownWindowHandler ( TGUnknownWindowHandler * h )

Remove handler for unknown (i.e. unregistered) windows.

Definition at line 564 of file TGClient.cxx.

◆ ResetWaitFor()

void TGClient::ResetWaitFor ( TGWindow * w )

reset waiting

Definition at line 762 of file TGClient.cxx.

◆ SetEditDisabled()

void TGClient::SetEditDisabled ( Bool_t on = kTRUE )

If on is kTRUE editting/guibuilding is forbidden.

Definition at line 942 of file TGClient.cxx.

◆ SetRoot()

void TGClient::SetRoot ( TGWindow * root = nullptr )
