Escape Room Limited Time Room 5 Bug

June 9, 2012 by blogmeister·8 Comments

This game is cool. However, I was stuck in Room 5 (Riddle) and was forced to look for answers because the game has a bug.

The question is: You have 10 lit candles. All of a sudden a gust of wind put out 7 of them. How many lit candles are left?

Now … the answer in the game is 7. Which is wrong. It should be 3, right?

I have no idea why they made 7 the correct answer. This bug really got me stuck. Even the walkthrough editor said so himself that the game’s question may had been worded incorrectly.

Auto Adjust JTable Row Height

June 7, 2012 by blogmeister·0 Comments

Now this, is the best code snippet I found in Java that can auto adjust the JTable row height regardless what kind of renderer component is used.

I had been using some short code snippet that sets a JTextPane or JEditorPane content, then getting the height. However, when my content was full of HTML tags, the height returned really messed my JTable.

This code I found in Stack Overflow by user camickr really is the best solution for auto adjusting all rows heights of a JTable based on content.

try {
    for (int row=0; row<table.getRowCount(); row++) {
        int rowHeight = table.getRowHeight();
        for (int column=0; column<table.getColumnCount(); column++) {
            Component comp = table.prepareRenderer(table.getCellRenderer(row, column), row, column);
            rowHeight = Math.max(rowHeight, comp.getPreferredSize().height);
        }
        table.setRowHeight(row, rowHeight);
    }
} catch(ClassCastException e) { }

try {

for (int row=0; row<table.getRowCount(); row++) {

int rowHeight = table.getRowHeight();

for (int column=0; column<table.getColumnCount(); column++) {

Component comp = table.prepareRenderer(table.getCellRenderer(row, column), row, column);

rowHeight = Math.max(rowHeight, comp.getPreferredSize().height);

}

table.setRowHeight(row, rowHeight);

}

} catch(ClassCastException e) { }

How To Detect If Device is Android Tablet Or Smartphone

June 6, 2012 by blogmeister·0 Comments

The best and easiest way to have your app determine if the device is a smartphone or a tablet is to place a boolean value in a specific value file such as res/values-xlarge.

<resources>
    <bool name="isTablet">true</bool>
</resources>

</resources>

Then, in the folder res/values, you can add the same XML code but with a false value.

<resources>
    <bool name="isTablet">false</bool>
</resources>

<bool name="isTablet">false</bool>

</resources>

In your Android code, you can get the value with this code:

boolean isTablet = getResources().getBoolean(R.bool.isTablet);
if (isTablet) 
    System.out.println("this is a tablet!");
else
    System.out.println("this is not a tablet!");

boolean isTablet = getResources().getBoolean(R.bool.isTablet);

if (isTablet)

System.out.println("this is a tablet!");

else

System.out.println("this is not a tablet!");
