Trouble with FileTreeComponent/setOpenessS

General JUCE discussion
3

i want to refresh the FileTree, to update the FileStructure (to see new files etc.)

Because of that i’m doing fileList->refresh(); but than all sub-items are closed.

So i have to restore the openness state

But because DirectoryContentsList loads the files dynamically in a background thread, the restoreOpeness will not work. Because if you open a subitem, it takes a while, to reload its content.

If found a workaround, restoring the update state 10 times in a second, so that the DirectoryContentsList has enough time to reload the subitems. Is there a more elegant solution?

[code]void FileTreeBrowser::buttonClicked( Button* button )
{
if (button==refreshButton)
{
opennesState=fileTree->getOpennessState(true);
fileList->refresh();

	DBG(opennesState->createDocument(String::empty));

	timerCountdown=10;
	startTimer(100);
}

}

void FileTreeBrowser::timerCallback()
{
if (opennesState!=0)
{
DBG(“Restore Openness State”)
fileTree->restoreOpennessState(*opennesState,true);
}

timerCountdown--;

if (timerCountdown<=0)
{
	stopTimer();
}

}[/code]
