Basic User Input Dialogs

Basic Dialogs (input, message, etc.)

PFXToolKitUI contains some basic dialog systems for accepting user inputs.

Some include:

• Single input
• Double input
• Showing messages (with yes/ok, no, cancel, none feedback)
• Keyboard and Mouse strokes
• File open/save pickers
• Colour picking

MemEngine360 also contains some custom variants such as:

• Memory region selector
• Module selector

These all use the user input info system. The base class is UserInputInfo.

For example, if you want to accept two integer inputs:

// Validate integer value -- display "Value too big" just for the fucks of it
Action<ValidationArgs> validateInteger = (a) => {
    if (!uint.TryParse(a.Input, NumberStyles.HexNumber, null, out _)) {
        if (ulong.TryParse(a.Input, NumberStyles.HexNumber, null, out _)) {
            a.Errors.Add("Value is too big. Maximum is 0xFFFFFFFF");
        }
        else {
            a.Errors.Add("Invalid UInt32.");
        }
    }
};

ScanningProcessor p = engine.ScanningProcessor;
DoubleUserInputInfo info = new DoubleUserInputInfo() {
    Caption = "Start and Length",
    Message = "Input the start and length values",
    ConfirmText = "Start", DefaultButton = true,
    LabelA = "Start address (hex)", 
    LabelB = "Length (hex)",
    TextA = "82600000",
    TextB = "4000"
    ValidateA = validateInteger, ValidateB = validateInteger,
    Footer = "Some custom footer text just above the buttons panel",
};

// Show dialog
if (await IUserInputDialogService.Instance.ShowInputDialogAsync(info) == true) {
    // This code below should never fail what so ever, since the validation
    // is ALWAYS run before ShowInputDialogAsync returns true
    uint start = uint.Parse(info.TextA, NumberStyles.HexNumber);
    uint length = uint.Parse(info.TextB, NumberStyles.HexNumber);
}

Creating custom user input info dialogs

This is some example code for registering/mapping your model type to a control:

UserInputDialogView.Registry.RegisterType<DoubleUserInputInfo>(() => new DoubleUserInputControl());

DoubleUserInputControl implements IUserInputContent. Either this or the single input version are fairly basic to help you get to grips on how it all works. For example, knowing what to do in UserInputInfo.UpdateAllErrors()
