Settings on top bezel bb10 - qml

UPDATE
I wanna implement the setting by swiping the top bezel, here's my code am I doing this right? Currently this doesn't work. I wanna know how to implement it. Where should I put the code for it, and what do I lack of so that it'll work?

}
And here's the topsettings.qml
MenuDefinition {
settingsAction: SettingsActionItem {
imageSource: "asset:///images/navbar_icon_settings.png"
onTriggered: {
cppObj.onSettingsClicked();
}
}
Settings is not displayed:

Your code looks good: the only issue is that you try to define your Menu.definition in a Page, but you should be defining it in a Pane. See here for example: https://github.com/Kernald/tt-rss-bb10/blob/master/assets/main.qml#L9
By the way, note that you have predefined actions for Help and Settings. See the link before, I used them too.

Let's say you have the NavigationPane as the QML document loaded first upon application launch, so that's should be placed in MenuDefinition like that:
NavigationPane {
Menu.definition: MenuDefinition {
helpAction: HelpActionItem {
onTriggered: {
}
}
actions: [
ActionItem {
title: "Action 1"
imageSource: "asset:///images/ic_action1.png"
onTriggered: {
}
},
ActionItem {
title: "Action 2"
imageSource: "asset:///images/ic_action2.png"
onTriggered: {
}
}
]
}
firstPage: Page {
}
}
Note, that there might be up to 4 elements and HelpActionItem as well SettingsActionItem are already defined if you want to implement similar menu entries.

TableView is invisible

I'm trying to set something up, where there's a a HorizontalHeaderView that spans the entire width of the window, and a TableView that also spans the entire width of the window, along with stretching down to the bottom of the window. I also wanted a TextField and Button side by side, to sit on top of all this.
So far, I've gotten the TextField and Button to sit at the top, and part of the HorizontalHeaderView to be visible, but the TableView is completely invisible. I've tried fiddling around with height, Layout.preferredHeight, etc. but nothing makes it stretch to the bottom and fill the width of the window.
Here's what I've got so far:
import QtQuick 6.0
import QtQuick.Controls.Basic 6.0
import QtQuick.Layouts 6.0
ApplicationWindow {
title: "Portmod"
width: 640
height: 480
visible: true
header: TabBar {
id: mainTabBar
width: parent.width
TabButton {
text: "Manage"
width: implicitWidth
}
TabButton {
text: "Search"
width: implicitWidth
}
}
StackLayout {
id: mainStackLayout
currentIndex: mainTabBar.currentIndex
ColumnLayout {
id: manageTab
RowLayout {
TextField {
placeholderText: "Filter packages..."
}
Button {
text: "Filter"
}
}
HorizontalHeaderView {
id: installedPackagesHeader
syncView: installedPackagesTable
}
TableView {
id: installedPackagesTable
columnSpacing: 1
rowSpacing: 1
clip: true
model: installedPackagesModel
Keys.onUpPressed: installedPackagesTableVerticalScrollBar.decrease()
Keys.onDownPressed: installedPackagesTableVerticalScrollBar.increase()
Keys.onLeftPressed: installedPackagesTableHorizontalScrollBar.decrease()
Keys.onRightPressed: installedPackagesTableHorizontalScrollBar.increase()
ScrollBar.vertical: ScrollBar {
id: installedPackagesTableVerticalScrollBar
parent: installedPackagesTable
}
ScrollBar.horizontal: ScrollBar {
id: installedPackagesTableHorizontalScrollBar
parent: installedPackagesTable
}
delegate: Rectangle {
implicitWidth: 300
implicitHeight: 25
Text {
text: display
anchors.left: parent.left
}
}
}
}
Rectangle {
id: searchTab
width: parent.parent.width
height: parent.parent.height
}
}
}
Here's my custom QSortFilterProxyModel and QAbstractItemModel:
class InstalledPackagesProxyModel(QSortFilterProxyModel):
def __init__(self, data: list[list]) -> None:
super().__init__()
self.realModel = InstalledPackagesModel(data)
self.setSourceModel(self.realModel)
def get_atom(self, index: QModelIndex) -> Atom:
"""
Returns a reference to the source index instead of proxy index, to handle the sorted view.
"""
mapped_index = self.mapToSource(index)
data = [tuple(pkg_data_list) for pkg_data_list in self.realModel._data]
return Atom(f"{data[mapped_index.row()][2]}/{data[mapped_index.row()][0]}")
class InstalledPackagesModel(QAbstractTableModel):
def __init__(self, data: list[list]):
super(InstalledPackagesModel, self).__init__()
self._data = data
self.header_labels = ["Name", "Use Flags", "Category", "Version"]
def data(self, index, role):
if role == Qt.DisplayRole: # type: ignore
value = self._data[index.row()][index.column()]
if isinstance(value, Atom):
return str(value)
return value
def rowCount(self, index):
return len(self._data)
def columnCount(self, index):
try:
return len(self._data[0])
# If there are no installed mods in the prefix
except IndexError:
return 1
def headerData(self, section, orientation, role=Qt.DisplayRole): # type: ignore
if role == Qt.DisplayRole and orientation == Qt.Horizontal: # type: ignore
return self.header_labels[section]
return QAbstractTableModel.headerData(self, section, orientation, role)
This is what it looks like:
You need to use anchors.fill: parent on the StackView so it fills out its parent and has a proper size. Furthermore the HorizontalHeaderView needs to get a implicitHeight and the TableView should set Layout.fillWidth and Layout.fillHeight to true.
You need to use Layout.fillWidth and Layout.fillHeight to span to the full width and height of layouts.

