Method and apparatus for performing visual programming

An apparatus for performing visual programming, comprising:

• processing circuitry configured to
• determine a target role in a visual layout region of a target interface;
• cause a display to display an event building block set in an event building block triggering region of the target interface;
• add, in response to detecting a selection of a first event building block in the event building block set, the first event building block corresponding to the target role to a visual programming region of the target interface, the first event building block including a first begin block and a first end block, the first begin block and the first end block being arranged in the visual programming region based on a folding state of the first event building block;
• display a building block unfolding identifier associated with the first event building block in the visual programming region in a case that the first event block in the visual programming region is in a folded state;
• unfold the first event building block in response to detecting an unfolding instruction for the building block unfolding identifier, and displaying, in the visual programming region, the first event building block in an unfolded state;
• display an indicator in the visual programming region in association with the first event building block, the indicator indicating a position in the visual programming region to which a first function building block of the first event building block is to be added;
• receive a selection of the first function building block in at least one function building block corresponding to the first event building block displayed in a function building block triggering region of the target interface;
• determine, in response to detecting the selection of the first function building block in the at least one function building block corresponding to the first event building block displayed in the function building block triggering region, the first function building block;
• add, in response to detecting the selection of the first function building block, the first function building block corresponding to the target role to the visual programming region based on the position of the indicator;
• display a building block folding identifier associated with the first event building block in the visual programming region in a case that the first event building block in the visual programming region is in the unfolded state;
• and
• hide the first function building block in a first event region in response to detecting a folding instruction for the building block folding identifier, wherein
• the first begin block and the first end block are arranged transversely in the visual programming region in the case that the first event building block is in the folded state,
• the first begin block and the first end block are arranged longitudinally in the visual programming region in the case that the first event building block is in the unfolded state, and
• the first function building block is added to the visual programming region in response to detecting a drag operation on the first function building block.
