How to select date/time under the cursor

Hi!

Just wanted to ask what's the proper way to select the time/day block under the mouse pointer on a right mouse button click. Let's say, I've got this:

    CPoint ptHit(wParam);
    XTP_CALENDAR_HITTESTINFO hitInfo;
    BOOL bHitTest = GetCalendarCtrl().GetActiveView()->HitTest(ptHit, &hitInfo);

    if (XTP_NC_CALENDARCONTEXTMENU == Event || XTP_NC_CALENDARRBUTTONDOWN == Event)
    {
        CXTPCalendarViewEvents* selectedEvents = GetCalendarCtrl().GetActiveView()->GetSelectedViewEvents();
        selectedEvents->RemoveAll();

        CXTPCalendarControl::CUpdateContext updateContext(&GetCalendarCtrl(), xtpCalendarUpdateRedraw);
        GetCalendarCtrl().GetActiveView()->SetSelection(hitInfo.dt, hitInfo.dt);
        GetCalendarCtrl().RedrawControl();
    }

But this has 2 problems:

1) if the focus wasn't in the control, then it's not updated/redrawn properly to reflect the new selection
2) if an event is selected and you click anywhere else, the event is still selected till the next click (at least it appear to be drawn selected, maybe it's all one problem)

Thanks in advance,

Sorry, I'm not sure how that helps - I'm looking at the CalendarDemo sample, right?

Hmm, but what I want is to *select* the time slot under the cursor. And it works, except the control is not redrawn till I select something else. Tooltips only show me a hit test?

mdoubson wrote: Right - but this hit test fill tooltip with some event-related data - so this is example of data retriving on fly (or more precise - on mouse move)

Yes, but that's not what I need I need to select a block in the calendar control that doesn't have an event. Just an empty slot. And I can do that using the code I show above, however, the control is not updating that block (doesn't repaint it) until I force and invalidate or similar. The block is selected ok though, because I can see that the time/date combination is correct (in my editor).

Ok, just to illustrate - change CalendarDemoView.cpp around line 757 to:

    else if (XTP_NC_CALENDARCONTEXTMENU == Event)
    {
        CXTPCalendarControl::CUpdateContext updateContext(&GetCalendarCtrl(), xtpCalendarUpdateRedraw);
        GetCalendarCtrl().GetActiveView()->SetSelection(hitInfo.dt, hitInfo.dt);
        GetCalendarCtrl().RedrawControl();

        if (bHitTest)
        {

and then try right-clicking in the control and adding a new event. See, the time is picked up correctly, but the control is not redrawn properly.

I'm trying the day view for now... thanks!

I think that the best for DayView is - click on timescale on desired interval and after this - right click - and select add new event on menu.

void CCalendarDemoView::OnEvent_Calendar(XTP_NOTIFY_CODE Event, WPARAM wParam, LPARAM lParam) {

UNREFERENCED_PARAMETER(lParam);

if (!GetCalendarCtrl().GetActiveView()) return;

CPoint ptHit(wParam);

XTP_CALENDAR_HITTESTINFO hitInfo;

BOOL bHitTest = GetCalendarCtrl().GetActiveView()->HitTest(ptHit, &hitInfo);

................................................................

else if (XTP_NC_CALENDARLBUTTONDBLCLICK == Event) {

if (bHitTest && hitInfo.pViewEvent) { // mouse double clicked - show event edit dialog }

//We come here but need to extend this case to cover TimeScale area (now it covers DayArea and DayHeader only!)

...........................

I tried it - working precise in the term of timescale interval - I updated my static demo so you can play yourself with this case:

 

I run it now directly from archive - switch to DayView and click Right Mouse button in TimeScale

If you have event - you can select it inside cell. But if you don't have event - pick time interval on timescale is very user-friendly and intuitive.

in MFC:

CPoint ptHit(wParam);

XTP_CALENDAR_HITTESTINFO hitInfo;

BOOL bHitTest = GetCalendarCtrl().GetActiveView()->HitTest(ptHit, &hitInfo);

..........................................

{

AfxMessageBox(hitInfo.dt.Format(_T("%H:%M:%S A, %B %d, %Y")));

..........................................

So you need to pass it to editor

 

try to simulate left click in your handler

mouse_event(MOUSEEVENTF_LEFTDOWN, ptHit.x, ptHit.y, 0, 0);

mouse_event(MOUSEEVENTF_LEFTUP, ptHit.x, ptHit.y, 0, 0);

Good. Send me your solution - may be we can use it as option

So you did not find a way to do it on right buton down event only - hightlight + context menu in one action...

You can also make this (Highlighting) action optional if use extra condition (both mouse buttons pressed)

No, I haven't tried the sample, but looks good :) I'm waiting for 13.1...
