swing - Java synth - How to apply solid color to button background -


i trying obtain simple flat button using synth xml in java. button should contain solid color background , text no other effects.

i have checked tutorials , implemented below solution need provide solid color background image button.

    <state>         <imagepainter method="buttonbackground" path="images/button_press.png" sourceinsets="10 10 10 10"/>         <font name="dialog" size="16"/>         <color type="text_foreground" value="#ffffff"/>     </state>

but per synth documentation here should able provide background color button instead of using image. have tried below xml settings same. not applying background buttons. whereas applying provided color text.

    <state>         <font name="verdana" size="14"/>         <color value="#ff0000" type="background"/>         <color value="#000000" type="text_foreground"/>     </state>

can check , me find out mistake have done or there other solution this?

i guess need use <opaque value="true" /> paint jbutton's background:

button.xml

<synth>   <style id="default">     <font name="dialog" size="16" />    </style>   <bind style="default" type="region" key=".*" />    <style id="buttontest">     <opaque value="true" />     <insets top="10" bottom="10" left="10" right="10" />     <state>       <font name="verdana" size="14" />       <color type="background" value="#ff0000" />       <color type="text_foreground" value="#000000" />     </state>     <state value="mouse_over">       <color type="background" value="orange" />       <color type="text_foreground" value="white" />     </state>     <state value="pressed">       <color type="background" value="green" />       <color type="text_foreground" value="white" />     </state>   </style>   <bind style="buttontest" type="region" key="button" /> </synth>

synthbuttontest.java

import java.awt.*; import javax.swing.*; import javax.swing.plaf.synth.*;  public class synthbuttontest {   public jcomponent makeui() {     jpanel p = new jpanel();     p.add(new jbutton("jbutton1"));     p.add(new jbutton("jbutton2"));     p.add(new jbutton("jbutton3"));     return p;   }   public static void main(string... args) {     eventqueue.invokelater(() -> {       try {         class<?> c = synthbuttontest.class;         synthlookandfeel synth = new synthlookandfeel();         synth.load(c.getresourceasstream("button.xml"), c);         uimanager.setlookandfeel(synth);       } catch (exception ex) {         ex.printstacktrace();       }       jframe f = new jframe();       f.setdefaultcloseoperation(windowconstants.exit_on_close);       f.getcontentpane().add(new synthbuttontest().makeui());       f.setsize(320, 240);       f.setlocationrelativeto(null);       f.setvisible(true);     });   } }

i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
