我使用Qt 5.2.1窗口(Qt Creator的3.0.1)QML:使用滚动型导致不正确的显示元素
我有一个自定义QML组件,它的工作原理,当我加载在精到矩形:
import QtQuick 2.0
import QtQuick.Controls 1.1
Rectangle {
id: mainRectangle
anchors.fill: parent
Loader {
anchors.top: parent.top;
anchors.left: parent.left;
anchors.right: parent.right;
id: ld01;
onLoaded: {
ld01.visible = true;
anchors.top = parent.top;
}
}
Loader {
anchors.top: ld01.bottom;
anchors.left: parent.left;
anchors.right: parent.right;
id: ld02;
onLoaded: {
anchors.top = ld01.bottom;
ld02.visible = true;
}
}
Component.onCompleted: {
ld01.setSource("View_item2.qml");
ld02.setSource("View_item2.qml");
}
}
但是,当我试图把它放在一个ScrollView中,我的组件的元素被移动到某个地方。我应该实施什么样的技巧来正确使用ScrollView?
ScrollView {
id: mainTabLayout
anchors.fill: parent
anchors.margins: 4
//here I put a code from above (except imports, of course)
}
组件代码如下:
import QtQuick 2.1
import QtQuick.Controls 1.1
import QtQuick.Layouts 1.0
Rectangle {
id: slv_layout
objectName: "itemColumnLayout"
anchors.left: parent.left
anchors.right: parent.right
anchors.margins: 1
property int minimal_height: 200
height: 400
color: "green"
MouseArea {
property bool is_pressed: false
property int initial_y: 0
property int proposed_y: 0
id: resizeStick
enabled: true
anchors.bottom: parent.bottom
height: 10
width: parent.width
hoverEnabled: true
onEntered: {
cursorShape = Qt.SizeVerCursor;
}
onPressed: {
is_pressed = true;
initial_y = mouseY;
}
onReleased: {
is_pressed = false;
}
onMouseYChanged: {
if (is_pressed) {
proposed_y = slv_layout.height + mouseY - initial_y;
if (proposed_y >= slv_layout.minimal_height) {
slv_layout.height += (mouseY - initial_y);
initial_y = mouseY;
}
}
}
}
Text {
id: slvTitle
text: "device name"
anchors.top: parent.top
anchors.left: parent.left
anchors.margins: 2
}
Rectangle {
anchors.top: slvTitle.bottom
anchors.left: parent.left
anchors.bottom: parent.bottom
anchors.right: parent.right
anchors.topMargin: 2
color: "blue"
Button {
id: slv_butt_run;
objectName: "slv_butt_run"
width: 60
height: width
text: "Run"
anchors.top: parent.top
anchors.left: parent.left
anchors.margins: 2
}
Button {
id: slv_butt_settings;
objectName: "slv_butt_settings"
width: 60
height: width
text: "Settings"
anchors.top: parent.top
anchors.left: slv_butt_run.right
anchors.margins: 2
}
Button {
id: slv_butt_stop;
objectName: "slv_butt_stop"
width: 60
height: width
text: "Stop"
anchors.top: slv_butt_run.bottom
anchors.left: parent.left
anchors.margins: 2
}
Button {
id: slv_butt_expand;
objectName: "slv_butt_expand"
width: 60
height: width
text: "Expand"
anchors.top: slv_butt_settings.bottom
anchors.left: slv_butt_stop.right
anchors.margins: 2
}
TextArea {
id: slv_log_area
anchors.left: slv_butt_expand.right
anchors.top: parent.top
anchors.bottom: parent.bottom
anchors.right: parent.right
anchors.margins: 3
}
}
}

我不能重现你的bug,它对我来说工作得很好。你能举一个你的问题的最小例子吗? – BlueMagma
