Solved buttons to enable if conditions
-
Hi all,
I have two conditions inside a method. I also have two Radio Buttons,
buttonOne
andbuttonTwo
.My requirement is if I click
buttonOne
AND the other conditions are true ,eventOne
is true, else if I clickbuttonTwo
and other conditons are trueeventTwo
is truevoid MainWindow::mousePressEvent(QMouseEvent *event) { QPoint a = event->pos(); if (distance ( a,b) < 20 && ( a.x() > b.x() && a.x() < c.x() )) { eventOne = true; } else if (distance ( a,e) < 20 && ( a.x() > e.x() && a.x() < f.x() )) { eventTwo = true; }
How do I implement this?
Thank you

Hi
But MainWindow is not involved in clicking on the radio buttons as such.
Radio Buttons has their own signal for that and you connect that to a slot to handle that.
MousePress for MainWindow will not fire when you click on other widgets. Only when you click on MainWindow directly.But in mousePressEvent you can check their values of cause. so if u click first radio and then MainWidnow, you can check it there.

@mrjj Thank you.
What confusing me is how to check radiobutton value inside mousePressEvent. Could you show me an example? -

Hi
Its just
bool checked = ui->radioButtonName->isChecked();But you must click it first then on MainWin

Instead of using the MouseClick-event, you can add both of your RadioButtons to a
QButtonGroup
, connect theQButtonGroup::buttonToggled
signal to your function (check if your other condition is true) and check which RadioButton was "clicked" / toggled (has the "dot").QButtonGroup *btnGrp = new QButtonGroup(this); btnGrp->addButton(radioBtn_1, 0); btnGrp->addButton(radioBtn_2, 1); void (QButtonGroup::*signal)(int, bool) = &QButtonGroup::buttonToggled; // Send rButton ID and state (true / false) with signal connect(btnGrp, signal, this, &MainWindow::YOUR_SLOT);
Your slot could look like this:
void MainWindow::checkCondition(int id, bool checked) { if(checked && condition) // bool condition, if your other condition (calculation thing) is true { switch(id) { case 0: // RadioBtn 1 + Condition = true break; case 1: // RadioBtn 2 + Condition = true break; } } }
