Add Widgets to UScrollBox through C++

[anonymous_user_88daa2b7]

Hello, I’ve been looking around and only seen this implemented in Blueprint. I simply want to add some buttons to a ScrollBox in C++.

I tried simply adding a child button to see if that would work, but the game would just crash on load. My UScrollBox is the variable ‘directoryFolders’.

     void UDirectoryWidget::updateDirectoryFolders(){
         UButton testButton;
         directoryFolders->AddChild(&testButton);
     }

I also tried casting ‘testButton’ to (UWidget*) but that did not work either. Any insight would be great!

I found this:

Create UMG Button from C++

This worked well for me when I wanted to add it to an existing Panel

     void UMyGameInstance::MyPopulate(UPanelWidget *panel) {
         UTextBlock *tstText = ConstructObject<UTextBlock>(UTextBlock::StaticClass(), this);
         tstText->SetText(FText::FromString(TEXT("Test Button")));
         UButton *tstBtn = ConstructObject<UButton>(UButton::StaticClass(), this);
         tstBtn->AddChild (tstText);
         panel->AddChild(tstBtn);
     }

Thanks Ariegos! When I compiled it worked as expected, though it did say that ‘ConstructObject’ was depreciated. So I went ahead and used ‘NewObject’ instead and it seemed to work exactly the same without the warning.

This is what I did:

UButton* testButton = NewObject<UButton>(this, UButton::StaticClass());	
directoryFolders->AddChild(testButton);

Where the directoryFolders variable is a pointer to my ScrollBox.
