Work on the core of Event Commands

[Ghabry]

I implemented a system that allows to implement the simple event commands with the least amount of code via magic (tm).

The event Ui scans for GUI that ends on _argN where (N = parameter, use X for string). All it finds is auto-attached.

---

I also invented a OperandWidget that provides these three typical use cases:

• Value or Variable
• LCF Object or Variable
• Entire Party, Actor or Variable

_argN also attached here (uses subsequent values because it takes two args, so 2 will use 2 as operand and 3 as value)

Some GUI

Of course I recycle the RpgComboBox, so you profit from type-to-search and a "..." button to open a database window for direct editing.

Some code examples (boilerplate omitted):

Message Options. Unfortunately QtDesigner has no way to assign a button ID, otherwise this could be omitted :(

int i = 0;
for (auto& button : { ui->buttonTypeNormal, ui->buttonTypeTransparent }) {
	ui->groupWindowType_arg0->setId(button, i++);
}

i = 0;
for (auto& button : { ui->buttonPositionTop, ui->buttonPositionMiddle, ui->buttonPositionBottom }) {
	ui->groupWindowPos_arg1->setId(button, i++);
}

Change Item:

int i = 0;
for (auto& button : { ui->radioOpAdd, ui->radioOpRemove }) {
	ui->groupOp_arg0->setId(button, i++);
}

Here a screenshot to make it more obvious how it works:

Merging. The API is working good enough for me.

For more complex cases Event Widgets can also implement the function "apply()" now. This is useful for events that manipulate the event tree: They can rewrite the tree once on apply.
