Estimates do not support, unless special means the PNG loaded into memory (converted into BMP may)

CodePudding user response:

Find a good one controls, that kind of like Windows 7 types of button controls can estimate, which exclude used,

CodePudding user response:

Should be directly support the new XE, old with PngImage, this looks good,

CodePudding user response:

PngImage only supports the TImage load Png image
TSpeedButton TBitBtn want to add the Png images can't add,
