nadment opened a new issue, #5985:
URL: https://github.com/apache/hop/issues/5985
### What needs to happen?
When changing projects, the Explorer and Metadata perspectives are refreshed
as many times as there are tabs open in those views.
To speed up project switching, add a boolean to the HopGuiFileDelegate class
to indicate whether the GUI is in the process of closing all files.
```
public void closeAllFiles() {
this.isClosing = true;
for (IHopPerspective perspective :
hopGui.getPerspectiveManager().getPerspectives()) {
List<TabItemHandler> tabItemHandlers = perspective.getItems();
for (TabItemHandler tabItemHandler : handlers) {
IHopFileTypeHandler typeHandler = tabItemHandler.getTypeHandler();
typeHandler.close();
}
}
this.isClosing = false;
}
```
This way, when each tab is removed, unnecessary refreshing can be avoided.
```
public boolean remove(IHopFileTypeHandler fileTypeHandler) {
...
// Avoid refresh in a closing process (when switching project)
if (!hopGui.fileDelegate.isClosing()) {
// Refresh tree to remove bold
this.refresh();
// Update HopGui menu and toolbar
this.updateGui();
}
...
}
```
