Yes, I have mouse tracking enabled.

Maybe my description of the issue was not very clear, sorry. When I click for the first time on the button, it does not change its style to QStyle.State_Sunken and then back to QStyle.State_Raised on release, this happens only on the every second click. Also button does not change its style on mouse hover.

Here is a minimal example

import sys from PyQt5.QtGui import * from PyQt5.QtCore import * from PyQt5.QtWidgets import * class MyDelegate(QStyledItemDelegate): def __init__(self): super(MyDelegate, self).__init__() self.buttonRect = None def sizeHint(self, option, index): fm = QFontMetrics(option.font) return QSize(150, fm.height() * 5 + fm.leading()) def paint(self, painter, option, index): name = index.data(Qt.DisplayRole) description = index.data(Qt.UserRole + 1) btnStyle = QStyle.State(index.data(Qt.UserRole + 2)) nameFont = QFont(option.font) nameFont.setWeight(QFont.Weight.Bold) fm = QFontMetrics(nameFont) padding = fm.lineSpacing() // 2 nameRect = QRect(option.rect) nameRect.setLeft(nameRect.left() + padding) nameRect.setTop(nameRect.top() + padding) nameRect.setRight(nameRect.right() - padding) nameRect.setHeight(fm.lineSpacing()) descrRect = QRect(option.rect) descrRect.setLeft(descrRect.left() + padding) descrRect.setTop(nameRect.bottom()) descrRect.setRight(descrRect.right() - padding) descrRect.setHeight(fm.lineSpacing()) btnText = "Add" textWidth = fm.width(btnText) self.btnRect = QRect(option.rect) self.btnRect.setLeft(descrRect.right() - textWidth * 2) self.btnRect.setTop(descrRect.bottom() + padding) self.btnRect.setRight(descrRect.right() - padding) self.btnRect.setHeight(fm.lineSpacing() * 2) borderRect = QRect(option.rect.marginsRemoved(QMargins(4, 4, 4, 4))) painter.save() pen = painter.pen() if option.state & QStyle.State_MouseOver: pp = QPen(option.palette.highlight().color()) pp.setWidth(2) painter.setPen(pp) painter.drawRect(borderRect) painter.setPen(pen) painter.setFont(nameFont) elided_text = fm.elidedText(name, Qt.ElideRight, nameRect.width()) painter.drawText(nameRect, Qt.AlignLeading, elided_text) painter.setFont(option.font) fm = QFontMetrics(QFont(option.font)) elided_text = fm.elidedText(description, Qt.ElideRight, descrRect.width()) painter.drawText(descrRect, Qt.AlignLeading, elided_text) button = QStyleOptionButton() button.text = btnText button.state = btnStyle button.rect = self.btnRect QApplication.style().drawControl(QStyle.CE_PushButton, button, painter) painter.restore() def editorEvent(self, event, model, option, index): if self.btnRect.contains(event.pos()): if event.type() == QEvent.MouseButtonPress: model.setData(index, QStyle.State_Sunken, Qt.UserRole + 2) elif event.type() == QEvent.MouseButtonRelease: model.setData(index, QStyle.State_Raised, Qt.UserRole + 2) self.do_something() else: model.setData(index, QStyle.State_Enabled | QStyle.State_HasFocus, Qt.UserRole + 2) else: model.setData(index, QStyle.State_Enabled, Qt.UserRole + 2) return super(MyDelegate, self).editorEvent(event, model, option, index) def do_something(self): print("button clicked") if __name__ == "__main__": app = QApplication(sys.argv) model = QStandardItemModel() for i in range(10): item = QStandardItem() item.setData(f"Item {i}", Qt.DisplayRole) item.setData("Item description, can be very long", Qt.UserRole + 1) item.setData(QStyle.State_Enabled, Qt.UserRole + 2) model.appendRow(item) listView = QListView() listView.setMouseTracking(True) listView.setItemDelegate(MyDelegate()) listView.setModel(model) listView.show() app.exec()

Hola,

Al no utilizar un thread para el calculo, tendrías que hacer algo así:

ui.myPushButton->setDisabled(true); QApplication::processEvents(); calcularFactorial(); ui.myPushButton->setEnabled(true);

El "processEvents" provoca un repintado de la aplicación de manera que se verán los botones deshabilitados. Si no lo haces, al ejecutarse secuencialmente, no vas a ver el cambio de estado de los botones.

@Dexter99 said in Pyqt5 help on button and grid layouts.:

The show is okay but now I want to add it in a grid layout.

Please show us what you've tried.

@SGaist Thanx mate :) Qt rox :D

@jsulm Oh. I haven't considered that. I'm definitely going to try that. I don't know why it didn't came to my mind. Thank you very much. I really appreciate your advice. I have been stuck at this problem for a week. I am glad there are people who are willing to help beginners.

need to check Qt classes for system settings and native look and feel,
and of adopting those changes for App.

Thanks,

In my understanding this is exact what onClicked does. From the online documentation:

"A click is defined as a press followed by a release, both inside the MouseArea (pressing, moving outside the MouseArea, and then moving back inside and releasing is also considered a click)."

MouseArea { anchors.fill: parent onClicked: console.log("released") onPressed: console.log("pressed") }

I create MyClass and pass 4 images to QML in main.cpp

class.h

#ifndef MYCLASS_H #define MYCLASS_H #include <QDebug> #include <QObject> class MyClass : public QObject { Q_OBJECT Q_PROPERTY(QString imagePath READ imagePath WRITE setImagePath NOTIFY pathChanged); public: explicit MyClass(QObject *parent = 0); MyClass(QString path) { m_imagePath = path; } QString imagePath(); void setImagePath(const QString & path); signals: void pathChanged(QString path); private: QString m_imagePath; }; #endif // MYCLASS_H

main.cpp

QApplication app(argc, argv); app.setWindowIcon(QIcon("qrc:/images/logo.ico")); QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:/main.qml"))); QList<QObject*> dataList; dataList.append(new MyClass("/images/images/zaglowek.png")); dataList.append(new MyClass("/images/images/pilot.png")); dataList.append(new MyClass("/images/images/uklad_jezdny.png")); dataList.append(new MyClass("/images/images/nozne_sterowanie.png")); engine.rootContext()->setContextProperty("myModel", QVariant::fromValue(dataList));

For Now MyClass has only image path, but it will also set state (checked-unchecked) and animation (enable-disable).
I would like to reload this QList ( with another images, states etc. ) when button ( one of three ) is clicked ( TButton.qml ).
How to do it ? Please help.

@JulienD
Np. You can style the whole application however. All controls etc
can be controlled with style sheet.
Just not Caption :)

これで行けました。

function Controller()
{

}

Controller.prototype.FinishedPageCallback = function()
{
buttons.CommitButton.hide();
}

Resolved.

When i played with second usb monitor i changed first hdmi monitor modes depth to 16. Now i set 24 bits in xorg.conf and all UI is OK.

Thanks for all.
