<p class="MsoNormal"><span lang="EN-US">Hello Community,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">In one of pyqgis app built in QGIS 2.18 I have a waiting message to let know the user to wait until a project opens.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I simplified the process in the following scrip:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">from qgis.PyQt import QtWidgets<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">message = "Wait to open the airspace project..."<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">msg = QtWidgets.QMessageBox()<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">msg.setText(message)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">msg.show()<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">qgis.utils.iface.messageBar().pushMessage("Wait", message)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">for i in range(1000):<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> print(i)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">qgis.utils.iface.messageBar().pushMessage("Done", "The process is done")<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">msg.setText("The process is done")<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When I run the script as is in QGIS 2.18 the message "Wait to open the airspace project..." is displayed on both message bar and QMessageBox.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Then the loop starts and it display the i.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">And at the end the message "The process is done" is displayed in both message bar and QMessageBox.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">If I run the same scrip in 3.22.8-Bia³owie¿a, the loop starts and no wait message is displayed.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The QMessageBox is somehow displayed without any message.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">After the loop is done "The process is done" is displayed in both pushed bar and QMessageBox.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">What is strange "The process is done" disappear from the pushed bar and "Wait to open the airspace project..." is displayed.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So this behavior is useless for the user.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is anyway hot to make QGIS 3.22 to display these messages in the proper sequence as they used to be displayed in QGIS 2.18.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I hope you can access the video at this link. I explained the behavior and you can see it<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
