我的边框上有以下元素,但我希望白色背景位于按钮后面。我怎么能这样做?
我有这个
但是想要这样的东西
为了设置它,我使用的是fxml。见下文
<VBox prefHeight="200.0" prefWidth="100.0" BorderPane.alignment="CENTER">
<BorderPane.margin>
<Insets bottom="10.0" top="10.0" />
</BorderPane.margin>
<children>
<Label styleClass="text-tab" text="Local Offers" />
<Label styleClass="text-tab-sub" text="My text label with white bg" />
<HBox alignment="CENTER" prefHeight="100.0" prefWidth="200.0">
<children>
<Button mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-shopping" />
</styleClass>
</Button>
<Button layoutX="10.0" layoutY="10.0" mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-eat" />
</styleClass>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</Button>
<Button layoutX="120.0" layoutY="10.0" mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-leisure" />
</styleClass>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</Button>
<Button layoutX="230.0" layoutY="10.0" mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-home" />
</styleClass>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</Button>
<Button layoutX="330.0" layoutY="10.0" mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-health" />
</styleClass>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</Button>
<Button layoutX="430.0" layoutY="10.0" mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-services" />
</styleClass>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</Button>
<Button layoutX="560.0" layoutY="10.0" mnemonicParsing="false" prefHeight="100.0" prefWidth="100.0" text="Button">
<styleClass>
<String fx:value="btn-category" />
<String fx:value="btn-events" />
</styleClass>
<HBox.margin>
<Insets left="10.0" />
</HBox.margin>
</Button>
</children>
<VBox.margin>
<Insets />
</VBox.margin>
</HBox>
</children>
</VBox>
这是我到目前为止应用的css(减去css为每个按钮着色)。
.text-tab {
-fx-font-size: 39;
-fx-background-color: #FFC000;
-fx-font-weight:bold;
-fx-text-fill: #FFFFFF;
-fx-border-radius: 10 10 0 0;
-fx-background-radius: 10 10 0 0;
-fx-padding: 5 10 0 10;
}
.text-tab-sub {
-fx-font-size: 30;
-fx-background-color: #FFFFFF;
-fx-font-weight: bold;
-fx-text-fill: #3B5999;
}
.btn-category {
-fx-border-color:#ffffff;
-fx-border-radius:15;
-fx-border-width:4;
-fx-background-radius:20;
-fx-margin: 10 10 0 0;
}
答案 0 :(得分:2)
这需要一个额外的样式类和另一个CSS规则:
.white-half {
-fx-background-color:linear-gradient(from 0% 0% to 0% 50%, white, white 49%, white 99%, transparent);
}
此CSS规则的上半部分为白色背景,下半部分为透明背景。
现在您需要将此样式类分配给包含HBox
的{{1}}:
Button
接下来,您希望将带有白色背景的<HBox alignment="CENTER" prefHeight="100.0" prefWidth="200.0" styleClass="white-half">
拉伸到整个宽度:
Label
通过将<Label styleClass="text-tab-sub" maxWidth="1.7976931348623157E308" text="My text label with white bg" />
属性设置为maxWidth
来完成此操作。
