Due to time limitations I cannot # provide any assistance in building Consed. Even if you do not # modify the source, you may introduce errors due to using a # different version of the compiler, a different version of motif, # different versions of other libraries than I used, etc. For this # reason, if you discover Consed bugs, I can only offer help with # those bugs if you first reproduce those bugs with an executable # provided by me--not an executable you have built. # # Modifying Consed is also difficult. Although Consed is modular, # some modules are used by many other modules. Thus making a change # in one place can have unforeseen effects on many other features. # It may takes months for you to notice these other side-effects # which may not seen connected at all. It is not feasable for me to # provide help with modifying Consed sources because of the # potentially huge amount of time involved. # #*****************************************************************************/ #include "guiQuit.h" #include "guiQuitTypes.h" #include "guiapp.h" #include #include #include #include #include "assert.h" #include "handleWindowManagerDelete.h" guiQuit :: guiQuit() {} void guiQuit :: popupAndGetAnswer(etypeQuit& eWhatQuittingUserWantsToDo ) { Arg aArg[100]; int nArgs; XmStringTable xmStringList; int n; widPopupShell_ = XtVaCreatePopupShell("consed", topLevelShellWidgetClass, GuiApp::pGetGuiApp()->widGetTopLevel(), XmNdeleteResponse, XmDO_NOTHING, NULL ); handleWindowManagerDelete( widPopupShell_ ); // the immediate child of the application shell is a // main window Widget widMainWin = XtVaCreateManagedWidget("mainwin", xmMainWindowWidgetClass, widPopupShell_, XmNancestorSensitive, True, NULL ); // // create the form widget // nArgs = 0; XtSetArg(aArg[nArgs],XmNshadowThickness,0); nArgs++; XtSetArg(aArg[nArgs],XmNborderWidth,0); nArgs++; Widget widForm = XmCreateForm(widMainWin, "form", aArg, nArgs); XtManageChild(widForm); Widget widMessageLabel = XtVaCreateManagedWidget( "Warning--there are unsaved edits", xmLabelWidgetClass, widForm, XmNtopAttachment, XmATTACH_FORM, XmNtopOffset, 10, XmNrightAttachment, XmATTACH_FORM, XmNrightOffset, 40, XmNtraversalOn, False, XmNleftAttachment, XmATTACH_FORM, XmNrightAttachment, XmATTACH_FORM, XmNleftOffset, 40, XmNrightOffset, 40, NULL ); Widget widSaveBeforeQuitting = XtVaCreateManagedWidget( "Save Before Quitting", xmPushButtonWidgetClass, widForm, XmNtopAttachment, XmATTACH_WIDGET, XmNtopWidget, widMessageLabel, XmNrightAttachment, XmATTACH_FORM, XmNrightOffset, 40, XmNtraversalOn, False, XmNleftAttachment, XmATTACH_FORM, XmNrightAttachment, XmATTACH_FORM, XmNleftOffset, 40, XmNrightOffset, 40, NULL ); XtAddCallback(widSaveBeforeQuitting, XmNactivateCallback, (XtCallbackProc )cbGuiQuit, this); Widget widQuitWithoutSaving = XtVaCreateManagedWidget( "Quit Without Saving and Discard .wrk File", xmPushButtonWidgetClass, widForm, XmNtopAttachment, XmATTACH_WIDGET, XmNtopWidget, widSaveBeforeQuitting, XmNtopOffset, 10, XmNrightAttachment, XmATTACH_FORM, XmNrightOffset, 40, XmNtraversalOn, False, XmNleftAttachment, XmATTACH_FORM, XmNrightAttachment, XmATTACH_FORM, XmNleftOffset, 40, XmNrightOffset, 40, NULL ); XtAddCallback(widQuitWithoutSaving, XmNactivateCallback, (XtCallbackProc )cbGuiQuit, this); Widget widQuitWithoutSavingButSaveEditHistory = XtVaCreateManagedWidget( "Quit Without Saving But Save .wrk File", xmPushButtonWidgetClass, widForm, XmNtopAttachment, XmATTACH_WIDGET, XmNtopWidget, widQuitWithoutSaving, XmNtopOffset, 10, XmNrightAttachment, XmATTACH_FORM, XmNrightOffset, 40, XmNtraversalOn, False, XmNleftAttachment, XmATTACH_FORM, XmNrightAttachment, XmATTACH_FORM, XmNleftOffset, 40, XmNrightOffset, 40, NULL ); XtAddCallback(widQuitWithoutSavingButSaveEditHistory, XmNactivateCallback, (XtCallbackProc )cbGuiQuit, this); Widget widCancel = XtVaCreateManagedWidget( "Cancel", xmPushButtonWidgetClass, widForm, XmNtopAttachment, XmATTACH_WIDGET, XmNtopWidget, widQuitWithoutSavingButSaveEditHistory, XmNtopOffset, 10, XmNrightAttachment, XmATTACH_FORM, XmNrightOffset, 40, XmNtraversalOn, False, XmNleftAttachment, XmATTACH_FORM, XmNrightAttachment, XmATTACH_FORM, XmNleftOffset, 40, XmNrightOffset, 40, XmNbottomOffset, 10, NULL ); XtAddCallback(widCancel, XmNactivateCallback, (XtCallbackProc )cbGuiQuit, this); // pop it all up // Note: if you do this any earlier, the bottom of the dialog will be // off the screen since it grows downward after being popped up.
