java - Play/Pause Multiple MediaViews With One Controller JavaFX FXML -


at moment have single scene multiple mediaviews, each own play , pause buttons, in fxml. wondering if there way play/pause ever mediaview had button clicked without making play/pause controller each mediaview. below example of tedious way not wish with.

the fxml

<stackpane alignment="center">                         <mediaview fx:id="mediaview" styleclass="mediaview">                             <mediaplayer>                                 <mediaplayer fx:id="mediaplayer" autoplay="false">                                     <media>                                         <media source="@../vid/vid1.mp4"/>                                     </media>                                 </mediaplayer>                             </mediaplayer>                         </mediaview>                          <button fx:id="btn_play1" onaction="#handleplay1" alignment="center" styleclass="btn_play"/>                         <button fx:id="btn_pause1" onaction="#handlepause1" alignment="center" styleclass="btn_pause" visible="false"/> </stackpane>  <stackpane alignment="center">                         <mediaview fx:id="mediaview2" styleclass="mediaview">                             <mediaplayer>                                 <mediaplayer fx:id="mediaplayer2" autoplay="false">                                     <media>                                         <media source="@../vid/vid2.mp4"/>                                     </media>                                 </mediaplayer>                             </mediaplayer>                         </mediaview>                          <button fx:id="btn_play2" onaction="#handleplay2" alignment="center" styleclass="btn_play"/>                         <button fx:id="btn_pause2" onaction="#handlepause2" alignment="center" styleclass="btn_pause" visible="false"/>

the controller

@fxml private void handlepause1(actionevent event) throws ioexception {     mediaplayer.pause();     btn_pause1.setvisible(false);     btn_play1.setvisible(true);  }  @fxml private void handleplay1(actionevent event) throws ioexception {     mediaplayer.play();     btn_play1.setvisible(false);     btn_pause1.setvisible(true);     mediaactive = true;  }  @fxml private void handlepause2(actionevent event) throws ioexception {     mediaplayer1.pause();     btn_pause2.setvisible(false);     btn_play2.setvisible(true);  }  @fxml private void handleplay2(actionevent event) throws ioexception {     mediaplayer1.play();     btn_play2.setvisible(false);     btn_pause2.setvisible(true);     mediaactive = true;  }

consider creating custom component media view buttons.

the basic idea looks like

package application;  import java.io.ioexception;  import javafx.beans.namedarg; import javafx.fxml.fxml; import javafx.fxml.fxmlloader; import javafx.beans.property.readonlyobjectproperty ; import javafx.scene.control.button; import javafx.scene.layout.stackpane; import javafx.scene.media.mediaplayer;  public class controlledmediaview extends stackpane {       @fxml     private mediaplayer mediaplayer ;      @fxml     private button playbutton ;      @fxml     private button pausebutton ;      public controlledmediaview(@namedarg("mediaurl") string mediaurl) throws ioexception {         fxmlloader loader = new fxmlloader(getclass().getresource("controlledmediaview.fxml"));         loader.setroot(this);         loader.setcontroller(this);         loader.getnamespace().put("mediaurl", mediaurl);         loader.load();     }      public void initialize() {         playbutton.visibleproperty().bind(mediaplayer.statusproperty().isnotequalto(mediaplayer.status.playing));         pausebutton.visibleproperty().bind(mediaplayer.statusproperty().isequalto(mediaplayer.status.playing));     }      @fxml     private void pause() {         mediaplayer.pause();     }      @fxml     private void play() {         mediaplayer.play();     }      public readonlyobjectproperty<mediaplayer.status> statusproperty() {         return mediaplayer.statusproperty();     }      public final mediaplayer.status getstatus() {         return statusproperty().get();     }  }

with controlledmediaview.fxml (in same package):

<?xml version="1.0" encoding="utf-8"?>  <?import javafx.scene.layout.stackpane?> <?import javafx.scene.media.media?> <?import javafx.scene.media.mediaplayer?> <?import javafx.scene.media.mediaview?>  <fx:root xmlns:fx="http://javafx.com/fxml/1" type="stackpane">     <mediaview fx:id="mediaview" styleclass="mediaview">         <mediaplayer>             <mediaplayer fx:id="mediaplayer" autoplay="false">                 <media>                     <media source="${mediaurl}" />                 </media>             </mediaplayer>         </mediaplayer>     </mediaview>      <button fx:id="playbutton" onaction="#play" alignment="center" styleclass="btn_play" />     <button fx:idf="pausebutton" onaction="#pause" alignment="center" styleclass="btn_pause" /> </fx:root>

then main fxml can do

<?xml version="1.0" encoding="utf-8"?>  <?import application.controlledmediaview?>  <!-- ... -->  <controlledmediaview mediaurl="@../vid/vid1.mp4"/> <controlledmediaview mediaurl="@../vid/vid2.mp4"/>  <!-- ... -->

you may need work little make sure urls being communicated correctly; if want use scenebuilder need package controlledmediaview , fxml jar file , import scenebuilder.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
