Progress
The progress control displays the progress of an operation.
Quick Start
#include <wui/control/progress.hpp>
// Horizontal progress
auto progress = std::make_shared<wui::progress>(
0, // from
100, // to
0 // current value
);
window->add_control(progress, {10, 10, 200, 20});
// Vertical progress
auto v_progress = std::make_shared<wui::progress>(
0, 100, 0,
wui::orientation::vertical
);
window->add_control(v_progress, {10, 50, 20, 200});
Orientation

enum class orientation
{
horizontal, // Horizontal
vertical // Vertical
};
API
Constructor
progress(int32_t from, int32_t to, int32_t value,
orientation orientation_ = orientation::horizontal,
std::string_view theme_control_name = tc,
std::shared_ptr<i_theme> theme_ = nullptr);
Parameters:
- from — range start
- to — range end
- value — current value
- orientation_ — orientation
- theme_control_name — theme name
- theme_ — theme
Methods
// Range
void set_range(int32_t from, int32_t to);
// Value
void set_value(int32_t value);
// Click callback
void set_click_callback(std::function<void(int32_t, bool)> click_callback);
// Progress points
void set_point(int32_t value, bool is_max);
Examples
File Download
auto download_progress = std::make_shared<wui::progress>(0, 100, 0);
window->add_control(download_progress, {10, 10, 300, 20});
// During download
void on_download_progress(size_t current, size_t total) {
int percent = (current * 100) / total;
download_progress->set_value(percent);
}
Vertical Volume Indicator
auto volume_progress = std::make_shared<wui::progress>(
0, 100, 50,
wui::orientation::vertical
);
volume_progress->set_click_callback([](int32_t value, bool is_max) {
set_volume(value);
});
window->add_control(volume_progress, {10, 10, 30, 200});
Progress with Markers
auto progress = std::make_shared<wui::progress>(0, 100, 0);
// Set markers
progress->set_point(25, false); // Minimum point
progress->set_point(75, true); // Maximum point
window->add_control(progress, {10, 10, 300, 20});
Indeterminate Progress
// For operations with unknown duration
auto indeterminate = std::make_shared<wui::progress>(0, 100, 0);
window->add_control(indeterminate, {10, 10, 200, 20});
// Animation
int value = 0;
auto timer = std::make_shared<wui::timer>(window, 100, [&]() {
value = (value + 5) % 100;
indeterminate->set_value(value);
});
