As it was stated in U++ docs, I may post additional argument to a function creating a toolbar:
void OnUpdateGraphToolbar(GraphProjectUI &ui, bool newTabSelected)
{
ui.toolsGraphs.Clear();
ui.toolsGraphs.Set(callback1(this, &GraphProject::SetToolsGraphs, &ui));
}
void SetToolsGraphs(Bar &b, GraphProjectUI *ui)
{
gecs.InstallToDropCtrl(ui->colls);
b.Add(ui->colls, 100, ui->colls.GetStdSize().cy);
b.Add(!ui->colls.GetData().IsNull(), GraphEditorImg::graph_add, callback(this, &GraphProject::Dummy));
b.ToolGapRight();
b.Separator();
b.Add(false, GraphEditorImg::graph_remove, callback(this, &GraphProject::Dummy));
}
But when I try to post two additional arguments: void OnUpdateGraphToolbar(GraphProjectUI &ui, bool newTabSelected)
{
ui.toolsGraphs.Clear();
ui.toolsGraphs.Set(callback2(this, &GraphProject::SetToolsGraphs, &ui, newTabSelected));
}
void SetToolsGraphs(Bar &b, GraphProjectUI *ui, bool newTabSelected)
{
if (newTabSelected)
gecs.InstallToDropCtrl(ui->colls);
b.Add(ui->colls, 100, ui->colls.GetStdSize().cy);
b.Add(!ui->colls.GetData().IsNull(), GraphEditorImg::graph_add, callback(this, &GraphProject::Dummy));
b.ToolGapRight();
b.Separator();
b.Add(false, GraphEditorImg::graph_remove, callback(this, &GraphProject::Dummy));
}
-- it fails to compile!
I may of course work around this, but IMO it is a U++ bug.
