tool bar支持按end键后弹出，再按end键后缩回

1. 在Vfx_page.cpp文件中定义全局变量 

//mtk added 

 VfxBool g_isHiddenToolbar = true;

 
2， 修改adjustClient函数，用#if 1标注 

void VfxPage::adjustClient() 

 { 

  VfxFrame *f = getParentFrame(); 

  if(m_pageFlags & FLAGS_IS_TRANSLUCENT) 

  { 

  if(m_pageFlags & FLAGS_IN_IME_LAYOUT) 

  return; 

   

  VFX_MC_TRACE5(VFX_FUNC, TRC_VFX_F5FD630A0FA44B6990DD4AC43AE75B29,  

 "[VfxPage](%x) adjustClient(%d,%d,%dx%d)", this, 0, 0, f->getSize().width, f->getSize().height); 

  setPos(0, 0); 

  setSize(f->getSize()); 

  } 

  else 

  { 

  VfxS32 barH; 

  VfxRect client; 

  VfxSize s; 

  VfxPoint t; 

  if(f->isKindOf(VFX_OBJ_CLASS_INFO(VfxMainScr))) 

  { 

  client = ((VfxMainScr*)f)->getClient(this); 

  } 

  else if(f->isKindOf(VFX_OBJ_CLASS_INFO(VfxPage))) 

  { 

  client = ((VfxPage*)f)->getPageRect(); 

  } 

  else 

  { 

  client.size = f->getSize(); 

  client.origin.x = 0; 

  client.origin.y = 0; 

  } 

   

  s = client.size; 

  t = client.origin; 

  barH = m_topBar->getSize().height; 

  t.y += barH; 

  s.height -= barH; 

  barH = m_bottomBar->getSize().height; 

  if(m_pageFlags & FLAGS_IN_IME_LAYOUT) 

  { 

  VfxS32 *imeOffset = (VfxS32*)getAttachProperty(VFX_PAGE_PROP_ID_IMEOFFSET, sizeof(VfxS32)); 

  VfxS32 imeH = client.size.height - (*imeOffset); 

  if(barH < imeH) 

  barH = imeH; 

  } 

  //mtk added 

  #if 1 

  if(!g_isHiddenToolbar)  

  s.height -= barH; 

  #else 

  s.height -= barH; 

  #endif 

  VFX_MC_TRACE5(VFX_FUNC, TRC_VFX_F5FD630A0FA44B6990DD4AC43AE75B29,  

 "[VfxPage](%x) adjustClient(%d,%d,%dx%d)", this, t.x, t.y, s.width, s.height); 

   

  setRect(VfxRect(t, s)); 

  } 

 }

3. VfxPage::Bar::reposistionBar方法，用#if 1标注 

void reposistionBar(VfxPageBar *bar, VfxPageBarLocationEnum loc, VfxBool noAnimation = VFX_FALSE) 

  { 

  VfxPage *page = VFX_OBJ_DYNAMIC_CAST(bar->getParent(), VfxPage); 

  VFX_ASSERT(page); 

   

  VfxFrame *f = page->getParentFrame(); 

  VfxMainScr *scr = page->getMainScr(); 

  if(bar->getParentFrame() != f) 

  f->addChildFrame(bar); 

  VfxRect client; 

  if(f == scr) 

  { 

  client = scr->getClient(page); 

  } 

  else 

  { 

  client.size = f->getSize(); 

  client.origin = VfxPoint(0, 0); 

  } 

  VfxSize barSize = bar->getSize(); 

  if(noAnimation) 

  { 

  VfxAutoAnimate::begin(); 

  VfxAutoAnimate::setDisable(VFX_TRUE); 

  } 

  // adjust size 

  barSize.width = client.size.width; 

  bar->setSize(barSize); 

  // adjust position  

  if(loc == VFX_PAGE_BAR_LOCATION_TOP) 

  bar->setPos(client.origin.x, client.origin.y); 

  else if(loc == VFX_PAGE_BAR_LOCATION_BOTTOM) 

  { 

  #if 1 

  if(g_isHiddenToolbar) 

  bar->setPos(client.origin.x, client.origin.y + client.size.height); 

  else 

  bar->setPos(client.origin.x, client.origin.y + client.size.height - barSize.height); 

  #else 

  bar->setPos(client.origin.x, client.origin.y + client.size.height - barSize.height); 

  #endif 

  } 

  if(noAnimation) 

  { 

  VfxAutoAnimate::commit(); 

  } 

  bar->setLoc(loc); 

  bar->setRotate(page->getRotate()); 

  } 

  

 4. 修改VfxPage::onKeyInput的默认实现，用#if 1标注 

 VfxBool VfxPage::onKeyInput(VfxKeyEvent &event) 

 { 

  if (event.keyCode == VFX_PAGE_KEY_BACK && 

  event.type == VFX_KEY_EVENT_TYPE_DOWN) 

  { 

  back(); 

  return VFX_TRUE; 

  } 

 #if 1 

  if (event.keyCode == VFX_KEY_CODE_END && event.type == VFX_KEY_EVENT_TYPE_DOWN) 

  { 

  g_isHiddenToolbar = !g_isHiddenToolbar; 

  //toggleBar(VFX_PAGE_BAR_LOCATION_BOTTOM, g_isHiddenToolbar); 

  reposistionBars(VFX_FALSE); 

  return VFX_TRUE; 

  } 

 #endif 

   

  return VfxControl::onKeyInput(event); 

 }

另外，如果不用做弹上弹下的动画，那么前面的2，3步均可不做修改。可以在onKeyInput里面，把call reposistionBars换成call toggleBar。
