Unsolved Font Size Problem

[ZekDe]

Hi friends,
I'm running my codes and first groupBox's font size equals label above ,you will understand what I mean .These are my codes. groupBox_1 giving my intention result but groupBox giving labelBluetoothAdress fontsize.I cannot solve it.

/// \brief labelTitle
//
mfont.setPointSize(round(10*ui->labelTitle->geometry().height()/gbox));
ui->labelTitle->setFont(mfont);
ui->labelTitle->setStyleSheet(QStringLiteral("color: #0095d6"));
ui->labelTitle->setAlignment(Qt::AlignHCenter);

            /// \brief labelBluetoothAdress
            ///
            mfont.setPointSize(round(10*ui->labelBluetoothAdress->geometry().height()/10));
            ui->labelBluetoothAdress->setFont(mfont);
            ui->labelBluetoothAdress->setAlignment(Qt::AlignHCenter);
            /*********///6 adet Group Box nesnelerini uygun şekilde yerleştirmek için başlık ve bluetooth adresinin yazılacağı nesnelerin yükseklikleri dahil edilmiyor.
            //int hh = round(h - 1.6*(ui->labelTitle->geometry().height() + ui->labelBluetoothAdress->geometry().height()));
            /*********/
            //////////Tüm groupBox Ayarları////////////
            ///
            /// \brief groupBox
            ///
            QRect gb;

            gb = ui->groupBox->geometry();
            mfont.setPointSize(round(gb.height()/gbox));
            mfont.setBold(false);
            ui->groupBox->setFont(mfont);

            mfont.setPointSize(round(ui->customPlot->geometry().height()/cPlot));
            mfont.setBold(false);
            ui->customPlot->xAxis->setTickLabelFont(mfont);
            ui->customPlot->yAxis->setTickLabelFont(mfont);

            mfont.setPointSize(round(ui->labelDisplay->geometry().height())/cnst);
            mfont.setBold(true);
            ui->labelDisplay->setFont(mfont);
            ui->labelDisplay->setAlignment(Qt::AlignRight);

            mfont.setPointSize(round(ui->labelUnity->geometry().height()/cnst));
            mfont.setBold(true);
            ui->labelUnity->setFont(mfont);
            ui->labelUnity->setAlignment(Qt::AlignLeft);


            /// \brief groupBox_1
            ///
            gb = ui->groupBox_1->geometry();

            mfont.setPointSize(round(gb.height()/gbox));
            mfont.setBold(false);
            ui->groupBox_1->setFont(mfont);

            mfont.setPointSize(round(ui->customPlot_1->geometry().height()/cPlot));
            mfont.setBold(false);
            ui->customPlot_1->xAxis->setTickLabelFont(mfont);
            ui->customPlot_1->yAxis->setTickLabelFont(mfont);

            mfont.setPointSize(round(ui->labelDisplay_2->geometry().height())/cnst);
            mfont.setBold(true);
            ui->labelDisplay_2->setFont(mfont);
            ui->labelDisplay_2->setAlignment(Qt::AlignRight);

            mfont.setPointSize(round(ui->labelUnity_2->geometry().height()/cnst));
            mfont.setBold(true);
            ui->labelUnity_2->setFont(mfont);
            ui->labelUnity_2->setAlignment(Qt::AlignLeft);

@ZekDe said in Font Size Problem:

mfont.setPointSize(round(10*ui->labelBluetoothAdress->geometry().height()/10));

You multiply by 10 and then devide by 10 - what's the point?

I got this problem,I am getting 'size < 0' this is why I think program assign default value maybe previous value .

Hi,

In addition to the point made by @jsulm, when are you calling that code ? If it's in the constructor then you are using invalid values. No geometry is known at construction time, it's only when a widget is shown that its geometry becomes real.
