Gradient for chunks in QProgressBar

由 落花浮王杯 提交于 2019-12-12 16:25:34
问题 Is it possible to set a common gradient for all QProgressBar chunks? If use something like this: QProgressBar::chunk:horizontal { background: qlineargradient(x1: 0, y1: 0.5, x2: 1, y2: 0.5, stop: 0 green, stop: 1 white); margin-right: 2px; width: 10px; } the result will be http://labs.trolltech.com/blogs/wp-content/uploads/2007/06/progressbar_righttext.png but I want to obtain a one gradient, stretched to all chunks. Like this: http://labs.trolltech.com/blogs/wp-content/uploads/2007/06

PyQt Progressbar QThread not working when rendering a graph

由 空扰寡人 提交于 2019-12-11 14:22:55
问题 I looked at this answer here which was very helpful, but it's not working as expected when trying to render a plot. The plot is working but the progress bar is not progressing , it will just jump to 100% after the plot is rendered. Of course, I would like the progress bar to be progressing while the plot is rendering, not after it's finished. I think, I might be missing a PyQt function to somehow connect the event or the pyqt signal, but actually I have no idea how to fix this. Here is, what

问题 I try to make the progress bar update real-time with pyqt5, however, the documentation online seems very limited for now. I read online that I can use thread and signal to do that. However, the syntax seems changed in pyqt5. Can any experts here help? Main ui window. # -*- coding: utf-8 -*- # # Created by: PyQt5 UI code generator 5.9 # # WARNING!

问题 I am running ubuntu 11.04. This is what my progress bars look like: I am showing the progress bars in a batch processing window (one per batch item) and would like to use them as a status indicator (green while all is going well, red in case of errors, ...). I have tried several suggestions, including the ones made to this almost identical question. Unfortunately, I couldn't make it work and the documentation on customizing QProgressBars doesn't help me either, so I would be very grateful for

Is there circular QProgressbar with range (0,0) in qt?

由 吃可爱长大的小学妹 提交于 2019-12-04 06:41:43
问题 I want to have circular QProgressbar which it's appearance must look like the normal QProgressbar with the Range between 0 and 0. The code for the linear QProgressbar is some thing like below: QProgressBar *_progressBar = new QProgressBar(); _progressBar->setTextVisible(false); _progressBar->setRange(0, 0); but I want it to be circular. Is there any way to implement it in qt? 回答1: One day I wrote a simple class to implement a circular progress bar for my purposes (Qt 4.6). You can modify its

The way i thought i would do this it to do something like this in the other class: gui.progressbar.setValue(some%) but i cant seem to make that work. the code for the gui class is something like: from PyQt4 import QtCore, QtGui from Run import RunProgram class Ui_mainLayout(QtGui.QWidget): def setupUi(self, mainLayout): mainLayout.setObjectName(_fromUtf8("mainLayout")) def setLayout(): self.basic_tab =

How to control QProgressBar with Signal

问题 Pushing the button starts 100 rounds cycle. With QLabel.setText() we update self.label from inside of scope of clicked() function. Aside from updating self.label we would like to update the progressbar as well. But since progressbar is a local variable we can't update it from inside of onClick() function. import time class ProgressBar(QtGui.QProgressBar): def __init__(self, parent=None, total=20): super(ProgressBar, self).__init__(parent=parent) self.setMinimum(1) self.setMaximum(105) self
