Redraw a TGListTree

ROOT
1

Hello,

I have a problem with the refresh of a TGListTree. In my program, I am creating a TGListTree of some items (itemPKI and a listPKI which a vector of items) with default icons. At one time, I have these following lines to change the icons:

[code]itemPKI->SetPictures(gClient->GetPicture(“img/red.png”),gClient->GetPicture(“img/red.png”)); //PKI

for(unsigned int i(0); i<listPKI.size();++i)
{
listPKI[i]->SetPictures(gClient->GetPicture(“img/red.png”),gClient->GetPicture(“img/red.png”));
}

gClient->NeedRedraw(fListDevices);[/code]

I found the last line on the forum, however I have still the same icons, I need to click on one of them to change all the icons. Is there a solution to refresh the list instantaneously?

Thank you,

Pierre-Louis

Hi Pierre-Louis,

Use fListDevices->ClearViewPort(); to clear the viewport and refresh the listtree.
