D++ (DPP)
C++ Discord API Bot Library
Using Button Components

Discord's newest features support sending buttons alongside messages, which when clicked by the user trigger an interaction which is routed by D++ as an on_button_click event. To make use of this, use this code as in this example.

#include <dpp/dpp.h>
#include <dpp/unicode_emoji.h>
int main() {
dpp::cluster bot("token");
/* The event is fired when someone issues your commands */
bot.on_slashcommand([&bot](const dpp::slashcommand_t& event) {
/* Check which command they ran */
if (event.command.get_command_name() == "button") {
/* Create a message */
dpp::message msg(event.command.channel_id, "this text has a button");
/* Add an action row, and then a button within the action row. */
msg.add_component(
dpp::component().add_component(
dpp::component()
.set_label("Click me!")
.set_type(dpp::cot_button)
.set_emoji(dpp::unicode_emoji::smile)
.set_style(dpp::cos_danger)
.set_id("myid")
)
);
/* Reply to the user with our message. */
event.reply(msg);
}
});
/* When a user clicks your button, the on_button_click event will fire,
* containing the custom_id you defined in your button.
*/
bot.on_button_click([&bot](const dpp::button_click_t& event) {
/* Button clicks are still interactions, and must be replied to in some form to
* prevent the "this interaction has failed" message from Discord to the user.
*/
event.reply("You clicked: " + event.custom_id);
});
bot.on_ready([&bot](const dpp::ready_t& event) {
if (dpp::run_once<struct register_bot_commands>()) {
/* Create and register a command when the bot is ready */
bot.global_command_create(dpp::slashcommand("button", "Send a message with a button!", bot.me.id));
}
});
bot.start(dpp::st_wait);
return 0;
}