}

I figured out that I needed to set the columnWidthProvider to this:
return Window.width / installedPackagesTableView.model.columnCount()
This is my full code for the TableView:

columnWidthProvider: function () {
return Window.width / installedPackagesTableView.model.columnCount()
}
rowHeightProvider: function (row) {
return 30;
}
onWidthChanged: installedPackagesTableView.forceLayout()
Layout.fillWidth: true
Layout.fillHeight: true
Keys.onUpPressed: function () {
if (selectedRow != 0) {
selectedRow -= 1;
}
// Move scrollbar up if the selectedRow is going to be invisible
if (selectedRow == topRow) {
installedPackagesTableVerticalScrollBar.decrease()
}
}
Keys.onDownPressed: function () {
if (selectedRow != installedPackagesModel.rowCount() - 1) {
selectedRow += 1;
// Move scrollbar down if the selectedRow is going to be invisible
if (selectedRow == bottomRow) {
installedPackagesTableVerticalScrollBar.increase()
}
}
}
Keys.onReturnPressed: installedPackagesModel.getAtom(selectedRow)
ScrollBar.vertical: ScrollBar {
id: installedPackagesTableVerticalScrollBar
}
ScrollBar.horizontal: ScrollBar {
id: installedPackagesTableHorizontalScrollBar
}
delegate: ItemDelegate {
highlighted: row == installedPackagesTableView.selectedRow
onClicked: installedPackagesTableView.selectedRow = row
onDoubleClicked: installedPackagesModel.getAtom(row)
text: model.display
}
}

How to force active focus/select QML Tab under QML TabView?

I have a TabView with 3 Tabs and I want to change the focus/select the third Tab when a button is pressed. I've tried forceActiveFocus, but it does not work.
//.qml
TabView {
Tab {
id: redTab
title: "Red"
Rectangle { color: "red" }
}
Tab {
id: blueTab
title: "Blue"
Rectangle { color: "blue" }
}
Tab {
id: greenTab
title: "Green"
Rectangle { color: "green" }
}
}
ToolButton {
inconSource: "lock.png"
onClicked: {
greenTab.forceActiveFocus() // does not work?
}
}
Set the currentIndex:
TabView {
id: tabView
//...
}
//...
tabView.currentIndex = 2

