Qml小白求助 :-) 打擾大噶了哇
想實作一個功能，即點擊Button后，Button所對應的Image變為藍色，其余均為白色；當滑鼠移至Button上方時，若Image為藍色則不執行if陳述句所指定操作，否則變為灰色；當滑鼠離開Button時，若Image為藍色則不執行if陳述句所指定操作，否則變為白色。
但執行后，盡管Image為藍色，滑鼠移至Button上方或離開Button均會改變Image的顏色（即無視if條件的限制）。
以下為該功能相應代碼：
Button {
anchors.fill: parent
hoverEnabled: true
background: transparent
ToolTip.visible: hovered
ToolTip.text: qsTr("帶狀航線")
Image {
id: stripCourseImage
z: 5
width: stripCourseBtn.width * 0.4
height: stripCourseBtn.height * 0.4
mipmap: true
anchors.centerIn: parent
source: "Images/paper plane-fill white.svg"
}
MouseArea {
anchors.fill: parent
hoverEnabled: true
onClicked: {
wayPointFlightImage.source = "Images/paper plane-fill white.svg"
aerialPhotographyImage.source = "Images/paper plane-fill white.svg"
obliquePhotographyImage.source = "Images/paper plane-fill white.svg"
stripCourseImage.source = "Images/paper plane-fill blue.svg"
}
onEntered: {
if(wayPointFlightImage.source != "Images/paper plane-fill blue.svg") {
wayPointFlightImage.source = "Images/paper plane-fill white.svg"
}
if(aerialPhotographyImage.source != "Images/paper plane-fill blue.svg") {
aerialPhotographyImage.source = "Images/paper plane-fill white.svg"
}
if(obliquePhotographyImage.source != "Images/paper plane-fill blue.svg") {
obliquePhotographyImage.source = "Images/paper plane-fill white.svg"
}
if(stripCourseImage.source != "Images/paper plane-fill blue.svg") {
stripCourseImage.source = "Images/paper plane-fill grey.svg"
}
}
onExited: {
if(stripCourseImage.source != "Images/paper plane-fill blue.svg") {
stripCourseImage.source = "Images/paper plane-fill white.svg"
}
}
}
}
