MFC Tab Control Color Change #2





Change Tab Selector? Color




override DrawItem function




void CMainTabCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{

	COLORREF m_select_border_color = RGB(255, 255, 255);
	COLORREF m_select_text_color = RGB(10, 155, 202);
	COLORREF m_unselect_border_color = RGB(255, 255, 255);
	COLORREF m_unselect_text_color = RGB(0, 0, 0);


	int select_index = lpDrawItemStruct->itemID;
	if (select_index < 0) return;

	char tab_text[40];

	TC_ITEM data;
	data.mask = TCIF_TEXT | TCIF_IMAGE;
	data.pszText = tab_text;
	data.cchTextMax = 39;

	// 선택된 탭의 정보를 얻는다.
	if (!GetItem(select_index, &data)) return;

	CDC *pDC = CDC::FromHandle(lpDrawItemStruct->hDC);
	CRect rect = lpDrawItemStruct->rcItem;

	// Tab이 그려진 테두리의 두께만큼 위치를 보정한다.
	rect.top += ::GetSystemMetrics(SM_CYEDGE);

	pDC->SetBkMode(TRANSPARENT);

	// 탭이 선택된 정보에 따라 배경색을 칠해준다.
	if (select_index == GetCurSel()) pDC->FillSolidRect(rect, m_select_border_color);
	else pDC->FillSolidRect(rect, m_unselect_border_color);

	// 이미지를 출력한다.
	CImageList *p_image_list = GetImageList();
	if (p_image_list != NULL && data.iImage >= 0) {
		rect.left += pDC->GetTextExtent(" ").cx;

		IMAGEINFO image_info;
		p_image_list->GetImageInfo(data.iImage, &image_info);
		CRect image_rect(image_info.rcImage);

		p_image_list->Draw(pDC, data.iImage, CPoint(rect.left, rect.top), ILD_TRANSPARENT);
		rect.left += image_rect.Width();
	}

	CFont *p_old_font = NULL;

	if (select_index == GetCurSel()){
		// 선택된 탭이라면...
		pDC->SetTextColor(m_select_text_color);

		// 텍스트의 위치를 보정하여 선택된 느낌이 강조되도록 만든다.
		rect.top -= ::GetSystemMetrics(SM_CYEDGE);

	}
	else {

		pDC->DrawText(tab_text, rect, DT_SINGLELINE | DT_BOTTOM | DT_CENTER);
	}

	pDC->SelectObject(p_old_font);
}



그리고


DrawItem 이벤트를 발생시키기 위하여



Dialog 에서






m_TabCtrl.ModifyStyle(0, TCS_OWNERDRAWFIXED);


를 불러 주어야 한다.

Android Geocoding – Showing User Input Location on Google Map Android API V2



In this article, we will create an Android application which facilitates users to input street address in an EditText and on clicking the find button, application draws corresponding location marker on the Google Map Android API v2 using Google’s Geocoder API.

This application is an upgraded version of the application discussed in the article titled “Android Geocoding – Showing User Input Location on Google Map” where the location is shown in Google Map Android API v1.

This application is developed in Eclipse 4.2.1 with ADT plugin ( 21.0.0 ) and Android SDK ( 21.0.0 ) and is tested in a real Android Phone with Android 2.3.6  ( GingerBread ).

1. Download and configure Google Play Services Library in Eclipse

Please follow the given below link to setup Google Play Service library in Eclipse.

http://developer.android.com/google/play-services/setup.html

2. Create a new Android Application Project namely “LocationGeocodingV2″

Create new Android application project

Figure 1 : Create new Android application project

3. Configure Android Application Project

Configure Android Application Project

Figure 2 : Configure Android Application Project

4. Design Application Launcher Icon

Figure 3 : Design Application Launcher Icon

5. Create a blank activity

Create a blank activity

Figure 4 : Create a blank activity

6. Enter Main Activity Details

Enter Main Activity Details

Figure 5 : Enter Main Activity Details

7. Link to Google Play Service Library

Link to Google Play Services Library

Figure 6 : Link to Google Play Services Library

8. Get the API key for Google Maps Android API v2

We need to get an API key from Google to use Google Maps in Android application. Please follow the given below link to get the API key for Google Maps Android API v2.

https://developers.google.com/maps/documentation/android/start

9. Add Android Support library to this project

By default, Android support library (android-support-v4.jar ) is added to this project by Eclipse IDE to the directory libs. If it is not added, we can do it manually by doing the following steps :

  • Open Project Explorer by Clicking “Window -> Show View -> Project Explorer”
  • Right click this project
  • Then from popup window, Click “Android Tools -> Add Support Library “

10. Update the file AndroidManfiest.xml
