    <p>[UPDATE] I noticed that an invalidate() would be good but it didnt change something! So i put in the whole optionlayout with the creation of the table and the slider + labels. The backbutton is just a textbutton added to the end of the table. I know its a long code but i seems to be needed. <br></p> <p>I created a slider like this as i know that the min width of the background is used for the slider width:</p> <pre><code>public OptionScreen(MainClass game) { super(game); preference = new PreferencesHelper(); font = this.getDefaultFont(25); this.table = new Table(); if (Config.DEBUG) this.table.debug(); // add volumenlabel LabelStyle style = new LabelStyle(font, Color.WHITE); volumenLabel = new Label(Config.VOLUMEN_LABLE, style); table.add(volumenLabel).colspan(2); table.row(); // add slider Skin skin = new Skin(); skin.add("sliderbackground", this.game.manager.get("data/sliderbackground.png")); skin.add("sliderknob", this.game.manager.get("data/sliderknob.png")); SliderStyle sliderStyle = new SliderStyle(); sliderStyle.background = skin.getDrawable("sliderbackground"); sliderStyle.background.setMinWidth(600f); sliderStyle.knob = skin.getDrawable("sliderknob"); volumenSlider = new Slider(0f, 1f, 0.1f, false, sliderStyle); volumenSlider.setValue(preference.getVolumen()); // load current volumen volumenSlider.addListener(new ChangeListener() { @Override public void changed(ChangeEvent event, Actor actor) { volumeValue.setText(String.format("%.01f", volumenSlider.getValue())); // sett the preference preference.setVolumen(volumenSlider.getValue()); } }); // add volslider to stage table.add(volumenSlider); volumenLabel.invalidate(); // table style = new LabelStyle(font, Color.WHITE); // set current volumen volumeValue = new Label( String.format("%.01f", volumenSlider.getValue()), style); volumenLabel.setAlignment(2); table.add(volumeValue).width(50f); table.row(); initBackButton(); // init table table.setPosition(Config.VIRTUAL_VIEW_WIDTH / 2, Config.VIRTUAL_VIEW_HEIGHT / 2 - Config.BLOCK_SIZE * 10); // add a nice fadeIn to the whole table :) table.setColor(0, 0, 0, 0f); table.addAction(Actions.fadeIn(2f)); // alpha fade table.addAction(Actions.moveTo(Config.VIRTUAL_VIEW_WIDTH / 2, Config.VIRTUAL_VIEW_HEIGHT / 2, 2f)); // move to center of the // screen // add to stage this.stage.addActor(table); } </code></pre> <p>It's inside a table with no width or such. I already took a look if the width is sett and if the calculation for the prefWidth of the slider does take my 600. </p> <pre><code>Math.max(style.knob == null ? 0 : style.knob.getMinWidth(), style.background.getMinWidth()) </code></pre> <p>this is the calculation for the width of the slider inside the Sliderclass. If i calculate that and log it, i get the 600. <br> Everything seems to me right but the slider is way to small for the 600 i sett.<br> Background and knobtextures are 24x24.<br> So i hope you guys can tell me what i am doing wrong. <img src="https://i.stack.imgur.com/eIDbM.jpg" alt="silder"></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