If you want to add a QML control into a cell you just have to define custom delegate. Since you need different delegates for different columns it can be done in a bit "tricky" way with Loader. See my example below:
Component {
id: comboDelegate
ComboBox {
model: ListModel {
ListElement { text: "Banana" }
ListElement { text: "Apple" }
ListElement { text: "Coconut" }
}
}
}
Component {
id: textDelegate
Text {
text: itemText
}
}
TableView {
Layout.fillWidth: true
Layout.fillHeight: true
TableViewColumn{ role: "col1" ; title: "Column1" }
TableViewColumn{ role: "col2" ; title: "Column2" }
TableViewColumn{ role: "col3" ; title: "Column3" }
model: ListModel {
id: myModel
}
itemDelegate: Item {
height: 25
Loader {
property string itemText: styleData.value
sourceComponent: styleData.column === 0 ? comboDelegate : textDelegate
}
}
}
Try this:
TableView {
TableViewColumn{ role: "col1" ; title: "Column1" }
TableViewColumn{ role: "col2" ; title: "Column2" }
TableViewColumn{ role: "col3" ; title: "Column3" }
model: ListModel {
id: myModel
}
}
Button {
text: "Add row"
onClicked: {
myModel.append({col1: "some value",
col2: "Another value",
col3 : "One more value" });
}
}

C++ object not found inside nested ListView in QML

I have a ListView nested inside another ListView in my qml. Both the ListViews are being populated by a data models which I get from a C++ class SelectRoomView. This is the code for my qml file:
import bb.cascades 1.0
import Data.SelectRoomView 1.0
import "commons"
Page {
id: pageSelectARoom
property alias currentPage: pageSelectARoom
property string propId
attachedObjects: [
SelectRoomView {
id: selRoom
}
]
onPropIdChanged: {
selRoom.propId = propId;
}
Container {
layout: StackLayout {
orientation: LayoutOrientation.TopToBottom
}
background: Color.create("#FFFFFF")
ScrollView{
horizontalAlignment: HorizontalAlignment.Fill
objectName: "scrollView"
ListView {
id: ruleList
dataModel: selRoom.modelRule
listItemComponents: [
ListItemComponent {
id: outerList
Container{
Label {
id: outerLabel
text: ListItemData.ruleName
textStyle.fontSize: FontSize.XXSmall
textStyle.color: Color.Black
}
Label{
id: outerId
text: ListItemData.ruleId
textStyle.fontSize: FontSize.XXSmall
textStyle.color: Color.Black
visible: true
}
ListView{
id: roomList
dataModel: selRoom.modelRoom //I get the message ReferenceError: Can't find the variable: selRoom
listItemComponents: [
ListItemComponent {
id: innerList
Label{
id: innerLabel
text: ListItemData.name
textStyle.fontSize: FontSize.XXSmall
textStyle.color: Color.Black
}
}
]
}
}
}
]
}
}
}
}
Upon running the app, ruleName of ruleList shows but not the innerLabel of roomList. The console displays the following message:
asset:///SelectARoom.qml:100: ReferenceError: Can't find variable: selRoom
asset:///SelectARoom.qml:100: ReferenceError: Can't find variable: selRoom
i.e., selRoom is not in scope for roomList (the nested list).
What am I doing wrong?
I cannot find a documentation of the ListView.listItemComponents property but it looks like some kind of delegate.
If the sub-list is part of the first list's delegate, it might not have access to global variables.
The QML docs state that delegates can access their position index and the variables of the model only.
Try to access other values outside the delegate's scope like to see whether that works
ListView {
id: roomList
Component.oncompleted: console.log(ruleList.height)
...
}
I found a solution, but it is not very efficient. The following is the new code:
Page {
id: pageSelectARoom
property alias currentPage: pageSelectARoom
property string propId
attachedObjects: [
SelectRoomView {
id: selRoom
}
]
onPropIdChanged: {
selRoom.propId = propId;
}
Container {
layout: StackLayout {
orientation: LayoutOrientation.TopToBottom
}
background: Color.create("#FFFFFF")
ScrollView{
horizontalAlignment: HorizontalAlignment.Fill
objectName: "scrollView"
ListView {
id: ruleList
dataModel: selRoom.modelRule
function getModelMain() { //the object 'selRoom' is accessible from this function.
return selRoom.modelRoom;
}
listItemComponents: [
ListItemComponent {
id: outerList
Container{
id: ruleContainer
function getModel() {
return ruleContainer.parent.getModelMain();
}
Label {
id: outerLabel
text: ListItemData.ruleName
textStyle.fontSize: FontSize.XXSmall
textStyle.color: Color.Black
}
Label{
id: outerId
text: ListItemData.ruleId
textStyle.fontSize: FontSize.XXSmall
textStyle.color: Color.Black
visible: true
}
ListView{
id: roomList
dataModel: ruleContainer.getModel()
listItemComponents: [
ListItemComponent {
id: innerList
Label{
id: innerLabel
text: ListItemData.name
textStyle.fontSize: FontSize.XXSmall
textStyle.color: Color.Black
}
}
]
}
}
}
]
}
}
}
}
Is there a better way to do this or is there an alternate more efficient solution? Waiting for response. Thanks.

