Getting mouse click location of a label in qt

跟風遠走 提交于 2019-12-04 02:45:12
I googled around and found this forum thread in which the OP seems to have had the exact problem I am having. The question is, how would I inherit from QLabel and reimplement the mousepressed event? I'm guessing it would be something like this: class CustomLabel : public QLabel { public: //what about the constructors? void mousePressEvent ( QMouseEvent * ev ); } void CustomLabel::mousePressEvent ( QMouseEvent * ev ) { QPoint = ev->pos(); //I want to have another function get the event position. //How would I achieve this? It's void! //Is there perhaps some way to set up a signal and slot with

Do I need an api key to get last known location in Android with Google Play Services?

被刻印的时光 ゝ 提交于 2019-12-04 02:41:12
问题 I just recently started learning Android and am working on small projects to learn the essentials I need for to work on a larger project I have coming up. I need to get the users last know location. I went through this tutorial, and it wouldn't connect to play services. Do I need an api key to get the last known location? And also what is the easiest way to implement location awareness in Android? 回答1: You need not to give any API key to fetch last known Location. API key is needed when

How do I get the coordinates of a map on tap with MapFragment (not MapView)?

本秂侑毒 提交于 2019-12-04 02:24:35
I have searched around on how to get the coordinates of a location when the map is tapped. However, most, if not all the examples require a MapView as a parameter. For example: public boolean onTap(GeoPoint p, MapView map){ if ( isPinch ){ return false; }else{ Log.i(TAG,"TAP!"); if ( p!=null ){ handleGeoPoint(p); return true; // We handled the tap }else{ return false; // Null GeoPoint } } } @Override public boolean onTouchEvent(MotionEvent e, MapView mapView) { int fingers = e.getPointerCount(); if( e.getAction()==MotionEvent.ACTION_DOWN ){ isPinch=false; // Touch DOWN, don't know if it's a

Currently on my Windows 7 machine, it is C:\Program Files (x86)\EasyPHP-5.3.8.1\www I want to point it into another location on drive D, says D:\code How would I do that? You need to right click on the icon on the Easyphp icon on the taskbar and select configuration->Apache. This will open httpd.conf in a notepad window.

1、两个tomcat互相影响: 改掉其中一个跟前一个一样的端口号;,重启不再影响; 2、微信公众号提示redirect-url 域名不一致,修改 nginx.conf 中的upstream名称为公众号后台填写的域名,即可解决; 3、存放路径:、usr/local/nginx 这个是nginx的程序路径;对应的还有安装包路径,除配置信息外,安装这个插件那个插件都是在安装路径的包里; 4、ssl的配置,ssl.conf 这名字都是自己起的:路径: cd /usr/local/nginx/conf/vhost/ server { listen 443 ssl; server_name www.lpwyx.com; ssl_certificate /usr/local/nginx/cert/2720230_lpwyx.com.pem; ssl_certificate_key /usr/local/nginx/cert/2720230_lpwyx.com.key; ssl_session_timeout 5m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers AESGCM:ALL:!DH:!EXPORT:!RC4:+HIGH:!MEDIUM:!LOW:!aNULL:!eNULL; ssl_prefer_server_ciphers on;

Proximity alert for locations saved at server

只谈情不闲聊 提交于 2019-12-04 00:56:55
I did some search but could not find a suitable answer. My App should compare with multiple locations for proximity. This means I will not be able to save all the locations into my app to confirm the proximity using locationManager. I want the proximity confirmation to be done in the server What would be the best way to implement this? Would it be sensible if the app asks for proximity confirmation every time the devices moves around? I would try a different approach, since location updates from GPS are made once per second, and I don't think it's a good idea to ask the server each second for

NSLocationWhenInUseUsageDescription warning but i have already added it

喜夏-厌秋 提交于 2019-12-04 00:48:54
While i have already added NSLocationWhenInUseUsageDescription I keep receiving this warning This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSLocationWhenInUseUsageDescription key with a string value explaining to the user how the app uses this data FYI: I have multiple info.Plist in the app. Not sure what to do? Adding both NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription keys in plist solved my problem. <key>NSLocationAlwaysUsageDescription</key> <string>Your location is required

Enable location services for Android if user chose Never option

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-04 00:27:06
Is there any way to allow location services again for an app (or at least show the dialog) if the user previously chose the option Never? I dont find any way in code to show it again, since i always get LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE in the onResult(..) callback: @Override public void onResult(LocationSettingsResult locationSettingsResult) { final Status status = locationSettingsResult.getStatus(); switch (status.getStatusCode()) { case LocationSettingsStatusCodes.SUCCESS: Log.i(TAG, "All location settings are satisfied."); // startLocationUpdates(); break; case

Android getbearing only returns 0.0. Trying to use to rotate current location icon

问题 This is in part an extension to a previous question: Android programming, mapview locationoverlay: how to change the default blue location dot, with another image I have been working to get the devices location to display on the map (easy with enablemylocation) but I need to replace the default icon (easy enough, sorted that) and then rotate it to correspond to the current device bearing - acquired from GPS, as it needs to be direction of movement, not direction the phone is facing.
