I feel like it might have been addressed in the past already, but I can’t find a similar post.
On Juce 5.2.0,
I’m drawing a small (~15 rows / ~20 cols)
TableListBox which includes a third of custom cells in the form of inc/dec sliders. Hence these sliders make use of
TextButton to show the +/- sign buttons.
Since the table has quite a few columns, it is required to scroll the viewport to see all of them. But doing so impacts the performance a lot.
It seems the performance hit comes from drawing the text in the
TextButtons. I tried caching the custom components with
setBufferedToImage(true) but it does not seem to have any effect because of the Viewport.
Using a default
<Sans-Serif> font instead of my custom one seems to drastically reduce the performance hit. But is there any way to optimize the use of a custom font (created with
Typeface::createSystemTypefaceFor) when drawing text?
Here is the profiler’s stack:
