}
Component Documentation
MessageOK
Simple message dialog with an OK button.
var messageOK = new ImGuiPopups.MessageOK();
messageOK.Open("Title", "Your message here");
Input Components
Get validated input from users:
// String input
var inputString = new ImGuiPopups.InputString();
inputString.Open("Enter Text", "Label:", "default", result => HandleString(result));
// Integer input
var inputInt = new ImGuiPopups.InputInt();
inputInt.Open("Enter Number", "Value:", 42, result => HandleInt(result));
// Float input
var inputFloat = new ImGuiPopups.InputFloat();
inputFloat.Open("Enter Float", "Value:", 3.14f, result => HandleFloat(result));
SearchableList
Searchable selection from a list of items:
var searchableList = new ImGuiPopups.SearchableList<MyClass>();
searchableList.Open(
title: "Select Item",
label: "Choose an item:",
items: myItemList,
defaultItem: null,
getText: item => item.DisplayName, // How to display items
onConfirm: selected => HandleSelection(selected),
customSize: new Vector2(400, 300)
);
FilesystemBrowser
Advanced file and directory browser:
var browser = new ImGuiPopups.FilesystemBrowser();
// Open file
browser.Open(
title: "Open File",
mode: FilesystemBrowserMode.Open,
target: FilesystemBrowserTarget.File,
startPath: Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
onConfirm: path => OpenFile(path),
patterns: new[] { "*.txt", "*.md" } // Optional file filters
);
// Save file
browser.Open(
title: "Save File",
mode: FilesystemBrowserMode.Save,
target: FilesystemBrowserTarget.File,
startPath: currentDirectory,
onConfirm: path => SaveFile(path)
);
Custom Modal
Create custom modal dialogs:
var customModal = new ImGuiPopups.Modal();
customModal.Open("Custom Dialog", () => {
ImGui.Text("Custom content here");
if (ImGui.Button("Close"))
{
ImGui.CloseCurrentPopup();
}
}, new Vector2(300, 200));
Advanced Usage
Custom Sizing
All popups support custom sizing:
// Fixed size
popup.Open("Title", "Content", new Vector2(400, 300));
// Auto-size (Vector2.Zero)
popup.Open("Title", "Content", Vector2.Zero);
Text Layout Options
Prompts support different text layout modes:
var prompt = new ImGuiPopups.Prompt();
prompt.Open("Title", "Long message text here...",
buttons: new() { { "OK", null }, { "Cancel", null } },
textLayoutType: PromptTextLayoutType.Wrapped, // or Unformatted
size: new Vector2(400, 200)
);
Validation and Error Handling
Input components provide built-in validation:
inputInt.Open("Enter Age", "Age (1-120):", 25, result => {
if (result < 1 || result > 120)
{
messageOK.Open("Error", "Age must be between 1 and 120");
return;
}
ProcessAge(result);
});
