改变缩略图的大小。但发现并不会起作用。
|
||
|
|
|
||
|
|
## 原理：
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
void SObjectPropertyEntryBox::Construct( const FArguments& InArgs )
|
||
|
|
{
|
||
|
|
// check if the property metadata wants us to display a thumbnail
|
||
|
|
const FString& DisplayThumbnailString = PropertyHandle->GetProperty()->GetMetaData(TEXT("DisplayThumbnail"));
|
||
|
|
if(DisplayThumbnailString.Len() > 0)
|
||
|
|
{
|
||
|
|
bDisplayThumbnail = DisplayThumbnailString == TEXT("true");
|
||
|
|
}
|
||
|
|
|
||
|
|
// check if the property metadata has an override to the thumbnail size
|
||
|
|
const FString& ThumbnailSizeString = PropertyHandle->GetProperty()->GetMetaData(TEXT("ThumbnailSize"));
|
||
|
|
if ( ThumbnailSizeString.Len() > 0 )
|
||
|
|
{
|
||
|
|
FVector2D ParsedVector;
|
||
|
|
if ( ParsedVector.InitFromString(ThumbnailSizeString) )
|
||
|
|
{
|
||
|
|
ThumbnailSize.X = (int32)ParsedVector.X;
|
||
|
|
ThumbnailSize.Y = (int32)ParsedVector.Y;
|
||
|
|
}
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
