How can I set a default value in a ComboBox
using FXML?
<ComboBox fx:id="cbo_Bacteriologie_Aesculine" prefHeight="21.0" prefWidth="105.0" GridPane.columnIndex="1" GridPane.rowIndex="0">
<items>
<FXCollections fx:factory="observableArrayList">
<String fx:value="NVT" />
<String fx:value="Bezig" />
<String fx:value="Positief" />
<String fx:value="Negatief" />
</FXCollections>
</items>
</ComboBox>
I want NVT
to be selected by default. I tried adding selected="selected"
and such but don't seem to find the right syntax.
Is it possible to edit the listed items using Scene Builder? I can't seem to find it.
By default, ComboBox widget do not set a value. If you want to set any default value to ComboBox, use 'setValue' method. For example: ObservableList<String> hobbies = FXCollections.
Use this:
<ComboBox>
<items>
<FXCollections fx:factory="observableArrayList">
<String fx:value="NVT" />
<String fx:value="Bezig" />
<String fx:value="Positief" />
<String fx:value="Negatief" />
</FXCollections>
</items>
<value>
<String fx:value="NVT" />
</value>
</ComboBox>
I don't think it's possible in the FXML. You will need to do it in the initialization of the component, in the controller, for example using the following line cbo_Bacteriologie_Aesculine.getSelectionModel().setSelectedIndex(1);
for selecting the element Bezig.
But if you find a way to do it in FXML, I am interested.
EDIT : It is possible in FXML. You can see it in Guedolino's answer (https://stackoverflow.com/a/14436371/1344424), which should become the right answer to this question.