Sorting listbox items as per the input provided by User in Qt/QML

I am trying to sort a list of items in the QML listview, as per the input provided by user. I have written the logic for sorting but unable to set the sorted model. It seems the sorted model is not assigned tp the actual model used for the original ListView. Please have a look to the code and let me know if I am doing something wrong.

//namesModel = filteredItems;
}
// The ListView:
ListView {

}
}
As shown above I guess the sorted model is not reassigned to the ListView. I am not sure. Please help me out. Thanks.
Taking a look at your code I guess you mean filtering items, and not sorting.
In your functions you try to assign a string value filteredItems to the listView.model property. You're probably getting an explicit error for that in your application log.
To solve this error you can use an auxiliary ListModel and populate it with just the items that fits your filter.
Try to replace all your code below the listDelegate Component with this:
ListModel{ id: filteredModel }
function getSortedItems(searchTerm) {
// Clear the aux model
filteredModel.clear();
// Add fitting items to the aux model
for (var i = 0; i < namesModel.count; i++) {
if (searchTerm === "" || namesModel.get(i).title.indexOf(searchTerm) === 0) {
filteredModel.append(namesModel.get(i));
}
}
}
// The ListView:
ListView {
id: listView
anchors.fill: parent; anchors.margins: 20
model: filteredModel
delegate: listDelegate
}
You can now do this with far less code using Array filter(). Below is an example written using Qt6.x syntax:
import QtQuick
import QtQuick.Controls
import QtQuick.Layouts
Page {
background: Rectangle { color: "#edecec" }
property var cities: [
{ title: "Mumbai" },
{ title: "Pune" },
{ title: "Bangalore" },
{ title: "Kolkata" },
{ title: "Hyderabad" },
{ title: "Nagpur" },
{ title: "Thane" }
]
ColumnLayout {
anchors.fill: parent
TextField {
id: textField
Layout.fillWidth: true
placeholderText: qsTr("Type something here")
}
ListView {
Layout.fillWidth: true
Layout.fillHeight: true
model: cities.filter( city => !textField.text || city.title.toLowerCase().indexOf(textField.text.toLowerCase()) !== -1 )
delegate: ItemDelegate { text: modelData.title }
}
}
}

Alternatively, you can consider using a ListModel combined with a DelegateGroup. The advantage of this is you do not need to repopulate a ListModel everytime the filter changes. Instead, you update the visibility of the item in the DelegateGroup:
import QtQuick
import QtQuick.Controls
import QtQuick.Layouts
import QtQml.Models
Page {
background: Rectangle { color: "#edecec" }
ListModel {
id: cities
ListElement { title: "Mumbai" }
ListElement { title: "Pune" }
ListElement { title: "Bangalore" }
ListElement { title: "Kolkata" }
ListElement { title: "Hyderabad" }
ListElement { title: "Nagpur" }
ListElement { title: "Thane" }
}
ColumnLayout {
anchors.fill: parent
TextField {
id: textField
Layout.fillWidth: true
placeholderText: qsTr("Type something here")
onTextChanged: delegateModel.refresh()
}
ListView {
Layout.fillWidth: true
Layout.fillHeight: true
model: DelegateModel {
id: delegateModel
model: cities
groups: [
DelegateModelGroup {
id: allItems
name: "all"
includeByDefault: true
},
DelegateModelGroup {
id: visibleItems
name: "visible"
}
]
filterOnGroup: "visible"
delegate: ItemDelegate { text: title }
function refresh() {
allItems.setGroups(0, allItems.count, ["all"]);
for (let i = 0; i < allItems.count; i++) {
let v = true;
let item = allItems.get(i);
if (textField.text) {
v = item.model.title.toLowerCase().indexOf(textField.text.toLowerCase()) !== -1;
}
if (v) allItems.setGroups(i, ["all", "visible"] );
}
}
}
}
}
Component.onCompleted: delegateModel.refresh()
}
