C++ (Cpp) CMap::SetZoom Examples

Example #1

File: mainmap.cpp Project: pol51/colobot

void CMainMap::ZoomMap()
{
    CWindow*    pw;
    CMap*       pm;
    CSlider*    ps;
    float       zoom;

    pw = static_cast<CWindow*>(m_interface->SearchControl(EVENT_WINDOW1));
    if (pw == nullptr)
        return;
    pm = static_cast<CMap*>(pw->SearchControl(EVENT_OBJECT_MAP));
    if (pm == nullptr)
        return;

    ps = static_cast<CSlider*>(pw->SearchControl(EVENT_OBJECT_MAPZOOM));
    if (ps == nullptr)
        return;


    zoom = ps->GetVisibleValue();
    zoom = powf(zoom, 2.0f);
    zoom = ZOOM_MIN+zoom*(ZOOM_MAX - ZOOM_MIN);
    pm->SetZoom(zoom);

    DimMap();
}

Example #2

File: mainmap.cpp Project: pol51/colobot

void CMainMap::ZoomMap(float zoom)
{
    CWindow*    pw;
    CMap*       pm;
    CSlider*    ps;

    pw = static_cast<CWindow*>(m_interface->SearchControl(EVENT_WINDOW1));
    if (pw == nullptr)
        return;
    pm = static_cast<CMap*>(pw->SearchControl(EVENT_OBJECT_MAP));
    if (pm == nullptr)
        return;

    ps = static_cast<CSlider*>(pw->SearchControl(EVENT_OBJECT_MAPZOOM));
    if (ps == nullptr)
        return;

    if (zoom < ZOOM_MIN)
        zoom = ZOOM_MIN;
    if (zoom > ZOOM_MAX)
        zoom = ZOOM_MAX;
    pm->SetZoom(zoom);

    DimMap();
}

Example #3

File: mainmap.cpp Project: pol51/colobot

void CMainMap::SetFixParam(float zoom, float ox, float oy, float angle,
                           int mode, bool bDebug)
{
    CWindow*    pw;
    CMap*       pm;

    pw = static_cast<CWindow*>(m_interface->SearchControl(EVENT_WINDOW1));
    if (pw == nullptr)
        return;

    pm = static_cast<CMap*>(pw->SearchControl(EVENT_OBJECT_MAP));
    if (pm == nullptr)
        return;

    pm->SetZoom(zoom);
    pm->SetOffset(ox, oy);
    pm->SetAngle(angle);
    pm->SetMode(mode);
    pm->SetDebug(bDebug);
